Seiken Densetsu 3 / Trials of Mana - 3-player Hack (No Header)

v1.0, by hmsong

Many people are already aware that Seiken Densetsu 3 already has a 3-player hack (, but that patch is specifically for Headered ROM, which is incompatible with most of the other hacks in the internet. After getting multiple requests, hmsong decided to make a No Headered version of that particular hack, so that the public will have access to this without having to go through the trouble of… well, lots of things.

Warning: There is a minor plot-bug that comes with this hack though (the Headered version had this problem too), specifically in the Ghost Ship section after one of the players is forced to leave the party (due to the plot reason), assuming all 3 characters were controlled by three players. If one of the players dies and is revived by the other, then the revived character will no longer be in control of anyone. The creator didn’t actually tested this, but it’s been confirmed by multiple people in the hack community, so the source of this info is reliable. Perhaps some of the details are wrong though, so feel free to just google it for more detail.

Applying Notes:

  • This is specifically for No Header ROM. If you only have a Headered ROM, then you can use TUSH ( to remove the header.
  • Compatible with the English NCorlett-translation patch. But again, you need a No Header ROM. If you are using the translation patch from, then you need to apply the translation to a Headered ROM first, then use TUSH to remove the header. And then you can apply these patches.
  • Compatible with the new Trials of Mana ROM, released in 2019. But again, you need a No Header ROM.

There are other hacks for Seiken Densetsu 3 that you should check out:

Sin of Mana

  • This changes the contents of the game in many ways, such as equipment bonus, level-up change, class balance, difficulty, boss behaviors, running in battles, MP regeneration, dungeon format, and tons of bug fixes. It’s a completely new game though, since so much has changed, and the game progress is slightly different.
  • There is also a forum (google “Sin of Mana forum”), where you can ask the creator (praetarius5018) numerous questions. He is very helpful, and even helps you to create your own hack. He certainly did for me.
  • Sin of Mana is NOT compatible with the new Trials of Mana.
  • Sin of Mana is NOT compatible with hmsong’s patches.

Please leave comments or reviews. This would give the creator ideas on what is good or not, and depending on the situation, even revise the patches. You can also send the author an email (address in the attached document).

Long overdue.

Reviewed By: Nintenja on 19 Jan 2023

This will make the barrier of entry into having a 3 player version of Trials of Mana much easier. This hack also makes it easier to mod the game further as most hacks are for an unheadered trials of mana rom. Great work hmsong and much appreciated.
