i burned two games, but for some reason, now i am not getting any color. i have tried two different games, and the same thing happens
It's because your games don't match the region of your TV's signal standard. As in, if you play a PAL game (Europe) on an NTSC television (US, Japan, etc.) then it won't display properly. Black and white being one of the possible results. There's a couple workarounds, but your options are limited depending on what methods you're using to boot the back-up, what chip, etc. Some soft mods (Ninjamod and GCoS) as well as the Qoob Pro have video force settings that'll allow you to play those games on whatever standard your television falls under. If you aren't using one of those, then I can't really help you since other workarounds will cost some money.
