How do you save space on NeoGeo roms?

i know for the cps2 roms you can delete all the files .13 and up once the cache is made, and i remember someone saying that this method was the same as "with the neogeo roms"....

what files can you delete with those? thanks for the help in advance =)

You can read the files needed to delete while you make cache of it.. You can take a note but it's usually the _Cx files.. (eg aodk_C1, _C2, _C3 etc).. Worked for me hope you too..

thanks :)
