I've thrashed two Red versions and a Blue from glitch experimentation; My originals of both still sit in my game closet, though.
I'll tell you, there's only so much .4 a game can take before wigging out. Maybe I could dig out some of the old Emu videos or something and put them somewhere.
(I could go into a rambling explanation of why certain glitches do what they do but no one would want to hear it lawl)
And my Gold's come really close, doing what my Diamond sometimes does (The save file is corrupted loading last data saved etcetc but still loading where I saved) -- each time, though, it's because of the Machop thing in Vermilion.
Haha, it's fun getting results from being retarded on games. .-.
And I dunno what you guys are talking about - The only 'dangerous' MissingNO. is Yellow Version's.
(And Flying Kangaskhan ftw!)
