Hello everybody, sorry if I start immediately with a problem, I hope to be in the right section. On Ubuntu 20.04, I installed via repository ppa.launchpad.net/c.falco/mame/ubuntu, I dusted off old found roms. For a game, it tells me that I am missing this file: kd29b.1a I tried to search around the internet, but couldn't find anything ... Can anyone advise me? Thank you!
