GBA is actually one of the more demanding emulators, so it’s likely just not holding 60 fps consistently. In this case, there’s unfortunately not much you can do. Newer hardware (iPhone 5+, I think) can handle it fine except for a few stragglers that still dip sub-60 occasionally, IIRC.
If anyone with an iPhone 4 knows differently, please chime in 
thank you for taking the time to reply and read normally ive never had a reply in any forum ive posted on and i hit 57-60 fprs like 2 out 10 times (fraction wise) but is there any like settings i can play with that will increase it?

Are you using the VBAM core or VBA-Next? VBA-Next will likely be substantially faster.
Is there any drawback on using VBA-Next vs VBA-M? I’m on recent PC build, so I don’t know if aside speed there are accuracy issues.
Yeah, there are a couple of accuracy tradeoffs on specific games. I don’t remember any details, though.
ok, no problem, I change to vba-m then, thanks for help.
