lolSnes is a project Mega-Mario started two years ago. He wanted to make a SNES emulator for the DS, that could render most sane games without glitches. So far, Super Mario World is playable, to some extent.

What is currently supported:

* CPU — 99% (all opcodes emulated; may miss a few unimportant bits about timing)
* PPU — ~40% (mode 1 BGs, OBJs, mosaic, master brightness, giant kludge for BG3 prio)
* SPC700 — 80% (most useful opcodes implemented, CPU/SPC I/O, timers)
* DSP — 0% (yep, no sound)
* SRAM with auto-saving
