These emulators are for use on CFW or LCFW. The latest and most stable/compatible emulators are at the top of the lists.

The specific emulator versions compatible with the Half-Byte Loader can be found listed on the official site. Emulators for OFW are meant to run on unmodified firmware, a list for that is also on the HBL forums.

Please note that some emulators may require BIOS files from the original machine, we cannot supply those files.

Fourth Generation

NEC PC Engine/TurboGrafx-16

The final product of xPCE 4 PSP, HuE is a huge update from its predecessor and emulates most PC Engine ROMs perfectly

Neo Geo

See "Neo Geo Compatible" under Arcade.

Sega Genesis/Megadrive and Sega CD

There's a button bind to change rendering engines. One is faster but not as visually-accurate, while one is more accurate but slower. In the majority of situations, the faster engine is still just fine, only some specific special effects need the accurate one now.

Super Nintendo (SNES)

Fullspeed on most games with some hacks, will even run Super Mario RPG and Star Fox properly. If a game seems to run slow at parts (and you know it wasn't slow like that on the original SNES), then go into the hacks menu and set it to show rendering passes. If it's more than 0 or 1, then try out some of the hacks, the palette write issue seems to be the most common. Settings are saved per-game, and if you ever change settings to where a game will no longer load (for example some games don't like some rendering engine settings), press SQUARE to override the game's settings with the default ones again.
  • Snes9xTYLmecm 11-27-09 MOD r26 -> DOWNLOAD
A viable alternative. See the above entry for info on speedhacks and settings.

Fifth Generation

The fifth generation is the physical limit of the PSP's emulation prowess. The PSP itself is a Seventh Generation handheld, (comparable in power to the PS2, a sixth generation console), making such emulation infeasible.

Atari Jaguar

It's not very fast.

Nintendo 64

Check the compatibility list.

Sega Saturn

You must obtain the SEGA Saturn BIOS yourself; a simple Google Search will turn that up. This emulator only works for a PSP 2000 or 3000, it needs the extra RAM.

Sony Playstation

The PSP includes native support for Playstation games, though POPSLoader may be required to get them working.

Virtual Boy

  • Red Dragon Experimental PSP 10/19/2007 -> DOWNLOAD
Compiled for CFW 1.5, has about an 85% VB ROM compatibility.

Note this is a proof of concept only. It is impossible to configure the inputs, making it unplayable.

Handhelds

Neo Geo Pocket/Color

An excellent multiconsole emulator that emulates the NES, GameBoy, WonderSwan, GameGear, Master System, NEOGEO Pocket, and Lynx
"Don't use the BIOS option for RACE!PSP. It breaks more things than it fixes e.g. Metal Slug 1st and 2nd Mission, Puyo Pop and Mini Puzzle Bobble all break when the emulator attempts to utilise the NGP BIOS. "
Regarded as the best Neo Geo Pocket EMU.

Nintendo DS

Nintendo Gameboy and Gameboy Color

Nintendo Gameboy Advance

Gameboy Advance emulation on the PSP is primarily based on Exophase's gPSP, which prided itself on quality and range. However, a few unofficial modders from Japan took it on themselves to add more features, resulting in a mess of variations of differing quality. The family tree has been a mess ever since.

We recommend takka's UO gpSP Kai.

Takka's famous unofficial Japanese version of gPSP, which has been the preferred fork for generations. Translated into multiple languages by DarkSpace. Slightly slower in some games, but retains 16:9 stretching and cheats. You may need to turn "Fake FAT" on to avoid crashes.
  • gPSP-J ~ 2012-06-16 -> DOWNLOAD - AUTHOR: anonymous
Based on gPSP v0.91. A new edition of the UO gPSP-kai emulator made by an anonymous Japanese coder, following from v3.1.
Bit more speed in some games, but some features were removed such as 16:9 fullscreen stretching support and cheats. The Kingdom Hearts intro plays without a freeze, so the player doesn't need to do the savestate/loadstate workaround. Also, Digimon Racing Link-connection check at startup works correctly and the game properly reaches the main menu instead of getting stuck at the intro screen.
If you experience crashes, you may need to turn "Fake FAT".
The emulator will start in the Japanese language. To switch to English:
  1. Select a ROM and press O.
  2. Press the HOME button.
  3. On the first menu go to the 5th option.
  4. On the next menu go to the last option and press > or < on the control panel.
  5. Exit gPSP-J and start it over again. gPSP-J will now work in English!
Fullscreen has been removed, but use these options to get as close as possible.
   Display mode: USER GU
   Magnification: 165%
   Bilinear Filter: On
The original by Exophase, with a greater focus on compatibility over features. This newest edition was signed by Dovahkiin, with quite a few bug fixes, to boot.

Sega Game Gear
