Just this weekend very one had a chance to get TN-V11 for Ape Escape for 3.36/3.50. While there are still many issue with TN-V11 and FW 3.350, the main problem is the you can not write to the game folder. So no homebrew & emulators unless you turn them into iso. Now ISO backups seem to work fine at the moment, as long as you put them in the TN-V save files.
Well, Qwikrazor87 has just released ARK for Ape Escape for 3.50, if you remember he just release world of pool exploit that worked fine with ARK. The next best thing about ARK is you can use the ONEMenu with some great features that come in hand, when installing your favorited homebrew, emulators, and iso backups.
