Just wanted to post the first comment.

Any ideas when the 89 version will be released?

forgive my ignorance, but what exactly is a Chip8/SChip8 and why does it need to be emulated?

Chip8/schip8 is described in chiplib.txt in the chiplib zipfiles, but I will explain it here so people reading this will know before they download it. Chip8 was a computer system used in the 1970's to run early games such as pong. It had a 64x32 monochrome screen, and an instruction set designed for game programming. In the early 90's someone wrote a chip8 emulator for HP48. Soon after that, a few updates to the chip8 language were made and the new version was called Super chip8, or SChip8. SChip8 was a superset of the chip8 language, and featured scrolling and the option to use a 128x64 screen instead of the standard 64x32. This chip8/schip8 emulator can run all programs written for the original system and the hp48 emulator. Again, you can find more information about this in the chiplib.txt file included with the distribution zipfiles.

ok thanks that makes sense.

Any possibility that in future versions of this prog you could create a small key redefinition program. I only suggest this after having used Chip8 on the 83, where the key pad really sucks. I see that the 92+ has a different key mapping, but come on, the calcs already have arrow keys.

I have been planning on doing that. It would be pretty easy, I coded it to allow that. I think I'm going to make an on-calc chiplib setup program with things like change speed and remap keys. Thank you for the suggestion though, and please give me any more suggestions you have.

I think that this is a great idea. I enjoyed the Chip8 Emulator for the TI-85. Can't wait for the 89 version...
