Figured out how to burn cartridges for the PCJr. The binary file for Cartridge basic floating around has some header message stuck to the start of the .bin. Once I figured that out I stumbled my way through a hex-editor and got it to work. Will post the fixed file on my SDF website
@junkman have dumps of all the ROM cartridges been made yet? What about making a flash cart based on the cart boards that are out there?
