- Glitch City is just a garbled up map that causes the game to freeze if you make it to the loading lines.
- The walkthru walls glitch is just a helpful utility and can't really be used to get into any awesome "secret" or glitch areas, unless you count hitting a loading line and making the game crash "glitching".
- Missingno does very little except garble your Hall of Fame data, levels erratically, messed with sprites and screws up your trainer card. It doesn't erase your file, and only 'M messes with your PC.
- The "error 0" extension of the "mew glitch" just gradually slows you down until it causes the game to crash and spit out random sounds.
I dunno, I guess these glitches all seemed like magical sources of endless entertainment to me at some point, but now, the only things that seem even slightly fun to toy around with are the high-hex "glitch Pokemon" like the ZZaZZ glitch, which I've not yet been able to effectively trigger. I dunno, maybe I'm just not looking hard enough? These are by far the most glitchy games I've ever played in my life, and I wouldn't be surprised if there's still more that can happen if someone happens to stumble upon something.
I play Black Ops because I'd rather play a terrible game with my friends than play a good game alone. Black FC: 0991-1063-0052
