Open Smash Attacks
Open Smash Attacks, more commonly known as Open SA, is a Brawl moveset editor with the goal of serving as a side tool to BrawlBox by editing and representing files that BrawlBox cannot or can but poorly. Open SA is significantly more advanced than its predecessor, Project Smash Attacks; It can view the actions and hitboxes of most props and projectiles, open character files that PSA has trouble with, and work with files that house general actions for all playable characters. Open SA's major downside is the complexity involved in editing files and there are some facets that cannot be accessed or edited such as Pikmin hitboxes.
