How can I open Game.com games with MAME?

[OmegaOmega]

Hello everyone. I'm trying to (and failing to) configure SimpleLauncher to open Game.com games using MAME. I tried to use Game.Com MAME's parameters, tried to adapt the Mattel Aquarius instructions, but didn't managed to make it work. I tried the parameters>

gamecom -rompath "E:\MAME\ROMs;E:\No-Intro\Tiger - Game.com"
gamecom -rompath "E:\MAME\ROMs;E:\No-Intro\Tiger - Game.com" -cart1
-rompath "E:\MAME\ROMs;E:\No-Intro\Tiger - Game.com" gamecom`

All of them presented errors, detailed in the following log
error_user.log

What I am doing wrong here?

Thanks for reporting this, and sorry for the trouble. I was able to reproduce the problem and find the exact cause: it is the ROM set, not the parameters. The parameters you tried were correct for MAME, but Simple Launcher launches MAME systems in "software list mode" — your parameters go first and the game is appended as a bare name (no path, no extension), like:

mame.exe -rompath "..." gamecom -cart1 "Tetris (USA)"

MAME then resolves "Tetris (USA)" through rompath — which only works if the game files follow the MAME naming convention. No-Intro dumps don't match, so MAME couldn't find the files (that's the errors in your log).

Detailed step-by-step instructions

1. Download a MAME-compatible ROM set

Go to the PleasureDome website:

• Download "Software List ROMs (split)"
• Inside it, grab the gamecom folder
• Keep the files in that folder with their original names (MAME convention)

2. Download MAME BIOS/device files

Also from the PleasureDome site (or your MAME ROM set), get the MAME BIOS/devices files and keep them in a folder like G:\MAME\MAME Bios Devices. The gamecom machine needs the BIOS files to boot.

3. Create the system in Simple Launcher

Setting	Value
System Name	Tiger Game.com
System Folder	the folder where you extracted the gamecom files (e.g., G:\ROMs\Tiger Game.com)
Extension to Search in the System Folder	zip
Extract File Before Launch?	false
Group Files by Folder	false

4. Configure the emulator

Setting	Value
Emulator Name	MAME
Emulator Path	e.g., G:\MAME\mame.exe
Emulator Parameters	-window -rompath "G:\MAME\MAME Bios Devices;G:\MAME\MAME Roms;%SYSTEMFOLDER%" gamecom -cart1

Points worth noting:

• -window keeps MAME in windowed mode (remove it if you want fullscreen).
• The MAME BIOS/devices folder must come first in rompath so the gamecom BIOS is found.
• %SYSTEMFOLDER% is a Simple Launcher placeholder that points to the system folder you configured — no need to hardcode it.
• -cart1 is the cartridge slot of the gamecom machine; Simple Launcher automatically appends the game name there.
• No manual -rompath for the game folder is needed — Simple Launcher also auto-injects your system folder into mame.ini, but keeping %SYSTEMFOLDER% in the parameters makes it explicit and safe.

5. Launch

Select a game and launch — MAME should now find both the BIOS and the game through rompath.

This configuration has been verified as working and was added to the parameters wiki in the new "Tiger Game.com" section.

Ensure the file "gamecom.zip" is present inside "bios path" or inside "rom path".

You need to use roms that follow mame filename convention (Download from PleasureDome website). You can NOT use No-Intro filename convention.
