The MYTH crack works. It's a generic flash player replacement. They just watermarked their name into some empty space. It's safe.
Republic Commando = Securom 5.03. I'm surprised if there's not a nocd available somewhere ... I played it a long time ago but can't remember how.
Battlefront II = SecuROM 7.12. Danger flags. It's a popular game so there should be something out there ... If you can find the DVD-5 1.1 re-release, it should be protect-free.
(wish I had more time to look into at SW:RC. SW:BF2 would be a killer being the S7 family. I remember playing a Disney Princess game that was S7-protected also.
