That ROM image from my MP2100 works great under the Mac OS X version of the emulator.
If the source were available I'd be
more than happy to port it! But ROM's would be about as problematical as the TI calculators.
Unlike with the TI calculator, where I was facing needing to spend $130 + VAT for a calculator I had no use for so I could suck its ROM to continue porting, I had previously sucked my MP2100.
