Hello, im new to trying out this game for speedrunning and I wanted to make sure that all my files and everything is up to code and in order. I have the emulator FCEUX 2.2.3 and have a Dig Dug ROM from romhustler, but it turned out to come with a bunch of different Dig Dug ROMs... so I want to see if there is one definitive one that runners here use? Or if I have to have a specific version? The one I have been trying glitches out at Round 4, thanks for all the help!

Yeah, Romhustler gives you a whole bundle. I think the one that's named "Dig Dug (J).nes" should be fine, just specify region as NTSC Japan when you submit your runs. I don't really know the difference, but I think some confirmation from the moderators would be in order.
