Has anyone figured out how to alter the mame settings on this box? I found the roms but not the emulator files. The PB4 instructions out there don't seem to apply.
The key with PB is to mount the SD card on a Linux box (or VM) since it's a Linux file system (ext3?). At that point, you can edit the flat files as you wish. The KoA has its config files either encrypted or hidden in some other way.
Here is a link to a site that has some PB4 hacking information. I am also looking into changing the Neo Geo bios, so if I figure anything out or find any other resources, I will post them up.
I bought a PB4x from the guy that maintains the site specifically because he leaves his open for people to mess with. It is possible to boot between Pandox Box 4, King of Air, and Xmame on the board he sells.
Also, here is a thread I found with some useful information about Pandora Box hacking.
