Yeah I expect a non-compliant adaptor. Though I doubt the USB HID support is rock solid investigating these individually takes too long. Does it have a built in hub? The USB hub support seems a bit iffy to me. foft

FO 09:59 AM EclaireXL Bug #20: Bugs in DAS OMEN Demo

We could add another 6502 for the firmware to replace the zpu. I'd like that but don't have time to spend on that.
Quite a job though to rewrite the firmware.
It contains sd card access, fat filesystem, file browsing and a usb stack. foft

FO 08:05 AM EclaireXL Bug #20: Bugs in DAS OMEN Demo

We can try it. Do you know c? There is atari_drive_emulator.c in the firmware which has a copy of the xex loader. Its an sdrive port and I didn't ever look into the xex side much. foft

FO 10:05 PM EclaireXL Feature #2: PBI support

Interesting the acid test now fails with this core, which explains the blips I got when running real cartridges before. So probably some antic timings are wrong when the active cycle is in the 2nd colour clock of the cycle. foft
