I found the MAME files I needed online to play Pacman but when I went to unzip them into the .Rockbox/Pacman folder I couldn't find the Pacman folder. I don't remember deleting it after installation but it is a possibilty. I tried to just make a Pacman subfolder in .Rockbox and unzip but it wouldn't load. I then tried installing a current build, still no luck. Any advice?
