DeSmuME PSP Unofficial Useless Edition - Nintendo DS Emulator for the PSP

August 13th, 2007, 21:46 Posted By: Sektor

This is a painfully slow Nintendo DS emulator for Sony PSP. It's completely useless for playing games and unless you are a coder or just want to show off a DS game running on PSP at a few frames per second, don't even bother.

I made some minor changes to SofiyaCat's release:

Made sound optional
Added controls
Enabled FPS counter
Forced PSP CPU to 333Mhz
Added exit callback

It would require a major rewrite to get over 20 FPS and someone with much more skill, knowledge and time than I have.

Controls:

CIRCLE = A
CROSS = B
SELECT = Select
START = Start
DOWN = Right
UP = Left
RIGHT = Up
LEFT = Down
RTRIGGER = R / toggle touch
LTRIGGER = L
TRIANGLE = X
SQUARE = Y

Analog nub for moving touch position but I didn't bother to add a cursor. The Table Hockey Tech Demo has a cursor built in, so you can "play" it at around 3 FPS.

1.5 firmware:
Copy __SCE__DeSmuME_Useless and %__SCE__DeSmuME_Useless to ms0:/psp/game

3.x M33 firmware:
Copy DesmuME_Useless folder to ms0:/psp/game

NDS file must be named test.nds and in the same folder as eboot.pbp
You don't need any bios files.

Credits:
YopYop156, evilynux and DeSmuME team for creating this DS emulator
SofiyaCat/NekoMiMi for porting DeSmuME to Sony PSP
Everyone who contributed to the PSP toolchain/libs and anyone else I forgot
Sektor for creating the Useless Edition fork (modified main.c and ctrlssdl.c)

Compatibility listing here. Many games won't even start and the ones that do start take minutes to load. It's too slow to be any fun.
