Filippos Karapetis d61c5ae529 SCI: make g_base_opcode_formats and SciOpcodes a bit more readable 2012-07-04 11:57:40 +03:00
Filippos Karapetis 20b6770808 SCI: Change the program counter (PC) to be a 32-bit variable 
This is needed for future support of large SCI3 scripts. The program
counter is isolated and does not interfere with other parts of the VM,
plus it does not get stored in saved games, so it's pretty straightforward
to convert

Filippos Karapetis 2b50824133 SCI: Add setter/getter methods to reg_t's 
No functionality change has been made with this commit. This avoids
setting and getting the reg_t members directly, and is the basis of any
future work on large SCI3 scripts (larger than 64KB)

md5 cc074b013f SCI: Refactored and cleaned up the VM call stack handling code 
- Removed the CallsStruct intermediate stack. Calls are inserted directly
in the execution stack
- Added a constructor for the ExecStack struct and removed
add_exec_stack_varselector() and add_exec_stack_entry()

Filippos Karapetis 3c82b6578f Now that EngineState is not deleted when loading games, we can move some more state-related variables to it, and remove several FIXME's about non-const global variables. Also, the entries in the data stack are now deleted when loading (fixes a memory leak - thanks to digitall for this).

 2010-05-29 23:56:37 +00:00
Filippos Karapetis 67de5b1bd3 Mass renaming of selector-related functions, and removed some defines which were just cloaking functions with a different name 
- GET_SEL32 -> readSelector
- GET_SEL32V -> readSelectorValue
- PUT_SEL32 -> writeSelector
- PUT_SEL32V -> writeSelectorValue
Also, changed some selector-related function names and variables to CamelCase

 2010-05-19 07:25:06 +00:00
Filippos Karapetis f3892a506b - Removed the wrapper kalloc, kmem and kfree functions. Now, the associated Segment manager functions allocateHunkEntry, getHunkPointer and freeHunkEntry are used directly (which are more descriptive, anyway) 
- Replaced the GET_SEGMENT macro by a method of the segment manager
- Removed the unused reference to the created hunk in allocateHunkEntry(), only the reg_t reference to it is returned now

Matthew Hoops 3dda73d9a2 Add initial support for KQ6 Mac. Wrapper functions for read/writing to pointers are now used (found in util.*) for code that has different endianness in SCI1.1+ Mac games. Add support for Mac 'snd ' and 'CURS' resources. QFG1 Mac is not yet playable due to script compression.

Filippos Karapetis 887ca3145e Initial implementation of text drawing for SCI2 (it's a hack for now, done the "SCI0-SCI11" way, and text splitting is wrong...)

Matthew Hoops d883b6215f Detect whether to use the modified SCI2 or SCI2.1 kernel table based on the kDoSound call used in Sound::play(), which fixes at least my version of KQ7 - probably others. The kernel table initialization now occurs after the script signatures are adjusted as we need it adjusted before checking through Sound::play for the kDoSound call.
