i read that you have to force ntsc and stuff in neogamma, but how do you fix 002 error?

 

If you get 002 error in the latest NeoGamma, then you used a bad patch on your disc, try again with an unpatched one.

002 fixing always activated in NeoGamma, but fails if the disc was patched to use another IOS(in the disc channel or when doing an IOS Reload!).
