Specific system information
Adding games
When not using .rpk files, it is recommended to use the "software list" for ti99, as MAME is very picky with this system's romset.
The file ti99_cart.xml
located in the \bios\mame\hash
folder will help you determine the right game roms to use.

The zip file must be named after the software name tag (e.g. advent.zip
).
The content of the zip must contain the exact bin file accepted by mame visible after the rom name tag (e.g. phm3041g3.bin
)
