SOR4 Swapper

A modding tool for the Streets of Rage 4 game

This app allows you to mod Streets of Rage 4 by swapping specific characters, items, breakables, and/or levels! This app only works for the Steam version of the game as far as I know and is known to work only on the v8 patch of the game (v08-s r18163) released in March 21, 2023.

Project Details

• Language: C#
• Supported Operating Systems: Windows 10 and newer
• Download: https://sourceforge.net/p/sor4-character-swapper/
• Source: https://github.com/honganqi/SOR4CharacterSwapper

Usage

• To get started, load your game’s bigfile into the app. It is usually in C:\Program Files (x86)\Steam\steamapps\common\Streets of Rage 4\data.
• You can swap or randomize characters, items (pickups), breakables, and levels by going to their respective tabs.
• Once you’re done adding your swaps, randomizing or after loading a swap file, click on Apply changes.
• You may use Save settings if you want to back up or share a swap list you made. You can use Load settings button to load the swaps into the app.
• After applying swaps for the first time, a backup named bigfile_rep7_backup will be created automatically in the same folder. This will be needed by the app to allow you to restore your bigfile.
• If you have a modified bigfile containing swaps, you can extract those swaps and save them onto a swap file by clicking on Extract swap list then showing the list and clicking on Save swap list.

Randomizer

• You may randomize your swaps for surprise games. e.g. Clicking on Enemies only in the Characters tab will randomize enemies only and clicking on Everybody will randomize everybody including playable characters. Click on Apply changes if you’re settled with the list or Clear list and randomize again if you want.
• The IGNORE checkboxes are there if you want the randomizer to ignore them during randomization. You may also use the ISOLATE checkboxes if you don’t want those categories getting randomized with the regular enemies. You may choose to disable these settings. They are safe and won’t damage your game but I cannot guarantee the same for your sanity.
• Characters and items in the swap list will be ignored by the randomizer. e.g. If you manually swapped Galsia into Goro, Galsia will be ignored in the randomization.
• You do not have to close the app when you run the game and you can execute swaps while the game is running, but you have to restart the game for the changes to take effect.
• If you want to randomize again without closing the app, click on the Clear list button before doing so to remove all the characters in the list.
