v1.18: 01/15/2007
- added the option -biosdir to define bios directory path
- added the option -romdir to define rom directory path
- added the option -help to help display
- directory search fix : When you don't have the "roms/" and/or "bios/"
directory, the program will dump core (by Walter de Jong).
- O2Launcher works now, o2em ignore roms and bios path if o2Launcher
is running.
- quad display fix: changed the way quad chars are drawn, fixes problems
in KTAA as well as score display in Black Hole and Red Baron (Soeren Gust)
- support for Soerens MegaCART bank switching (Information about
how to use this will be included in the next verison of Soerens
Bios-Documentation) (Soeren Gust)
- new feature in debugger: savevpp to make an uncompressed dump of the VPP
screen and slide data (Soeren Gust)
- dis48: fix to work under linux again (Soeren Gust)
- init_sound volume is not set to maximum (By Gunter Wambaugh)
- added makefile and options for freeBSD (By Gunter Wambaugh)
- Other minor fixes.
all the next changes were implemented by Manopac:
- added the option -s0 to redefine the system keys (see o2em.txt for usage)
- bugfix: highscore-file is only written if scoretype is set
- changed Default Stick 1 key from right <Control> to "L" to enable Fire and
movement at the same time
- two joysticks can be used now: first stick in command-line is mapped to joystick 1,
second to joystick 2 (compatible to old command line options)
- changes in debugger: status of registers is now displayed after instructions
are executed
- new features in debugger: savedatah and savedatab to save data from memory
as sourcecode ("db xxx")
- changed Default Stick 1 key from right <Control> to "L" to enable Fire
and movement at the same time
- two joysticks can be used now: first stick in command-line is mapped to
joystick 1, second to joystick 2 (compatible to old command line options)
- changes in debugger: status of registers is now displayed after
instructions are executed
- new features in debugger: savedatah and savedatab to save data from memory
as sourcecode ("db xxx")
- removed the limit that KTAA was the only 3K enabled rom (every
rom divideable by 3K is allowed now)
- dis48: added option -bios to disassemble bios (start at address 0)
- dis48: empty line after each page
- new feature to save the highscore in games (F6 to set in game)
- new feature to save/load state (F2/F3) (with command line option savefile)
- new features in debugger: savevdc and saveext to save data from Extram and VDC
- new feature in debugger: viewsprite
- new feature in debugger: bp (breakpoint) - o2em runs with output until
breakpoint is reached (bpc to clear)
- new feature in debugger: so (step over) - runs to next instruction in memory
- more explicit register display (P1 & PSW)
- fixed the "double size sprites are shifted only 1 instead of 2 pixles" bug
- new features in debugger (load / save file, change values in memory,
assemble to memory)
v1.17: 05/01/2005
- BIOS identified by CRC, to activate a specific BIOS type: -o2rom, or
-g7400, or -c52, or -jopac. The old form can be used. See O2EM.txt for more.
- Automatic identification of BIOS VP+ when the selected game is only VP+.
- Creation of the standard directories (ROMS, BIOS, VOICE) when uncompressing
O2EM archive.
- ATLANTIS, FROGGER, COMANDO NOTURNO and CATCH THE BALL now work without
graphic bugs. This correction is based on a specific patch for each game.
Thanks Rafael Cardoso for reports these bugs.
V1.16: 12/28/2004
- Fixed a slowdown in Pick Axe Pete (based on a patch by Arlindo de
Oliveira).
- Reverted back to the old palette for O2 games, while using the new
palette for Videpac Plus games (selected based on bios version in use).
V1.15: 12/12/2004
- Added support for 12kb and 16kb games. Trans American Rally+ works now.
- Added fixes to the VP+ gfx emulation made by Soeren Gust. Flashpoint
works properly now.
- Fixed a bug in the Windows-specific emulation timing code that caused
the emulator to crash when run on a Windows machine which was on for a
few days without a reboot.
- Fixed a bug in the emulation of the DAA instruction, which caused bugs
in the score of several games (Le Tresor Englouti, Cosmic Conflict, etc.).
- Fixed instruction timings (patch by Soeren)
- Modified the palette to use values calculated from the Videopac+ RGB
encoder specs by René van den Enden, instead of guessed values.
- Other minor fixes.
V1.01: 10/23/2002
- Major speed optimization.
- Implemented VDC <-> VP+ collision detection.
- On the original machines it is possible to make all VDC
colors bright by clearing P17. This affects the background and
dark grid colors. Implemented. Now the Killer Bees! intro screen
works correctly.
- Fixed the wrong color order when mixing between VP+ and VDC graphics.
Jopac Moto Crash now works. Fixed by Soeren Gust.
- Now the VBLANK pulse is visible on the T1 input. This can be used
to differentiate between PAL and NTSC.
- Other minor fixes.
V1.00: 09/12/2002
- Implemented complete Videopac+ G7400 emulation. Implemented it from
scratch, based on the EF9340/41 datasheet (sent by Simon Scudder), on
the technical docs made by Soeren Gust and disassembling the VP+ bios.
You will need a Videopac+ bios image file in order to use this feature.
You can use the -bios option to select it, rename the file to o2rom.bin,
or select it in O2EM Launcher settings. Please note that a few O2 games
do not work with the VP+ bios, so most likely you will need both bios
versions to be able to run all the games. For copyright reasons these
files are not included with O2EM, but you can find them in the Internet.
- Added a default configuration file. Now you can specify your preferred
options in a configuration file, instead of typing it every time you
execute the emulator. The command line options override the default
settings in the file. See O2EM.txt for more.
- Extended the -s1 and -s2 switches to allow customizable keys with the
joystick emulation. Based on a patch written by Zimmerman that
implemented customizable keys it in a different way. See O2EM.txt for
more.
- Added support to the Four in 1 Row game.
- Added the -exrom switch to enable the use of a special ROM mapping mode.
See O2EM.txt for more.
- Improved the sound with Frogger and Popeye.
- Minor fixes.
V0.90: 08/07/2002
- Fixed the color palette, based on screen shots from a real O2 console.
- Fixed a bug in the sprite drawing priority. Now in several games the
sprites look better (Demon Attack, Turtles, Atlantis, Computer Golf,
Football, Helicopter Rescue, etc.).
- Modified the emulation of sprites and characters in the border region of
the screen. Fixed the bug of character wrapping to the other side of the
screen and other problems (Atlantis and others). Now the main characters of
P.T.Barnum's Acrobats! do not fall from the edge of screen.
- Fixed the audio pitch and implemented white noise emulation. Now
explosions sound much better!
- Fixed a background line blinking problem that used to affect lots of
games.
- Fixed the color bar at the left of the screen.
- Enhanced the support for European/Pal games. Now several games look and
play better. Shark Hunter intro works correctly. Frogger and Depth Charge
are fully playable !
- Implemented an audio filter that accurately emulates the behavior of the
low-pass filter present in the audio output of the real console. The sound
is better now. (Enable it with -filter).
- Fixed the screen size. Now you can see all the graphics in the game,
including the time in Labyrinth.
- Implemented Dot Grid emulation. Now Marksman is playable.
- Implemented a cached video emulation, to make it run faster with slow
machines / video cards.
- Implemented screen shots (use the F8 key and the -scshot option)
- Implemented the sprite shifted/smooth modes. Now the main character of
Q*bert looks hi-res.
- Several minor fixes.
The following fixes were made by Soeren Gust:
- Implemented the missing JNI instruction.
- Implemented the 1kb data ROM / 3kb program ROM addressing mode used by
Musician.
- Fixed the height of the grid lines.
- Added support for 3Kb per bank
V0.87: 06/21/2002
- Fixed a collision bug introduced with version 0.86.
Now Cosmic Conflict runs again. Thanks to Dan Boris for reporting
this bug.
- Implemented the option to set the O2 bios file name/dir, as
requested by my friend Heitor, to enable him to support it with his
nice O2EMLauncher frontend for O2EM 0.8x, as requested by its users.
Get O2EMLauncher here: http://www.odyssey.com.br/o2emlauncher/
Version 0.86:
- Fixed a bug in the drawing of quad characters. Now you can play
Q*Bert and Nimble Numbers Ned. Some other games will also have
improved graphics or text (Popeye, Super Cobra, etc.) .
- Fixed another bug in the collision detection. Now Demon Attack
works correctly.
Version 0.85:
- Fixed the collision detection. Now you can play Killer Bees!
- Implemented partial support to mid-screen changes to the VDC
registers without interrupts. Now several games look better, and some
that didn't work can be played, including Power Lords and Super Cobra.
- Fixed a bug in the video emulation that made some games like Turtles
and Shark Hunter appear with some strange static characters.
Version 0.80:
The following changes were already implemented by Daniel Boris in version
0.701. Implemented them again in the sources based on version v0.65:
- Fixed a bug in the CPU core related to the handling of branch
instructions near page boundaries. (Without it Sid the Spellbinder
crashed after the first level).
- CPU core now jumps to the correct address on an external interrupt.
Killer Bees runs again.
- Fixed shape of '$' character and added missing 64th character to
character set (ripped the correct character data from the v0.701
executable file).
- Fixed bug in drawing of bottom grid line.
- Added Voice support. Re implemented it from scratch, based on O2
technical specs released by Dan Boris and disassembling Smithereens
and Turtles (now it always work with Turtles).
The following changes are new to version 0.80:
- Updated the code to compile with Allegro 4.0.x and to work
without changes under Windows, Linux and DOS, with optimizations
for each.
- Implemented the option of windowed or fullscreen video modes,
with scaling, centering and optional 50% scanlines.
- Cleaned the code to make it more portable and maintainable.
- Improved timing, using the most accurate way available for
each platform.
- Fixed the keyboard scan code translation table.
- Fixed and improved the built-in debugger.
- Fixed the reset. It now works with Turtles.
- Fixed joystick detection code.
- Implemented variable speed control relative to original O2.
- Implemented individual volume control for sounds and voice.
- Implemented Pause/Information (F1).
- Avoided collision of keyboard input with key joystick
emulation. Now Caps Lock enables/disables the W,D,S,A,Space keys
for keyboard input when they are used by joystick emulation.
Works well with games like K.C.'s Krazy Chase.
- It now releases more CPU time to the system (if possible).
- Other minor changes/fixes.

O2EM v1.18 (Jan/2007)
an Odyssey 2 & Videopac+ emulator
copyright 1996/1998 by Daniel Boris <dboris@comcast.net>
Developed by Daniel Boris, Andre de la Rocha and Arlindo Oliveira
This package is released under the
Clarified Artistic License (see COPYING)
Project Homepage
http://o2em.sourceforge.net
---------------------------------------------------------------------------
O2EM is an open source Odyssey2 / Videopac console emulator, created by
Daniel Boris in 1996. Since version 0.80 it has been developed by André de
la Rocha and since version 1.16 it has been developed by Arlindo M. de Oliveira.
This release includes the source code for O2EM v1.18 and binaries for
Windows. The sources probably can also be compiled under other platforms
that support the Allegro game library. The binary version for Linux/X11 and
DOS continues available just until the version 1.16.
With the Windows binary, the latest stable version of the Allegro DLL is also
included. To use the Linux version you must get the Allegro library for Linux
yourself and install it as root. The DOS version does not need additional
files.
O2EM is a command line based program, but there are several Windows frontends
you can use. The "official" one is O2EM Launcher, created by Heitor
Barcellos.
In order to build O2EM from its sources, you need either the MingW or Cygwin
packages on Windows, DJGPP on DOS and GCC on Linux. See the links below.
The latest version of O2EM can be found at http://o2em.sourceforge.net If you
want to send bug reports, or be part of the O2EM development, go to the O2EM
project page at SourceForge : http://sourceforge.net/projects/o2em/

The members of the OdysseyBR user group: for several bug reports, as
well for support in general.
-----------------------------------------------------------------------------
Building:
o2em depends on Allegro, for Ubuntu / Debian, run:
sudo apt-get install liballegro4-dev
-----------------------------------------------------------------------------
Quick Setup:
To get O2EM up and running quickly follow these steps:
1. Unzip the O2EM archive on your hard drive, that will create the necessary
standard directories: ROMS, BIOS and VOICE into the main directory O2EM118.
2. Download the bios ROM O2ROM.BIN (or G7400.BIN, or C52.BIN, or JOPAC.BIN)
and put it into BIOS directory.
3. Download one or more game ROMs, for example KCMUNCH.BIN for KC Munchkin and
put the ROM in ROMS directory.
4. From the O2EM118 directory type: o2em KCMUNCH.BIN to start the game.If wants
to play KC Munchkin with BIOS VP+, type: o2em KCMUNCH.BIN -g7400
---------------------------------------------------------------------------
Setup:
Before you can run O2EM you need a copy of the Odyssey2 or Videopac bios
ROM. For copyright reasons, this ROM image can not be included in this
archive. This ROM image is stored inside the 8048 processor and can be read
out with the appropriate equipment. The image should be 1024 bytes long and
should be in the BIOS directory into the main directory O2EM118.
You will also need cartridge images, but again for copyright reasons
these can not be provided. PLEASE DO NOT E-mail us asking for ROM images! All
messages asking for ROM images will be promptly deleted.
If you wish to use Voice emulation for games like KC's Krazy Chase.
Download the voice samples and unzip them into the VOICE directory
into the main directory O2EM118. There are two sets of voice samples,
mainsamp.zip which is the main voice samples and sidsamp.zip which are the
samples used by the game Sid the Spellbinder. You only need the Sid samples
if you want voice in that game.
---------------------------------------------------------------------------
Usage:
o2em <file> [options]
<file> = file to load with extension
options:
-help Help display
-wsize=n Window size used by the emulator (1=original, 2=double size, etc.)
-fullscreen Use full screen mode
-scanlines Enable scanlines use by the video emulation. Scanlines are a
feature that makes your display look like a TV screen.
-nosound Turn off sound emulation
-novoice Turn off voice emulation
-svolume=n Set sound volume (0-100)
-vvolume=n Set voice volume (0-100)
-debug Start the emulator in debug mode
-speed=n Relative speed (100 = original speed)
-nolimit Turn off speed limiter
-bios=file Set the file name and directory to find the console
bios. By default it looks for a file named o2rom.bin.
You can use a bios file from an Odyssey2, Videopac or
Videopac+ console. If you want to run VP+ games (in
VP+ mode) then you need a VP+ bios.
-romdir=path Set the directory to find the game rom. By default it
looks for path named .../roms
-biosdir=path Set the directory to find the console bios. By default it
looks for path named .../bios
-o2rom Start the emulator with Odyssey 2 bios (default for most games).
-c52 Start the emulator with french Odyssey 2 bios.
-g7400 Start the emulator with VP+ bios (default for detected VP+ only games).
-jopac Start the emulator with french VP+ bios.
-euro This option enables the use of European timing / 50Hz mode.
This option is usually not needed as most of the games that
really require this mode will be auto-detected.
-filter Enable the low-pass audio filter.
-scshot=file Set the screen shot file name or template. The screen shot
will be saved when you press the F8 key in the emulator.
The extension of the file you give will set the file type.
supported file types are bmp, pcx and tga. You can also give
a template to save several files, using the @ character.
Using an option like -scshot=dump@.bmp will save files with
names like dump00.bmp, dump01.bmp, etc. The pictures will
have a resolution of (320x240)*wsize.
-exrom Enable the use of an alternative ROM mapping for 4Kb games, to
support some games that use a special 3kb program rom/1kb data
ROM mode. The only known that use it are Four in 1 Row and
Musician and both are detected by their CRC and set correctly.
So this option is to be used only with games that are currently
unknown to O2EM. Do not enable it as default, as it will make
all the 4kb games that do not use this special mode crash.
-s0=QUIT,PAUSE,DEBUG,RESET,SCREENCAP,SAVE,LOAD,INJECT_HIGH
These option defines which keys are used for some of the system
keys, if you use this option, you have to enter all 8 keys, to
override the original keys (ESC,F1,F4,F5,F8,F2,F3,F6)
-s1=mode/keys Define stick 1 mode/keys
-s2=mode/keys Define stick 2 mode/keys
These options define how the console joysticks are emulated.
You can use a joystick connected to your computer or use
the keyboard. You can specify a mode number (compatible with
previous versions of O2EM) to disable the joystick emulation,
to select an actual joystick or to set a default keyboard
emulation mode :
0=Disable,
1=Default Right keys (arrows keys and right shift)
2=Default Left keys (W,S,A,D,SPACE)
3=Joystick
Example: -s1=1 -s2=3
You can also specify a list of 5 keyboard codes that will
be used to emulate the joystick, separated by comas
(without spaces), using this order : UP,DOWN,LEFT,RIGHT,FIRE.
The following codes are accepted (not case sensitive):
A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z,
0, 1, 2, 3, 4, 5, 6, 7, 8, 9,
0_PAD,1_PAD,2_PAD,3_PAD,4_PAD,5_PAD,6_PAD,7_PAD,8_PAD,9_PAD,
TILDE, MINUS, EQUALS, BACKSPACE, TAB, OPENBRACE, CLOSEBRACE,
ENTER, COLON, QUOTE, BACKSLASH, BACKSLASH2, COMMA, STOP,
SLASH, SPACE, INSERT, DEL, HOME, END, PGUP, PGDN, LEFT,
RIGHT, UP, DOWN, SLASH_PAD, ASTERISK, MINUS_PAD, PLUS_PAD,
DEL_PAD, ENTER_PAD, PRTSCR, PAUSE, ABNT_C1, YEN, KANA, AT,
CIRCUMFLEX, COLON2, KANJI, LSHIFT, RSHIFT, LCONTROL,
RCONTROL, ALT, ALTGR, LWIN, RWIN, MENU, SCRLOCK, NUMLOCK
Example: -s1=y,h,g,j,lcontrol -s2=8_PAD,5_PAD,4_PAD,6_PAD,RCONTROL
-scoreadr=address where the high-score is saved for specific rom
-scoretype=type how the high-score is saved for specific rom
-score=highscore default highscore on launch ("inject" with F6)
-scorefile=file file where the highscore is saved on exit
-savefile=file filename for save/load state
----------------------------------------------------------------------------
Default configuration file:
O2EM now can use a configuration file to set the default options, so you can
specify your preferred options in this file, instead of typing it every time
you execute the emulator. The command line options override the default
settings in the file. This file must be called o2em_def.cfg and be in the
same directory of O2EM118. This configuration file is a text file where you can
put the same options you would use when calling O2EM by the command line, but
each option must be in a different line and you should not precede it with
the - character. You can also put comment lines in the file, starting the
line with the # character. Example configuration file:
# My config
wsize=3
Euro
scanlines
filter
g7400
s1=8_pad,5_pad,4_pad,6_pad,rcontrol
You disable any option set in this file when you call O2EM in the command
line, passing the =0 parameter to the option. For this example configuration,
you could disable the filter option set in the file putting -filter=0 when
you call O2EM.
----------------------------------------------------------------------------
Controls:
Arrow keys + L = Default joystick 1 emulation
W,D,S,A + Space = Default joystick 2 emulation
ESC/F12 = Leave the emulator
F1 = Pause/Information
F2 = Save State-File
F3 = Load State-File
F4 = Enter debugger
F5 = Reset emulator (same as pressing the reset on the O2 keyboard)
F6 = Inject Highscore
F8 = Make a screen shot
Caps Lock = Enables/Disables the O2 keyboard input of the keys used by
joystick emulation
----------------------------------------------------------------------------
Debugger:
The emulator comes with a built in debugger that was used for development.
The debugger is not very polished and fairly incomplete but it can be useful
for single stepping through programs and watching their behavior.
H = display help
