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
- 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.
Since version 0.162, MESS is an integral part of MAME, the Multi-Arcade Machine Emulator.
The emulator is currently available as version 0.172 pre-built for Windows systems, and as a source zip archive for all platforms.
You can download and work on the MAME source codes, since all MAME components have been relicenced under an open-source licence (BSD or GPL). If you want to contribute, you should get in contact with the maintainers, though. A good location for that is the MESS message board.
I would be happy to see more people from the TI community helping to improve the TI emulation in MESS.
