I was searching google and I found a java vm for gizmondo. It is called ewe and is an open source java vm:
It doesn't have all the java classfiles but these are given with the java sdk so it could easily be expanded.
But sadly I am not a c++ programmer I only know java. So someone would need to port this
But if we could get this to work anyone could make games for psp using Game maker and convert it with my wip gm to java converter called G-java
so what do you think?
