Le premier émulateur de Sega Model 3 créé par Bart Trzynadlowski, Ville Linde et Stefano Teso dans sa version de développement (voir ici ou là) [source].

 

 
Les changements:
 
Le système de mise à jour passe de SVN à GIT, du coup le nom des versions changent, par simplicité j’utiliserai un système par date de release plus compréhensible que le par défaut de GIT.
 
– Update README.md: copyright dates.
– Model3.cpp: Comment describing scan line timing.
– Ping-pong flip timing depends of the value of tilegen register 0x08 Also make the debugger display 16 bytes per line when using the « listmemory » command. Mirrored system registers can now be watched
– Update rules file. Not tested this but hopefully it should work
– Emulate the entire tilegen chip in a GLSL shader. (This is now possible with opengl 3+). The tilegen drawing was emulated on the CPU, but was one of the most expensive functions in the emulator according to a profiler. On a modern GPU it’s pretty much free, because a GPU is a massive SIMD monster.
– Tilegen shaders are mapped to uniforms, and the vram and palette are mapped to two textures.
– TODO rip out the redundant code in the tilegen class. We don’t need to pre-calculate palettes anymore. etc
– The tilegen code supports has a start/end line so we can emulate as many lines as we want in a chunk, which will come in later as some games update the tilegen immediately after the ping_pong bit has flipped ~ 66% of the frame.
– The scud rolling start tilegen bug is probably actually a bug in the original h/w implementation, that ends up looking correct on original h/w but not for us. Need hardware testing to confirm what it’s actually doing.
– Misc fixes
 
A noter qu’un nouveau fork ajoutant le support du Sinden est dispo ici.
