HeroesTweaker is a creatively named program to edit certain data in the Tsonic_win.exe file, in the PC version of Sonic Heroes. It was written by igorseabra4 in Visual Basic .NET and is now a legacy tool, as using a mod loader is favored over editing the game's executable. The editors has later been ported into Heroes Power Plant making this program now obsolete.


As of Release 1, the program has the following features:

  • Mission Editor can edit the objectives of Extra Missions for all teams and all of Team Chaotix's missions.
  • Resolution Editor can edit the internal resolutions of the EXE. See the "Aspect Ratio" section in EXE Editing page for information on changing the internal aspect ratio from 4:3 to something different (like 16:9 or 21:9 widescreen) based on the internal resolution.
  • Spline Editor can view, import and export splines (as .OBJ files), which make up paths such as rails and loops. Not all levels are available since not all pointers have been found. Imported splines must be the same amount of points as the original.
  • Start/Ending Position Editor can edit starting positions for all 1P and 2P levels, as well as ending (victory animation) positions and bragging positions (the place where the teams make a comment to each other before the match) for 2P levels.

In the 2nd release which was released in July 28th, 2017, it has the following features:

  • Bobsled Editor has the same functioning with the spline editor, but it can do two splines with one left and one right.
  • Ranking Requirement Editor can alter the score requirements to gain a certain rank after completion of the level.
  • Unlock Requirement Editor can set the requirements for how many emblems, emeralds and story percentages needed to unlock a 2P mode or the final story.

The mission editors in this release are also separated and the resolution editor is absent.

A year after the development was abandoned on the 2nd revision, A third version was released on August 14th, 2018. Now the tool includes most, if not all, of the game's spline and bobsled entries.

Planned Features

As of October 2017, this tool is no longer updated. Sewer56lol's mod loader and his subsequent mod management utility were created as a replacement tool of Tweaker to allow manipulation of codes for Heroes with user written dynamic link libraries loaded in runtime.
