• Found the issue why the Emulator seems to be stuck when using small tickSteps in mainloop. I created a simple Benchmark and added missedIRQ and missedFIRQ counter to the CPU. The Emulator starts (although very slow) when using tickSteps of 393, but fails when smaller than 393:

BENCHMARK START, ROM: ./rom.freewpc/ft20_32.rom
