Yes, I have tried all possible hardware emulations on Altirra.
When setup correctly, they all work perfectly.
To setup, that is sometimes a bit tricky where to tick and where to untick.
Also be carefull wat ROM images you use. Some MyBIOS roms require a matching MyIDE-][.bin
As for 1mb flash + Myide, you need to select the hardware and rom image seperately, where as MyIDE-][ has a firmware entry.
What time of HD-image you use, does not matter, all what altirra accepts works fine.
Be carefull what accellerations you tick in altirra, not all are compatible with MyIDE-I/O
Now on the real hardware side: On a A800, you need to modify the cartridge signals.
It has a different signal on the LEFT-slot O2-pin, see my previous topic how to mod and where to find images of how to.
Simple fix, cut one trace and jump it over from the right-slot (that has O2 connected on the same pin....).
