Simple modding utility for Streets of Rage 4

This small utility shows a file navigator and allows you to browse the game's textures, copy them to the clipboard, and export them as PNG.

Eventually, it will also allow you to replace textures, but at the moment it's unclear if the game would load additional texture files or the replacements need to be written inside the existing big files, which would be pretty cumbersome and slow.

This program uses the .Net Core 5 preview. Get it from

https://dotnet.microsoft.com/download/dotnet/5.0

and then

dotnet run

• Drop the SOR4 installation folder (which will contain just a 'data' and a 'x64' subfolder) into the window.
• You can double click an image and export/copy it from the image's context menu, drag them to a folder, etc.
• In order to export textures in bulk, right click a folder in the left tree and choose 'Save as...' (warning: slow!)

The game seems to be very data-driven.

The file named 'bigfile' contains a serialization of custom .Net objects including data for all the characters, moves, levels and a lot of other stuff. If this file is correctly reverse-engineered, there is a chance modders would eventually be able to add new character or moves to the game, instead of just making texture swaps.
