I am just wondering if there would be any way to run these Games. Basically there are Boss Hacks, Color Hacks, you name it. But the BHs are better. They work in the PSP Emulators CPS1PSP, CPS2PSP and MVSPSP. Other than that, there is a WinKawaks Hack that allows for them to run. http://neo-nebuwaks.blogspot.com/ Just have not seen much of these in quite a while though.
Mainline MAME refuses to support rom hacks of any kind except for bootlegs. They can be added manually by editing the internal databases before it’s being compiled, but the libretro port tries to avoid such intrusive changes in order to stay upstream friendly. FBA does support them, but it tends to be somewhat behind so newer hacks might not be recognized yet. Like MAME adding them requires editing the internal database, so it’s better to ask FBAdev about supporting them.
So basically if the hack doesn’t work in FBA you’ll need to contact the devs about it and then wait for them to release a new update.
Would HBMAME be possible to create for this purpose? Or as I read, make the CPS1PSP, CPS2PSP and MVSPSP Cores available for all Releases like 3DS, Android, Vita, and others. I know there are MANY Mods out there that allow for the Homebrew/Hacked Roms.
There is theoretically a way to get to work without hacking MAME/MESS specifically, but it does involve a bit of hacking and some knowledge of the MAME/MESS hash format., and only works for the Neo-Geo.
I’ve gotten a few hacks to work that way with mainline stand-alone MAME. You need to get the hack’s crc and sha1 (for each file inside the rom) and then it’s a matter of working out where what goes and testing it on MAME to see if it work. I ended up with a 75% success rate when I tried a year or four ago.
