Are there any FPS that work on the Dingoo? I don't have high hopes for any on the SNES (most of which were pretty terrible anyway), but there were some decent ones on the Genesis and the GBA. Do any of them work at a decent speed/limited graphical issues?
For reference, I'll give a list of all the FPS games I know of for consoles the Dingoo can emulate:
GBA
Doom
Doom II
007: Nightfire
Back Track
Wolfenstein 3D
Dark Arena
Ecks vs Server
Ice Nine
Serious Sam (forgot the subtitle)
Duke Nukem Advance
(On the emulator on my PSP, Doom II, Ice Nine, and Duke Nukem Advance were unplayably slow and jerky, but the rest ran okay.
SNES
Wolfenstein 3D
Doom
(These were both terrible; I'm including them for reference only)
Sega Genesis
Blood Shot
Zero Tolerance
Duke Nukem 3D (Yes, there's a port of Duke Nukem 3D for the Genesis. Those wacky Brazillians)
Gameboy
Faceball 2000
Also, how hard would it be to natively port Doom to the Dingoo? I know you can run it on other MP4 players with Rockbox, so it shouldn't be that hard to get it on this device.
