The main issue with the Dream Blaster (light gun for the Dreamcast) is that most people report having issues with them where it doesnt want to register a hit even though youre pointing right at it. and so its not known if the gun itself is bad or there is an issue with the monitor. some people say their gun works just fine. so youd have to find someone with a gun that works just fine. unfortunately I fall into the former category of having issues with mine. id be willing to lend you whatever you would need, but again, dont know how well its all working. I also have a PS1 GunCon, a SuperScope, NES Zapper. I think the hardware tests on your 240p test suite are the most valuable part of it so itd be great to see that expanded with all of the different accessories out there.
