actually i have found CS1er does not really work. it will make an audio file, but when loaded into the ti99/4a it does says something about a error in data
You'll need a hardware device like Gram KRACKER for running ROM files. If you are referring to the disk versions of the same, then you'll require 32K memory expansion. Trying to load assembly games from tape is possible, but it's quite a task.
I would definetely go for a nanoPEB (CF7+), it will make your task a lot easier. Check here:

so there's no way to turn simple tape images into audio? i'm not worried about disk programs so much though. or is there a command besides "OLD CS1" i should be using to load these 2 minute long audio files?
