Nice result! It may give a -certain- answer on the Z80 VS CBM speeds.
Although it surprises me a little, but the problem of the bad lines and RAM/ROM switching seems to closed out in this one (this seems really generates a major slowdown on the Plus/4 and C128. I do not know what could be a real solution for that in a 8bit machine. Even SAM Coupe ( a very very advanced 8bit Z80 machine introduced in 1989 (!) suffered major slowdown due to shared memory with GPU and bad lines (wait states) https://en.wikipedia.org/wiki/SAM_Coupé#ZX_Spectrum_compatibility )
Question, if they could do the same improvementson the CPC too to be fair?
