Hi Franz,

Thanks for the update. After unzipping from scratch, 1X runs fine using MessChess.exe and MessExtra.exe; on another hand starting from CB-Emu.exe I get a number of messages looping:

Driver xxx (file winboard.cpp): 1 errors, 0 warnings
Errors: Driver is missing MACHINE_NO_SOUND flag

where xxx loops across a number of devices names (boris, borisa, ...)

then the emulation prompts "No screens attached to the system"
any idea? Other devices I tested run fine.
Thanks and regards,
Eric
