Sorry to hear your AR film did not work, where did you gets yours from? Bibin has used screen protecters, and I think I have suggested those, but I have ballz, so I pull my AR from old dead LCD panels. Most people do an anti-glare mod to get rid of AR film, I do it to GET it!
Might wanna try that, it is a lot thinner, might help with contrast.
It looks really clean, impressive work you have so early on. Keep up the good work! Add a prosound mod jack and a switchable overclock mod, and you have a nearly perfect GBC!
Can it charge the battery, too, or do you use an SP? I have a circuit that charges single li-ion cells, it works well.
