For documentation on fMSX PSP, see README.md.

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)
  • Implemented SCREEN2 table address masking, thanks to Daniel Bienvenu
  • New save file format – not compatible with previous version

Installation

Unzip colempsp.zip into /PSP/GAME/ folder on the memory stick.

System ROM’s must reside in the same folder as EBOOT.PBP file, either uncompressed, or inside SYSTEM.ZIP. Game ROM’s can reside anywhere (the ROMS subdirectory is recommended, but not necessary).

Controls

During emulation:

PSP controls Emulated controls
D-pad up/down/left/right Joystick up/down/left/right
Analog stick up/down/left/right Joystick up/down/left/right
[ ] (square) Joystick Left button
X (cross) Joystick Right button
O (circle) Joystick Blue button
^ (triangle) Joystick Purple button
[R] Show virtual keypad
[L] + [R] Return to emulator menu

When the virtual keypad is on:

PSP controls Function
Directional pad select key
[ ] (square) press key
O (circle) hold down/release key
^ (triangle) release all held keys

Only certain keys can be held down.

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

To compile, ensure that zlib and libpng are installed, and run make:

make -f ColEm.mak

To enable zipped ROM support, #define MINIZIP in the makefile.
