I would like somethink for sounds, music and Speech and an X-Copy version
about speech for example something like a Terminal Emulator II but easier to use for Speech Synth programming.
about music and sounds i would like an 80col tracker to create music for TI99, a similar game to the protracker on the amiga for example, better if supported by the mouse also.
Lot of us also have the SID Master card and would be very cool to have possibility to have a program to play the original .sid files.
about games I would like to see a good Billard game
...also a graphic copier like the Amiga X-Copy could be funny to see...
Not sure what you are looking for with respect to sound and speech, but the code for Barry Boone's SoundFX was published. You could easily record the specific sound bytes you wanted on a TI, then play them back, possibly from stored memory (SAMS, etc) if you were going to add them to a game, etc. I know I disassembled Barry's SoundFX code and converted it to a MDOS program. I added a few extra features. Playing the Gilligan's Island theme song in reverse sounded about like monks chanting.
Food for thought.
