I had added a feature to allow switching the main ROM but it broke the virtual cassette support. Virtual cassette I/O was more important, since that's how you get files in and out, so I had to revert.
I fixed the bug and re-enabled the feature. So you can now switch between the M100 and T102 ROM, and the cassette file i.o works fine. The only (good) reason I know for switching between the two ROMs is getting Analyst option ROM to work. It only works on the M100 ROM. -- John.
