Your save file (i.e. your unlocked stages in Stage Select, Match mode data and unlocked Weapons) is stored in the game directory as system.dat.
Unlockable weapons by number of Plays or Rank Edit
All weapons minus the Accelerator can be unlocked by reaching a number of plays, i. e. the number of times you start AND finish in ARCADE, STORY or MATCH mode. It doesn't matter whether you win or lose and get a rank E, Closing the game or returning to the main menu however doesn't count as a play.
Achieving a certain rank in a stage in either ARCADE or STORY mode can also unlock a weapon.
