The ROMs must be stored in a zip-file called "irobot.zip", which must be placed in the same directory as the executable.
The standard MAME ROM set is supported.
1998 and 2003 Versions
If you have a copy of the MAME ROM set, you will need to rename the ROMs to work with my original 1998 emulator.
The table to the below shows the ROM names as used in both MAME and my emulator.
Please note that the ROMs must be unzipped and placed in the same directory as the emulator.
