MAME TI 99-8 & TI 99-2 full usable download
I have put together a workable MAME TI 99-2 & TI 99-8 packages. Just download and execute the batch file in the MAME directory.
The 99-2 & the 99-8 never made it market for TI but they got fairly far along to the point of workable prototypes and even manuals (download manuals from http://ftp.whtech.com/datasheets%20and%20manuals/ ).
The 99-2 works fine as is. It only has 4k of memory, no sound and B/W. Bo sure to use only the disk in the DISK directory. The sectors are different than the standard TI .DSK files.
To access the disk use: OLD HEXBUS.101.SOMEFILE to save files use SAVE HEXBUS.101.SOMEFILE (somefile is your file name).
there is a small file on the DISK BASIC-proj.DSK (the batch auto loads this disk) named HELLO. To load type OLD HEXBUS.101.HELLO
In the batch file I kick off a text file that pops up next to the MAME screen with the 99-2 function keys and a vbs script that turns on the upper-case when the 99-2 starts and turns it of when the 99-2 ends. All this pertains to the 99-8.
What is different about the 99-8 is the requirements from the PC. A i5 or i7 is required to work fast enough. I have set the 99-8 to work with my i3 in the batch file by skipping 1/2 the frames with -frameskip 30. If you have a i5 or i7 you can reduce this or eliminate it.
Also, to keep the sound from stuttering I have set -audio_latency 34. If you have a faster machine, again, this can be changed of eliminated. I you have a PC slower than a i3, forget about it.
