First, what kind of mod are u using in ur ps2. Some chips dont requiring any rebuilding, but if ur using Swap Magic like me, all DVD-9 games must be rebuilt, as well with any games with a TOC over 4.35 gigs.
There is no point to rebuild a game if u dont have to, cause it can be a pain in the arse and a waste of time. Check out this link to c some common games that require rebuilding when using Swap Magic:)
Yes, all game apply to that TOC rule. And yes, u can play both NTSC and PAL games with SM, just change the setting when u boot SM. Did a search, found another link with TOC sizes. Will try to find more PAL TOCs in a bit:) If it exactly 4.35, u should b find do an exact copy with no rebuilding.
