I just finished working on a project based on the GBA Link Arena by TristanS.
(Link Arena with all GBA Games)
This Romhack allows you to create Link Arena teams for all units from FE11 and FE12, alongside all DSFE Weapons and Classes and (mostly) custom palettes.
Every unit uses their 20/20 (or 30 or 20) averages as their stats, with every FE11 unit using their FE11 averages except Jake and Beck, who use their FE12 stats and classes instead.
The GBA Skills are still there, including Silencer on Julian and Rickard.
A list of all usable units can be found here (https://tiermaker.com/create/ds-arena-draft-16135306)
The Download also includes a Recruitment Map, since theres quite a few houses.
