Has anyone ever done any button mods before?, im sure it's not just me when it comes to not liking the original buttons or dpad, any ideas or sites where I can get ones that are more firm, or just little ways you guys did it.? I had an old gameboy advance and tryed to use that dpad but it's just too...

I getbthis on boot up and when I try to quick save it says "task failed : save state " what do I do im New to this.
