Why don't some of my MAME 0.78 ROMS load (I know I know, I'm sorry for asking!)

I know this is a classic question when it comes to RetroPie, but I'm still at a bit of a loss as to what to do. I've obtained what I believe to be a decent MAME 0.78 romset, yet only the older games seem to work. Stuff like KOF/Golden Axe/Street Fighter etc. don't seem to want to boot even across different cores. Others will load but then display a message about bad checksums etc.

Do I need to find a better romset? I've avoided Arcade up until now because of the horror stories I've read!

It's expected your 0.78 romset isn't going to work across different Mame cores. You should only be using mame2003 or mame2003+ with your 0.78 romset. If you get a bad checksum error with mame2003 then I suspect your roms are not from the 0.78 romset.

So in theory should everything from the 0.78 romset run with mame2003? Because it sure doesn't right now

@sad_muso some ROMs still won't work correctly with mame2003. Let's face it, it's 17 years out of date. Mame has come a long way since then. For KOF I would recommend using finalburn neo. However, iirc, goldenaxe should work fine and street fighter should definitely work with Mame 2003.

as per https://retropie.org.uk/forum/topic/3/read-this-first, please supply a verbose log.

@sad_muso if mame2003 (aka mame 0.78) is complaining about a set supposedly made for mame2003, then your set is crap.
clrmamepro is your friend.
