Nintendo

Game Boy Advance

TempGBA4PSP

TempGBA4PSP is the most recent GBA emulator for the PSP, and has superior compatibility with most problematic games (Golden Sun, for example).

GpSP

GpSP is an open-source Game Boy Advance emulator created by Exophase and is probably the best Gba emulator on the psp.

Game Boy / Color

MasterBoy 2.10 or RIN 1.32 or GeMP 3.3 Final

GeMP and RIN have some incompatibilities with later PSP models. GeMP is incompatible with GameCategories.

Famicom (NES) / Famicom Disc System 

NesterJ 1.13 beta2 or NesterJ AoEX

AoEX is based on NesterJ 1.12 Plus 0.61 RM, so it includes features like rewind mode, cheat codes support, rotated/mirrored screen, sepia palette, support to rare mappers (the pirate bootleg FF7 works on it), etc, but its compatibility is inferior to 1.13 beta2.

Super Famicom (SNES)

Snes9xTYL mecm Mod

SNES emulation isn't very good to begin with, but this is the fastest and most compatible emulator available right now.

Nintendo 64

DaedalusX64

Most games are unplayable, but there's a small amount of them that work really well with the right settings (Quest 64, for example).

Nintendo DS

DSonPSP

Probably the only ds emulator and is very experimental and support for it stopped a long time ago,and you can't a touch or second screen on psp properly (unless you flip the psp sideways), so it was a failure from the start.

Genesis / Sega CD 

PicoDrive 1.51b
