New Features
Version 2.6.1 (September 12 2010)
- Now clearing all RAM to zeros (Heist works)
- Now padding smaller ROMs with 0xFFs in LoadROM()
- Fixed Reset9918() to reset VDP completely (Boulder Dash and Frogger)

Installation
Unzip colempsp.zip into /PSP/GAME/ folder on the memory stick.
Please note that system ROM’s must reside in the same folder as EBOOT.PBP file, either uncompressed, or inside SYSTEM.ZIP. Game ROM’s may reside anywhere (the ROMS subdirectory is recommended, but not necessary).
Controls
ColEm PSP currently comes with the following default key mappings:
In-game:
| Analog stick | Joystick up/down/left/right |
| Directional pad | Joystick up/down/left/right |
| [ ] (square) | Joystick Left button |
| X (cross) | Joystick Right button |
| O (circle) | Joystick Blue button |
| ^ (triangle) | Joystick Purple button |
| R | Display the virtual keypad, for as long as the button is held |
| L + R | Return to emulator menu |
When the virtual keypad is on:
| Directional pad | select virtual button |
| [ ] (square) | press a virtual button |
Keyboard mappings can be modified for each game. By default, button configuration changes are not retained after a mapping is modified. To save changes, press [ ] (square) after desired mapping is configured.
Compiling
Source code for ColEm PSP is available via a Subversion (SVN) repository. To check out a particular version, run
svn co http://svn.akop.org/psp/tags/colem/version
where version is the version number. Note that for this to work, you need to have Subversion installed.
To compile, you will need zlib (svn://) and libpng (svn://). To enable zipped ROM support, #define MINIZIP.
