kayvenm has updated his port of Descent to the NDS again.

Release notes:

It seems most errors are occurring because of the lack of memory so I’ve add some code to check that and flush some cache memory when it occurs, so there maybe some more slow downs when cache is emptied/refilled but hopefully less crashes as a result. Also, this build is more optimized compiler-wise, so frame rate should be steadier.
