Ouendan/EBA/Ouendan 2 Touch Screen issues

I actually have a couple things.1) Ouendan-The emu seems to run ridiculously slow, but just for this game. I've got No$gba set to Unlimited-MHZ Disaster, 512k Ram, Digital Mono, Low (10kHZ), And Fast/Fast. Should I be changing something here?
-The touch screen is really hard to see. The touch buttons are lit in such a way that they're too bright and impossible to see against anything except the black background. Emu incompatability, or am I doing something wrong? Also, the colors go weird occasionally (I.E. too green, etc.)2) EBA
-Same touch screen issue as Ouendan, same settings.3) Ouendan 2
-Same touch screen issue, but at least the game has girl cheerleaders.Help, yes?

This is probably a case of NDS emulation just not being good enough yet, not every game can be emulated.
