how to patch:
NOTE that this patches "sfa2u" *NOT* "sfa2". sfa2u is the community standard and how the game is played on fightcade2.
remove 'sz2u.03a' from
patch using the included .bps file
place the newly updated 'sz2u.03a' file back into

If you’re playing it with MAME, you may be able to drop the ROM onto the exe, but otherwise you must launch modified ROMs from the command line for example, in windows, hit start, run, type “CMD” to bring up a command line. now go to where MAME is installed, and run the game using this command: MAME sfa2u

It should load up fine in fbneo and fightcade2, it’ll give an error about the crc32 being incorrect but just ignore it
