Ahh, good old EGM.  That buyer's guide was one of their best issues.  Super Famicom Preview, a couple of 10s for Turbo games in one issue...  oh, and massively incorrect tech specs.
But I wouldn't take EGM to task about the CPUs for the TG and NES: they are essentially 6502s.  The TG's has several great instructions added in, and the NES' has a few taken away, but they are very code-compatible with your average 6502 program.
