This adds optional EPX scaling and 640x480 resolution for
LucasArts Macintosh games other than Indy3 and Loom.
This includes:
* Monkey Island 1
* Monkey Island 2
* Indy4
* Day of the Tentacle
* Sam&Max
* Full Throttle
* The Dig
In doing this, I reverted the ugly code which previously offset
the game screen 20 pixels below (to create an internal 320x240
buffer, instead of 320x200). Instead of just offsetting mouse
coordinates and the final screen texture, I used to offset the
in-engine graphics elements. Ew.
This ensures flawless savegame compatibility between old and
new, without touching anything.
I reviewed what I was comfortable with; this change is not complete
(and I didn't review the HE workarounds at all), but it's still an
improvement.
I may need to update the Enhancement page on the wiki with these
changes...
There are so many workarounds where we either want to make sure it's not
the "Ultimate Talkie" version or that it is, that it's much nicer to
have a feature flag than having to strcmp() the variant.
vm.slot[] only has NUM_SCRIPT_SLOT slots; don't dereference it with
_currentScript when _currentScript has the special 0xFF value (which is
always bigger than NUM_SCRIPT_SLOT). Its content was already unused in
that case, anyway.
Found with UBSan while calling `room 33` in the debugger in MI1.
('I can't reach it" when using reservations terminal in airports)
There was one call to resetSentence() missing. It its the same in v1 and v2. There are 4 calls to this function in the whole code, we did have 3 of these...
I didn't check v0, since I don't have it.
The Mac version only shows a copy protection screen if you explicitly
ask for it, and the unofficial talkie version doesn't show one ever.
Therefore there is no reason to trigger the virtual keyboard.
Force correct width value for room 64 (book of maps) in Indy3. This
works around the wrong value stored in the data files of a specific
version of the game (DOS/EGA v1.0, according to scumm-md5.txt).
Previously, we had a couple of arrays of size N (where N = number of
resource types), one for each attribute of a resource type (such as as
the number of resources of that type.
Now, we have one array of size N, whose elements are a record
aggregating all the attributes of each resource type.
MKID_BE relied on unspecified behavior of the C++ compiler,
and as such was always a bit unsafe. The new MKTAG macro
is slightly less elegant, but does no longer depend on the
behavior of the compiler.
Inspired by FFmpeg, which has an almost identical macro.
This commit should fix at least the following bugs/feature requests: #1032859, #1252088, #1055391, #1315968, #1315938, #1742106, #812891.
The FM-Towns version of Scumm games use a mixed graphics mode with 2 layers (one with 32767 colors and one with 16 colors). Among other things I have added a screen output class which emulates this dual layer approach which allows specific hardware effects like enabling and disabling layers (e.g. in the voodoo priestess scene in MI1).
Old savegames (saved before this update) will load, but you’ll encounter palette glitches in the verb/inventory screen, since the 16 color palette for layer 2 is not contained in your savegame. This will be true at least for version 5 games. Certain scene change actions (which require the verb/inventory part to be redrawn) might correct this (e.g. try looking at the treasure map in MI1 and closing it). Version 3 games should be okay, since they use a static text palette which is never changed and which will be reset after loading a savegame.
This update requires a USE_RGB_COLORS setting for proper operation. 8 bit users will get a warning that they’ll have to expect palette glitches . Apart from that the engine in 8 bit mode should not only still work okay, but also benefit from some of the other (non palette related) improvements (e.g. bug #1032859 should be fixed even in 8 bit mode).
Japanese font drawing hasn’t been improved much yet. This will be a separate task.
