That means that the problem with GnuBoy is something else than forgetting to free normal memory allocations I guess.Thanks for your tests!
I just tried GooPlayer on my brand new Dingoo (pawed, I think) and it freezes when I launch it.Actually, every homebrew app freezes the same way.The other native games/emulators work well. The firmware if 1.2.Anyboby's got the same problem ?
