I think his point was, that it's too hard not to end up copy/pasting half of MAME's CPS source code when using it as reference. I'd much rather base an emulator on technical documentation instead (eg. basing a Z80 emulator on the official documentation by Zilog themselves instead of Juergen's Z80 core in MAME).
