  • C64 Hangup problem with reading debug register (D7FF): Fixed.
  • C64 Hangup when disabling SID socket: Fixed.
  • ARMSID config not working when UltiSid is in the same range: Fixed.
  • CIA2 I/O (UserPort) not working: Fixed.
  • Sprite collision in Antiriad: Fixed.

  • PIO register fault: Flimbo’s Quest now working! (Thanks to Tom Roger Skauen, for his debugging efforts!)

Known issues:

Corrupted disk access with some loaders, when bus bridge is not on “Quiet” mode, and badlines are disabled. We know this affects Geos MP3. Still under investigation.

    I have the U-64 and installed firmware V1.34 but I still have no clue if it is possible to have devices on the cartridge port (RAM/ROM/IO) also run at more than 1MHz.

    Anybody checked on this ?
