In my preference I like my Neo Geo MVS games separate from MAME/FBNeo. I plan on right now creating my own dat, playlist for it and maybe it’s own icon for it which I can whip up via InkScape
One of the complaints I have seen on Arcade is that it is cumbersome to do it by having it match up with CRC hash algorithms. I think a naming convention should work.
Side note, for hash algorithms for checking the integrity of a file the ones used are depreciated from a CISP standard. I have seen in the dats the use of CRC, MD5, and SHA-1. Even SHA-256 is depreciated,I could use SHA-512 but that may be unnecessary for this sort of thing. I am unsure if Retroarch and Lakka support SHA-256 or SHA-512.
I could just do both a file name matching and a hash algorithm match since there are no where near as many mvs roms as MAME/FBNeo sets.
I do need to find out which one to use for Roms for the hash matching. I have a image below, they both work but which one is the correct or preferred format to use in a dat. The one on the left does not match up the dat from regular scanning and the one the right does.
A draft of what I have right now for my dat
I could use some input here
