Nintendo Consoles
Below you will find PSP emulators for all Nintendo consoles, This includes NES, SNES, Nintendo 64, Gameboy, Gameboy Colour and Gameboy Advance.
NES
NesterJ v1.13 Beta 2 / 347kb / Rated: 9.5/10 / DOWNLOAD
This is by far the best NES emulator for PSP, It loads just about any game, so worth a try!
FCEU-PSP V0.1 / 333KB / Rated: 8.0/10 / DOWNLOAD
Another NES Emulator for PSP, A port of the famouse fceux emulator for windows, not as good as NesterJ but could surprise you.
SNES
Snes9xTYL v0.4.2 mecm mod R19 / 2.4mb / Rated: 9.0/10 / DOWNLOAD
A mod of the original by wololo.net user "173210", the best SNES emu available#
Snes9xTYL v0.4.2 ME / 2.3MB / Rated: 8.5/10 / DOWNLOAD
Noth to be confused with the above emulator, this is the original by "yoyofr", some still prefer it to the better one.
Snes9x Euphoria R5 beta 3 / 5.1MB / Rated: 7.0/10 / DOWNLOAD
This emulator has good compatibility but is terribly glitchy.
Snes9x PSP v0.02 / 388kb / Rated: 6.0/10 / DOWNLOAD
Well outdated now, its very slow and not worth the trouble.
Nintendo 64
DaedalusX64 r1771 / 814kb / Rated: 8.0/10 / DOWNLOAD
DaedalusX64 just goes to show that even with a measly 333MHz CPU and 32MB of RAM, That Nintendo 64 emulation is possible on crummy specs if you put your mind to it, true many roms crash and dont boot but we have calculated that Daedalus has an 77.3110% boot rate, and a 61.9344% Playability Rate (calculations by Zix), This current version are the beta revs and so can be unstable however they offer better compatibility, if you look just below you can get the latest stable release.
DaedalusX64 Beta 3 Update / 673kb / Rated: 7.5/10 / DOWNLOAD
Less compatibility than the above but much more stable
daedalus-psp r14 / 2.05mb / Rated: 6.0/10 / DOWNLOAD
The first attempt at N64 emulation on PSP by developer "StrmnNrmn" runs about 30 games in total.
Gameboy & Gameboy Color
Homers Rin v3.2 / 623kb / Rated: 10.0/10 / DOWNLOAD
Undoubtably the best Gameboy Color emu out there for PSP, Its compatible with almost every title there is, infact we havent found one that does not work yet!
GNUBOY / 992kb / Rated: 09.0/10 / DOWNLOAD
A very popular emulator across multiple platforms, and a very good reason, its reliable and has a very high CR.
Rin v1.32 / 192kb / Rated: 08.0/10 / DOWNLOAD
The original version of the above emu although is inferior in every way, but still good!
GeMP v3.3 / 3.25mb / Rated: 07.5/10 / DOWNLOAD
An older GB/GBC emu for PSP that lacks bite and style.
Spiceboy r0 / 321kb / Rated: 07.0/10 / DOWNLOAD
Much the same as GeMP!
Gameboy Advance
gpSP Kai v3.2 Test 8 / 1.0mb / Rated: 09.5/10 / DOWNLOAD
The best on the market GBA emu for PSP, It emulates the GBA to a platinum standart, there are later versions of this emu but they lose some compatibility and are very buggy, this is the best version.
gpSPJ 091009 / 772kb / Rated: 09.5 / DOWNLOAD
Same as above only coded by a Japanese developer, its a little trickier to use though.
PSPVBA v1.2.4 / 1.27mb / Rated: 06.0/10 / DOWNLOAD
An earlier GBA emulator, that lacks speed and and a good CR.
VBAPSP v0.4 / 268kb / Rated: 05.0/10 / DOWNLOAD
The PSP worlds first attempt at a GBA emu back in 2006, but is incredibly slow, it took us nearly 30 mins to finish 1 race in Mario Kart.
NOTE: You will require a GBA Bios to run ALL GBA emulators to get one click on the link below and place the .bin file in the same folder as the EBOOT.PBP
Nintendo DS
DSONPSP BETA 7 / 220kb / Rated: 4.5/10 / DOWNLOAD
Unfortunatley this is as good as it gets for DS emulation on PSP, Its very slow and most games just about make it to the menu, although its intentions are more homebrew based, allowing you to run ds homebrew on PSP, although still pretty slowly.
