Known Problems

Please understand that due to the nature of FPGA based hardware, many problems might get fixed with a firmware update at some point. For this reason we list only "persistant" problems here, like actual hardware bugs or long standing firmware bugs. For details please refer to the icomp wiki.

Software supporting special features

Listing software that requires one or another special feature only available on "modern" hardware and/or emulators, such as the Chameleon, 1541_Ultimate or VICE.
