Wow, fine !

Did you rely on 65Host for 6502 emulation, or you wrote your own 6502
emulation code instead ?
Do you recall how many (arm) instructions did it take (more or less,
or on average) to emulate a 6502 opcode ?

Things like
if(Z) then R1=R2+(R3*4) -->> EQADDS R1,R2,R3,LSL #2
Conditional-execution... lovely ARM things !
