Heres the readme!!!

Potemkin (Codename DaSH)
Experimental HLE PSP Emulator

Henrik Rydgård (aka ector)
[email protected] (ONLY developer questions and similar)

Released under the GPL since I got bored of fixing stupid bugs and adding functionality to my HLE-simulated PSP OS.

Features: (end-user point of view

- Plays Puzzle Bobble Pocket JAP
- Starts AI Go
- Runs numerous demos from the PSP SDK

Technical Features:
- Badly simulated PSP kernel
- No VFPU emulation
- Mounts ISOs and CSOs (no DAX!)
- Mounts Windows directories (no good UI yet for this)
- (FUTURE) Supports game-specific patching through UltraHLE-style INI file

HLE code structure:
Internal functions begin with __Kernel. These are called when multiple real HLE functions
share code, or when other code wants to affect the PSP kernel, such as loading modules, etc.

TODO:
* Timing system
* Investigate skinning sample
* Eventflags (Gradius, locoroco, etc)
* Proper sound
* Proper FPL (spongebob)
* DelayThread (bomberman)
* Investigate bad ISO reading
* Investigate raw sector reading (GTA for example)
* Remaining VFPU instructions, for katamari and PQ
* sceUtilitySaveData, MsgBox
* Memstick Detection (2001: [R4 08971050 ]: HLE: sceIoDevctl("mscmhc0:", 02025806, 00000000, 0, 09fbbca0, 4) (z_un_0897101c)
* Fake PSMF and MPEG
* Atrac using the dll
* ReferSemaStatus (outrun)
* VBlank interrupt
* Callbacks
* Real thread ready queue

Compatibility List:

Playable:
Pinball (breaks if I fix waitforvblank)
Puzzle Bobble Pocket (some graphics missing)
Puyo Puyo - Nearly perfect!
[none]

Ingame:
AI Go (AI hangs)

Title Screen / menus:
Frantix - crashes the emu while loading
Carol's Sudoku - title screen, waiting for callback? async io callback? (seems to work without)

Craps on the screen:
Koloomn - seems to run, but only shows blank screen
Wipeout Pure - Sector Reading
Namco Museum - Now Loading , DelayThread
Namco Museum Battle Collection - Now Loading , DelayThread

Me and My Katamari - DelayThread or Vblank interrupt

Outrun - PollSema, Sector Reading
GTA LCS - Sector Reading //SavedataInit, Wakeup

Monkey Ball - Thinks it's in Dev, Tries to read from host0: ! sceIoOpen 08a56000
Pocket Racers - Thinks it's in Dev, Tries to read from host0: ! test at 089c2a7c, read from 090F93B8

There is an auto-run option in settings!!

Its a multisystem project, which is mostly based on nintendo hardware. PSP does not have a 2nd CPU and if you examine the menu under system, the four entries have been converted to "PSP", which should be GBA, DS, PSP, GC.

Attached are some screenshots, which clearly show that it was a multisystem project that never really put more effort in the psp side but the nintendo machines. If some good coder can clean this up and get the PSP thing working efficiently, this is a good emu.

why in gods name did you release the SOURCE of this project onto a site filled with nooblets? release the freaking BINARY for god's sake!

How about downloading and opening the file and see that there is a binary in there >_>.

Actualy the PSP does have a second CPU in the unit (but all it's actions could be HLE). The ME is another mips r4000 based core.
