Metal Gear Solid 2: Substance Skateboarding Crash

[xantier]

The widescreen hack stretches the screen to 16:9 aspect ratio in MGS3, but as the skateboarding game uses a different engine(so basically a different game), the hack will affect a completely different part of the game that has nothing to do with the aspect ratio, in this case causing a crash.

I meant I can still play at 16:9 even though I disable widescreen hack, so what does it actually do?

The hack makes the viewing angle wider, so it's properly widescreen 16:9. If you disable the hack while playing, the hack won't get turned off. It will only go back to the original 4:3 after you reset the game or load a savestate. And if you had the patch enabled when making a savestate, loading that savestate will activate the patch even if you have "enable widescreen patches" disabled.
