https://github.com/cotodevel/SnemulDS Looks like it's making a comeback. v0.6 last update 10 days ago. Works better with single processor games. SnemulDS is an SNES emulator in .nds format. So emulating snes roms from the slot one cartridge without the need for a special flashcart (i.e. the supercard dstwo) that advertises snes emulation as a special feature. Any will do.
