    New Emulator Updates hit the PS2 Homebrew Community as PS2 developer Jum drops version 2.0 of ColemPS2. The ColecoVision emulator comes with massive improvements as now its been coded to run off CD (making it compatible with OPL ) with an impressive 95% compatibility rate for the ColecoVision library. A huge thanks should go to "UniqueUserName" for drawingup new intrest in this emulator that has improved dramatically. View all the details in the tabs provided below.


    • ColemPS2 version 2.0
      By Jum 2002-2016

      An updated version of my PS2 port of the "COLEM" Colecovision emulator. This version is coded to run off of a CD. It has been tested with many game images and almost all run fine. I'd say about 95% of the games are playable.

    • Getting Started
      1. Find the Colecovision BIOS rom "coleco.rom", or one of the hacked Colecovision roms (the hacked versions normally bypass the irritating 12-second title screen when the Colecovision boots up).
      2. Find some Colecovision game images. Make sure that they are exactly 8K, 16K, 24K or 32K. (Some images have a 50-byte header added, and they don't work).
      3. Place the bios rom file in the same directory as "COLE_123.45" and the other files in the zip.
      4. Place your game roms in a sub-folder called ROMS.
      5. Use ImgBurn to burn a PS2 CD which contains these files and the ROMS folder.
      6. Boot the CD on your PS2.​

      The options screen allows you to choose between 3 controller "modes":

      4. Fixes to magnified sprite rendering
      5. Modified to work better in NTSC mode.
      6. Render 5th sprite (DigDug title screen)
      7. Fix to noise channel (colem 3.6 noise code)
      8. Fix to beamrider background grid (colour 0 issue)
      9. Fix to border / backdrop colour
      10. Turbo controller emulation

      12. PS2 dualshock key mapping to get all Coleco keypad numbers:
      - Dualshock L1, L2, R1, R2, TRAINGLE for Coleco 1, 2, 3, 4, 5
      - SQUARE + L1, L2, R1, R2, TRIANGLE for Coleco 6, 7, 8, 9, 0
      - SELECT for Coleco *
      - START for Coleco #
      13. PS2 video mode changed to 284x240
      - "Zooms" the playfield slightly
      - Reduces borders slightly
      - Borders needed for same look at CRT TV
      14. Use R3 to get to options menu​

    • Almost all Coleco roms should play fine except for these few:
      Choplifter & Sprite issue

      If you have problems with control/input, press R3 on the PS2 dualshock, and
      change the controller option to match the game.

      Also note that roms should be either 16k, 24k or 32k.
      (16384 bytes, 24576 bytes or 32768 bytes)

    • Credits
      ColemPS2 is (heavily) based on Marat Fayzullin's "Colem" "portable" Colecovision emulator source code, so thankful credits are due to Marat.

      Credits to the writers of the Colecovision tech docs, and the writers of the MESS Colecovision source code.

      Many thanks to madcow (UniqueUserName) for motivating me to update ColemPS2, and for all
      his testing, glitch reports, and feedback.

      Thanks to Guichi for the menu/select screen backdrop art. His name is off the bottom of the screen in NTSC mode.

      Greets to all psx devers and ps2 devers.

      - James Higgs (aka Jum)
