![]() On both PPUs the games work as expected, but the code is wrong. Lines 17 activate additional loops, for old and new PPUs. Since I'm unable to advance, here's the patch for FCEUX:Īnd here's the modified PPU.cpp file for quick reference: Corruption is resulting visibly in crashing when it tries to save to config or changing a ROM (maybe more), and it's caused exactly by additional PPU loops/scanlines. But I don't know how to properly incorporate that info into code. There's info that actual Dendy PPU does nothing after scanline 240, but all the rest elements keep running, resulting in known timings. But when I add PPU loops (scanlines) to match Dendy's, something gets corrupted in the code, though the very Dendy mode was reported to be quite accurate (for a start). I added this, with extensive help from DoomGuard and Eugene.S.
