A bit back I had these MAME/MESS packages posted on ti99resources.wordpress.com/ but decided with the limited space I have on that website to just concentrate on the TI-99/4 and TI-99/4a. So I posted them to an Atariage thread. But since things, over time, tend to get lost in those threads I'm re-posting them here with updates.
The .zip files come with everything you need to get the MAME/MESS emulator up and going except the current MAME/MESS. The emulator has been tested with MAME/MESS .235 and works down to version .225. get MAME here: https://www.mamedev.org/release.html and MESS here: https://messui.1emulation.com/ MESS is just MAME with the top menus put back.
I have the ROMS, CFGs and INIs in a MESS directory you will need to copy into your MAME/MESS so that the emulators will work. Be sure to keep the name of the MAME/MESS directory as MESS so that the execution batch file will work.
The emulated computers:
Tomy Tutor - Cassette and cartridge only.
Myarc Geneve 9640 - I have it booting into 2 hard drives. There is a lot more related files in other hard drives in archive.
Myarc MyXBII - also boots to a hard drive.
P-Card - Boots a boot floppy. Be sure to have the switch for the P-Card turned on in the switches. Only use the disk created to the p-card I have included. others may not work.
TI-99/8 - Boots to floppy. Only use the blank SSSD & DSSD disk I have included as others may not work. This is a resource intensive emulator with using the Hexbus; I5 or better.
TI-99/2 - Cassette only. Stick with the way I have it set up & don't use the MAME/MESS configurations of the Hexbus & the 32k memory expansion. Both I have had issues with errors on the 99/2. After all, who needs more than 4k anyway.
So here you go, have fun. HLO
