For GP32-specific, there's:
Mill (Korean)
ASR (Korean)
Emulated full RPGs (not "adventure" or "action"), there's:
FF1 & FF2 - Wonderswan Colour (no sound, better graphics)
FF1-3 - NES (sound)
DW1-3 - Gameboy Colour
DW4 - NES
Chaos World - NES
Mother 1 - NES
FF Legends 1-3 - Gameboy Colour
7th Saga - SNES
Earthbound - SNES
Chrono Trigger - SNES
FF5 & FF6 - SNES
Romancing Saga 1-3 - SNES
For the SNES titles, they'll probably work on Frameskip 5 or 6 WITH sound because most turn-based games are very low in FPS. And I'd also like to mention:
Ogre Battle - SNES (Strategy RPG)
Tactics Ogre - SNES (Strategy RPG)
