So not a lot of people realize this but unlike Secret of Mana, Seiken Densetsu 3 only supports 2 player. Fixing this and playing the rather popular 3 player hack on the PC is rather easy but on the Retron 5 it's not so much as you can't stack multiple patches on it. Here is the translation patch for Seiken Densetsu 3 with support for 3 players:

There is also a patch to convert the title screen from "Seiken Densetsu 3" to the slightly more localized "Secret of Mana 2", The follow patch has that applied as well as the 3 player hack:

I will mention apparantly there is a bug in the game when having all 3 players enabled, I have not been able to get confirmation on what this bug is and where it occurs but supposedly it's minor. That being said
if you'd prefer just the plain old 2 player version translations here they are:

Seiken Densetsu 3 (Secret of Mana 2 title screen):

Keep in mind, I did not make the original patches the above were sourced from. I've just neatly stacked and fixed them to work on the Retron 5. Credit goes to Neill Corlett for the translation itself, Parlance for the 3 Player hack, and Jezze (aep-emu.de) for the Secret of Mana 2 title screen change.

R9Delta you are the man!
