I'm currently migrating the gp2x project website and merging it with the gp32 website. Sorry for the inconvenience.
In the meanwhile you can get Spout for the GP2X from the archive.
The Spout port for the gp32 should be somewhere in the archive too. Bastardshell might as well be there, but there are way better shells out by now anyway.
Well.. and Super Mario War for the GP32... my port never really got far, but someone else did one. Also in the archive. Yay hooray!
