Games freezing at random. Help please.

32bit programs are limited to the amount of ram they can use usually it's around 2 gigabytes , java and jpcsp can fill this ram up pretty quickly and when it runs out it will usually crash, disabling options like vertex cache can help lessen the memory constraints, also increasing the xmx size in the bat file (or sometimes lowering can also help).

64bit doesn't have much memory restrictions so jpcsp will almost never run out of memory if the options are configured correctly, unfortunately not much can be done with 32bit since its a limitation of the OS.
