Cartridge dumping tool in Computers Posted August 23, 2018 · Report reply Ok, I've got my old laptop up and running thanks to a donor laptop I have, :-D anyway! I want to use bjl dump but I'm unsure if I'm using it right. I've got the jag on the ready orange screen. so now I want to use the autodetection setup so is this the command "BJL_DUMP.EXE try.rom 0 800000 0" I'm right and how can I tell if it's working? :? Thanks!
