Homebrew Question RetroArch Help with Sharp X68000

[Dvdxploitr]

I have the BIOS files but when I try to load up the core and check Core Information, it says "missing". I have it in /retroarch/system/keropi . I have both the iplrom.dat and cgrom.dat file. I am using the 1.7.5 version of RetroArch and the NSP version
