I don't know if any of you guys can help but I am trying to run the Naomi version of monkey ball on my Pi 4b 8gb on retropie. I have the naomi.zip and naomi_boot.bin bios files on the pi and I have the correct monkeyba.zip file with the 317-0307-com.pic file inside, and I also have the gds-0008.chd file. I also tried all of the region's in retroarch and nothing has worked. Any help is appreciated.
