If you make something capable of running 6502 programmes using TTL then it most certainly is not a 6502.
If you take the 6502 decap and use the die shots to make masks & run a chip fab in your kitchen then you can claim to have made a 6502. Anything else and it's just pretending to be a 6502, AKA emulating.
A hardware emulation is still an emulation.
Which "6502" is the real one that you need to decap to make your own one? The first publicly available one from 1975 with all the bugs, the one from 76 which fixed the ROR bug, the later CMOS version that fixed the 'JMP ($xxFF)' bug amongst other and added additional instructions and addressing modes or one of the dozens if not hundreds of variants that have been designed and manufactured by several companies over the past 40 odd years. By your definition everything but the 1975 die ones are just pretending to be a 6502 AKA emulating one I suppose? :rofl:
