There's no such comprehensive list. Maybe someone (possibly me) should try to get one together on riocar.org. There are some older games, apps, etc. which don't integrate with the Hijack interface, and therefore aren't as useful. But several apps have been released that actually integrate with Hijack. I've released an alarm clock, a trivia game, and an image panner, all available on my empeg page. John Heathco wrote a text file viewer which is available on his page. Bitt Faulk wrote a preinit program which doesn't actually bind to the Hijack interface, but it's important for starting programs that do bind to Hijack. There's a couple other things out there that I'm forgetting about, and I have a couple other things under development as well.

Since I have admin access to riocar.org, I should probably try to keep an up-to-date list of apps. I'll try to do this in the next couple of days, and when it's done, I'll let y'all know.
