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.
– Remove debug code
– Rewrite the logic for the scoll fog (render buffer clear colour). Each viewport can potentially have a scroll fog value so the logic of which value to pick wasn’t immediately clear. TLDR I think it picks the highest value starting from the lowest priority layers. This fixes the sky in daytona battle on the edge.
– Scroll fog is like a clear colour for the render target, but can be semi transparent as the tilegen layer can be shown underneath. I assumed that transprent polys would be drawn to the render target for transparent polys but unfortunately the logic does not work. So where else could it be drawn? Well with limited memory it must be draw to the buffer for opaque polys, which means this render target is also blended.
– Implement correct « round to nearest » mode On PowerPC round to nearest ties to even, not away from zero Also implement correct behavior for ppc_fresx
– Fixes « tips to win » sequence in Daytona 2 BOTE
– Rewrite the renderer a bit to spit out the finished graphics from the 3d chip on separate buffers. One buffer is for opaque pixels, and 2 more for translucent pixels. Before the frame was composited on the back buffer, which meant the tilegen had to have been drawn first. This way the images are now totally independant of the tilegen chip so can be drawn as soon as the register write 0xC is written to the tilegen.
– Some games update the tilegen after the ping_ping bit has flipped at 66% of the frame, so we need to split the tilegen drawing up into two stages to get some effects to work. So having the tilegen draw independantly of the 3d chip can make this happen.
– Misc fixes
A noter qu’un nouveau fork ajoutant le support du Sinden est dispo ici.
Ajout:
– correction des musiques dans sega rally 2 (mix)
– correction musique 1er niveau 2joueurs (la cave rouge) dans vf3 (pas sûr de la modif, et donc cela peut éventuellement entrainer d’autre problèmes sonore sur d’autre jeux).
