Hi folks,

You might be interested in this (very preliminary) attempt to create a comprehensive test suite for IIe emulators. The idea is to pick up where Klaus Dormann's 6502 tests leave off.

Right now the high RAM ("language card"-like functionality), auxmem, and softswitch tests are mostly done, and pretty useful. After that it goes into a set of color tests where it generates identical color patterns in two different ways, so you can compare them. (Some jumping of margins is expected).

I intend to eventually add tests that the floating bus is reading the correct RAM locations on every cycle, and that the vertical blanking signal is cycle-accurate.

Any other bugs people point out to the IIe functionality in OpenEmulator are likely to become tests here too.

Hopefully this helps raise the bar for all IIe emulators out there. Although there are no serious problems, none of them currently pass all the language card functionality tests (except OpenEmulator, natch!).

Enjoy,

Zellyn
