Hello, I've had some issues with my really old tablet an Archos 8o G9, it doesn't run anything at all and it's slowly dying as all tech should at this time... But ! i want to turn this old useless tablet into a full-fledged ereader, so here's my question : is there any costum rom that is simplifed at the point of running one app only for maximum performance ?
