MAME

MESS (Multiple Emulator Super System) is a multi-system emulator which emulates more than 400 computer systems, many of them from the good old days of the Home Computers. Among them are also a number of TI platforms:

• TI-99/2 (not working)
• TI-99/4, 50 Hz and 60 Hz
• TI-99/4A, 50 Hz and 60 Hz
• TI-99/4QI, 50 Hz and 60 Hz
• TI-99/8
• Geneve 9640

A number of peripherals are also emulated, ranging from various disk controllers (up to HFDC), to serial interfaces, USB interface, IDE interface, HSGPL, and also SGCPU.

I would be happy to see more people from the TI community helping to improve the TI emulation in MESS.

The emulator is currently available as version 0.153 pre-built for Windows systems, and as a source zip archive for all platforms. If you want to build MESS from source, do not forget to download the corresponding MAME source package first, unzip it, and unzip MESS over MAME. You get MAME from http://mamedev.org/. A good location for that is the MESS message board.

You can download and work on the MESS source codes, but MESS is not an open source project in the GPL sense. If you want to contribute, download the sources, and get in contact with the maintainers.
