Could this be used on an rgb modded GT do you think? That would be really cool
There does seem to be a bit of skullduggery surrounding McWills game gear lcd though:

This Driver Board uses RGBS-Input and converts it to LED-Displays. And it is always sold out.
You can use it for that and they will only sell to people in Japan who speak Japanese.
Wait what
