I thought that dvdisaster should work for DVDs based on the name, but it gives the error "this software does not support DVD-ROM type media" for DVD games and also for regular movie DVDs. Maybe the ebuild is limited to just CDs for some reason.
This is not saying it doesn't work with any DVD - just specifically that it doesn't work with DVD-ROM media. As someone else pointed out, these old game console DVDs might well be using a media type specific to that console - still not usable with dvdisaster. It (dvdisaster) would probably work with DVD-Data (if that's the right name for it) although that obviously won't help you any.
