Releasing MGR Patcher – a simple and open source tool to patch Metal Gear Rising: Revengeance to allow any aspect ratio/resolution (at least on my machine)

I had a itch to play a game that I last enjoyed in 2015, but it turns out they did not future proof the output resolution and 1080p was the highest thing supported natively.

I looked online and there’s a binary circulating that purports to solve this problem.

Of course the classic “wait is this a virus?” compounded with the reports that alternate aspect ratios are also not supported had me ask “What a re-implementation would look like with a little RE magic?”

In between two Deadlock matches MGR Patcher came together, with Codex doing all the work.

It does a few things (in Rust of course):

  • Finds or lets you browse to METAL GEAR RISING REVENGEANCE.exe.
  • Creates a .backup copy before the first patch.
  • Replaces the game’s built-in 800x600 option with your selected resolution.
  • Verifies the patched bytes after writing.
  • Can restore the executable from the .backup file.
  • Can launch the game after patching.
  • After you approve the first Windows warning, removes its own Windows download marker so later launches are less likely to warn again.

The Github CI pipelines should build a windows release available, since I know you are all chomping at the bit to get back playing Revengeance.
