| 2026-03-12: Cocopedia.com is now using a new caching system that should make things faster. Please let me know if you encounter any new issues.
2026-03-15: MediaWiki has been reinstalled and the old database and files restored. It was pretty clogged up from being upgraded so many times since 2004. I am also testing out Cloudflare to see if it can prevent the 'bot assaults that took the site down last year. OS-9 Al (talk) 21:20, 15 March 2026 (EDT)) |
MAME
MAME (originally an acronym of Multiple Arcade Machine Emulator) is a free and open-source emulator designed to recreate the hardware of arcade game systems in software on modern personal computers and other platforms.
As such, it can be used to emulate most - if not all - CoCo variants, including clones like the Prologica CP-400
Installation
[edit | edit source]Windows
[edit | edit source]The installer can be downloaded from the official MAME site
macOS
[edit | edit source]Linux
[edit | edit source]Setup
[edit | edit source]In order to run MAME, you will need the ROMs from the computer being emulated. They can be found in the TRS-80 Color Computer Archive, under the MESS ROMs section
Once downloaded, copy the ZIP file containing the .rom files to the \roms folder in your MAME installation.
Command line parameters
[edit | edit source]MAME can be started and the emulated computer configured from the command line.
- mame64 [machine] [media] [software] [options]
Machine is the name of the computer to be emulated. Some CoCo related options are: coco, coco2, coco2b, coco3, dragon, dragon64, cp400, cp400c2, lzcolor64, mx1600 and cd6809
The remaining parameters are used to determine the configuration of the emulated computer. Some examples are:
mame64.exe coco -ramsize 16K -window -confirm_quit
will emulate a CoCo 1, with 16 KB of RAM, start the emulation in a window (instead of full screen), and prompt for confirmation before quitting.
mame64.exe coco2 -ramsize 32K -ext games_master -nowindow -confirm_quit -skip_gameinfo
will emulate a CoCo 2, with 32 KB of RAM and a Game Master Cart, start the emulation full screen, prompt for confirmation before quitting and skip the initial screen showing the computer's configuration.
mame64.exe coco3 -ramsize 512K -ext multi -ext:multi:slot3 ssc -flop1 "Documents\DSKS\SAMPLE.DSK" -window -nomaximize
will emulate a CoCo 3, with 512 KB of RAM, a MPI with the Speech/Sound Cartridge in slot 3, and the disk image "SAMPLE.DSK" from the specified path, mounted in drive 0. It will start the emulation in a non-maximized window.
It should be noticed that if a disk ROM is available, and nothing is loaded in the cartridge slot (or in slot 4 of the MPI), a floppy drive controller will be automatically loaded.
