Anyway, what BoBo said in the other thread is correct - DreamSNES is currently the best SNES emulator for Dreamcast.
The following was posted on the DreamSNES homepage on Dec. 21:
"Numerous persons have mailed me asking for some kind of progress report on the next release. Well, since it's been rather many months since the last release, I figured I might deviate from my principles a little and actually give you one. All in the spirit of X-mas and so on...
Although we have all been doing other stuff, progress has not been nonexistent since the last release. The biggest endeavor has been getting the assembler CPU emulation core in place. While there's still bugs left, it does run at least some games properly. And it does improve speed by some percent at least.
A considerable amount of effort has also been made on moving the emulation of the sound CPU over to the ARM CPU on the Dreamcast. Unfortunately, it now looks like the ARM is too slow for this to be a feasible solution, being clocked at only a disappointing 2.8 MHz.
Other developments include a new input system, which removes the need to configure controller types. Suitable controller emulation will automatically be chosen based on what DC controllers are attached at the time being.
All in all, stuff are still happening, but there's still to much to do for another X-mas release to be possible. But fret not, I predict that we will find some other appropriate holiday to use. "
To be honest, I can't help but think that the 2.8MHz clock for the AICA ARM is a typo, since Saturn had a much faster sound CPU, and even the Genesis sound CPU runs at 3.58MHz...
i cant complain with dreamsnes, ive been playing Link to the Past off and on, and it is still VERY playable. I have beaten the third or fourth (cant remember off of the top of my head) dark world dungeon running at the regular speed with sound. IF you turn off sound you can play full speed, as someone else mentioned, but i think its just fine to play at 90% speed with sound.
