Anyone Know How to Hack the steam port of Sonic CD?

[alexmega30]

Hello, I wanna do some sprite mods and music mods for Sonic CD (2011), I tried to find some tools and tutorials, but I found neither of those, any know how to?

Look into a tool called Retrun. It can unpack the .rsdk format that the Data is stored in, and you can modify the sprites and music from there.

I'm not familiar with the tool, but judging by this text, it should be able to repack the rsdk file:

Retrun-Sonic is a packer/unpacker for games made with The Taxman's Retro-Engine SDK (RSDK), which means, yes, that you can now
unpack the datafile of the new Sonic CD remake, modify the contents and then make a new datafile with the new contents, thereby modifying the game data.

Whenever i open Retrun it quickly exits.

Retrun is a program you use in CMD.
For example, if you're trying to extract the Sonic CD RSDK file, you would type:

retrun -x data.rsdk -d=FolderNameToExtractTo -2

into Command Prompt.

So in my case this command prompt is not working. Also this tutorial is also not working anymore. So I downloaded rsdk extractor. I know this video tutorial is old,right? There's also another not outdated video tutorial.

RetroED.exe stopped responding so I had to close the program. It crashed,but why? Also so sorry that it's written in polish language that you don't understand. At least I translated some text for you.

You're probably missing a runtime framework. Make sure you have the C++ runtime installed. You can get it from Microsoft's site.

I want to know one thing what happened with Sonic Mania Mod Studio why download links are no longer available and also old modding tutorials are outdated did creators of Sonic Mania changed a file structures in later updates aka Sonic Mania Plus or what? I really liked that old modding methods and I'll miss them.

As you see here I also changed some sprites.
