    Could this great emulator ever have prefect compatibility with SNES game besides the obvious Mario RPG which has that special chip which can't be emulated by the DS

    Probably not. It renders directly to the screen using the DS's 2D hardware, and as such it will always have some graphical glitches. A software renderer would get rid of graphical glitches but would slow it down horribly.

    SMRPG isn't the only one with a special coprocessor chip. See http://wiki.pocketheaven.com/SNES_games_with_special_chips for a more complete listing of games that won't run on any SNES emu for the DS.

    so a game like super metroid can never be emulated perfectly on the DS on any emulator?

    I don't see why not eventually, it's got no special chips or anything. You've got to give the emu coder a chance though. He's porting an emulator across to a system where he doesn't have the official SDK and it's not like you can just nip out to the shops to buy a book on coding for the DS. He's done a pretty amazing job in the little time he's been working on it. Perfect emulation will probably appear at some point, just be patient.

    I never knew there were so many FX/DSP games! Although I'm not sure Dungeon Master should be in there as it runs on a copier without a DSP upgrade or a DSP enabled cart plugged in.

    EDIT : Actually I was wrong about Dungeon Master, just tried loading it up on the SNES and it didn't run.

    Emulation may not be the best for some games, but has anyone tried to play it with the EZ Flash 3-in-1? The added 256 MB RAM really increases the speed.

    In theory, the extra RAM shouldn't really improve speed too much. It's a trade-off you see. Without the RAM, large roms have to constantly page in and out of memory, which causes slowdown. With RAM, you don't have to do that, but external RAM is slower to access than DS RAM by nature. Granted, you've got a 3in1 (fastest slot-2 RAM) while I have a Supercard (slowest slot-2 RAM) so that may play a role, but I haven't noticed any real improvement when using v0.6 Alpha as opposed to v0.5 Beta.

    8 bits to a byte. 256 Mbits = 32 MBytes. The 3in1 contains 256 Mbits (32 MBytes) of NOR flash, and 128 Mbits (16 MBytes) of RAM.
