Bubble Bobble 83 as a TI83 Operating System

[Dwedit]

Here is a (very buggy) TI83 Operating System ROM consisting of Bubble Bobble. Only works in Tilem. I'd like to find out why it fails in other emulators.

No, you can't send this to your calc.

And here's source code to the tiny OS it uses which handles interrupts (poorly) and boots (poorly): minios.z80

It does sort of work in PTI. It doesn’t turn on the LCD, but when I enter the debugger, I see that the LCD memory contains the menu screen. However, it doesn’t seem to react to keypresses either.

Here’s a fast build of PTI that doesn’t check whether a file is a valid ROM image for 83s either, so any 256k file is assumed to be one:
