More info on yoyofr, laxer3a and thunderZ’s Snes9x_TYL Super Nintendo emulator has surfaced on their website. This includes what is to come with the upcoming version (from their site):
“New version still on the way, coming soon ;-) Here's some things to know with current version issues :
– games freezing & mosaic mode : use software rendering modes (software accurate or software approx.). (Mario, Final Fantasy, Lufia, ...)
– no sound & game freezing, but emulator's menu still accessible : you have probably turn off sound and reactivated it after. This is not and cannot be supported, as in Zsnes or Snes9x on PC. When you turn off sound, the sound processor is not emulated anymore, so the sync between main cpu and sound cpu is lost for the snes. Another solution is to save your game using original snes saves (save IN the game, not using savestate). Then turn on sound in menu, reset the snes and load your game. Of course this can be done only in game that support saves (RPG, Zelda, Mario, ...) If you want to gain a little speed and be able to turn on sound later, used "sound emulated/no output" mode. Update coming soon, with new features and fixing the crash bugs.
– PSP sleep mode issue & memory stick corruption : current version has issues with sleep mode, so please don't use it. It doesn't resume well and moreover can corrupt some memory cards. If your memory card is corrupted, try to get the remaining data on your PC using a card reader and then format it.”
