It's a variation of Fushigi no Dungeon 2 - Furai no Shiren, actually day 2 of 4 in the series.

It's only emulated in 1 German custom version of SNES9x, Snes9XW_SE2_K6. Having never played through the entire series, I can't really help you out any more than that, except that you need to use that emulator. Hopefully this will help out with BS-X emulation as a whole, or at least get it emulated in the 'big' emulators.
