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.
