1. "able to trade something on pokemon" - did you mean wireless with another EmuMaster through GBA link emulation? 2. "when will the cheats work" - it's hard to implement full cheat support in GBA with CPU recompiler and I have major things to do know (PSX emulation) while it is not, it has rather lowest importance and priority right now, sorry 3. "is ingame saving possible" - I had no time to fix GBA ingame (flashcard) saving, but I will definitely check it before next release
