Revision as of 22:55, 11 April 2005
Status
Game is completable. There are occasonal minor graphical glitches.
Problematic places
- map_loadDataFromAvo() in map.cpp. These are plain calls to memcpy() so all read data is not endian safe and moreover it could read wrong size if sizeof(structure) is used in length calcualtion. All structures should be unwind, i,e, read element by element and FROM_LE_XX wraps applied.
- data_readData(). Same as above.
Bugs
- It hangs on "please wait" screen in EGA version when screen is completed or switched by code
- Keyboard input is buggy as some keypressed get ignored. Particularly noticeable when entering screen code
- When game calls delay() screen doesn't get redrawn. Noticeable at "please wait" screen and especially cutscenes (try screen #5 FTWKFEN)
- Demo doesn't handle last screen properly. It hangs instead of printing ordering info
Main and long-term goals
- Convert it to C++ classes. This should be done on per-file basis and keep in mind that we should make it to resemble original code al little as possible.
- Endianness fixes
File-specific tasks
gob.cpp
- Write proper game detection. (MD5-based?)
interp.cpp
- Since neither VGA nor CD versions have protection screen we may skip it in EGA version too
sound.cpp
- Has yet to be written from sound.asm
- Support Red Book audio in CD versions
text.cpp
- This file should be removed and is not currently required for compilation but we need to inspect which variables does it set and to which values and convert them to our Config Manager. We should support all video outputs and at least PC speaker and Adlib.
util.cpp
- Get rid of rand() and use RandomSource
video.cpp
- Implement pDrawLine function from the VGA driver (lvga.gdr) Is it ever used?
- Add support for other rendering modes (EGA/CGA/Hercules) lega.gdr, l360.gdr, lcga.gdr
