The ROM info is from FBA Plus. Can you be more specific about how it mistaken and the source of your information? In any case I doubt I will remove the set since it definitely exists even if a correct dump is not yet available. P roms are the same for mvs and pcb versions, v is 16 mb and it´s the same mvs data but concatenated, C roms protections are very similar to svc and m1 is 256kb. Only the bios crc is unknown ATM. The information came from a source much more reliable than ferchogtx. The information is private but i´m sure it will be released very soon (maybe it will be in some very well known neogeo reference dats....) btw here is the information from the clrmame.dat rom ( name 268-bios.bin size 524288 crc 00000000 ) rom ( name 268-c1.bin size 16777216 crc 00000000 ) rom ( name 268-c2.bin size 16777216 crc 00000000 ) rom ( name 268-c3.bin size 16777216 crc 00000000 ) rom ( name 268-c4.bin size 16777216 crc 00000000 ) rom ( name 268-p1r.bin size 4194304 crc fc4e18b6 ) rom ( name 268-p2r.bin size 4194304 crc 216b559a ) rom ( name 268-m1.bin size 524288 crc 4a5a6e0e ) rom ( name 268-m1_decrypted.bin size 524288 crc 2f621a2b ) rom ( name 268-v1.bin size 16777216 crc 8458afe5 ) Mistakes found: Missing Crcs: Bios Still needs confirmation (Unknown) c1,c2,c3,c4 Known but private Incorrect Crcs: p1,p2 Anyone knows where this roms are or where did this crc came from? The program roms for pcb are the same that were used in MVS. m1 Real pcb m1 is 256kb crc is known m1d Even that m1d is incorrect, the F800-FFFF data region is missing, and it should be 256 kb. crc for a 100% decrypted rom is not known but if you split that one in 2 parts it should be very similar to the real. Correct Crcs: V1 It´s the only rom that can be confirmed as real in that set. Finally it has no sense to have a not working set that it´s incomplete, and where most of the files and protections are not public. The worst is that it makes even harder to identify real roms One tip: you know people that can confirm what i said, and have even more information than me *EDIT* Now crc are known for new fba plus u7 game ( name ms5pcb description "Metal Slug 5 (JAMMA PCB)" year 2003 manufacturer "SNK Playmore" rom ( name 268-p1r.bin size 4194304 crc d0466792 ) rom ( name 268-p2r.bin size 4194304 crc fbf6b61e ) rom ( name 268-c1.bin size 16777216 crc 802042e8 ) rom ( name 268-c2.bin size 16777216 crc 3b89fb9f ) rom ( name 268-c3.bin size 16777216 crc 0f3f59e3 ) rom ( name 268-c4.bin size 16777216 crc 3ad8435a ) rom ( name 268-v1.bin size 16777216 crc 8458afe5 ) rom ( name 268-m1_decrypted.bin size 524288 crc 2f621a2b ) rom ( name 268-m1.bin size 524288 crc 4a5a6e0e ) rom ( name 268-bios.bin size 524288 crc 00000000 ) ) The only incorrect roms here are m1/m1_decrypted AFAIK. Bios is still missing too.
