If Star Raiders were reprogrammed to take advantage of a redesigned game controller, you bet! The joystick ports for up/down/left/right are really *bi-directional* which allows them to be used to *send* data as well as receive it. Nintendo's joysticks are serial devices, for example, that send the button data one bit at a time under control of the CPU. There's no reason a Star Raiders controller couldn't be designed to do the same, and use the leftover bits to drive LED's. The hardware involved would be simple - all the parts could be bought at Radio Shack, probably. Modifying the software is the hard part, unless you already have the source code. - Jim -- To unsubscribe, send the word UNSUBSCRIBE in the body of a message to stella-request@xxxxxxxxxxx
