@m45t3r, in the 2020 version of snes9xd -- which does indeed work a lot faster :partying_face: -- I've encountered two serious rendering issues:
In the game "Mighty Morphin Power Rangers - The Fighting Edition", when a match is started and the playing stage is rendered, the graphics get completely garbled in a glitch-like fashion -- making the game unplayable. Everything works (menus and all), except the gameplay itself due to this visual rendering bug. (The ROM is a fine dump -- I double-checked.)
The game "Batman Returns" crashes upong loading the music and graphics, right at the start -- the audio hangs and the emulator crashes. It seems like it gets bogged down trying to load/display something. (Again, the ROM is a fine dump.)
Figured out what was wrong: the "snesadvance.dat" speedhacks broke these two games. The workaround is to remove the entries for these games from "snesadvance.dat" (by editing the text file).
