Sonic Mania Modding

Recommended Posts

Well, in fact this isn't so surprising, looking that the game uses the same engine found in Sonic CD (2012), and we have a few programs to hack it, and looks like to fit perfectly in Sonic Mania, you can found one of these programs here.

The file Data.rsdk is the same used in Sonic CD, but obviously, the size are different, extracting it, you can find almost everything used in the game.

Yo, how do I extract it?

I downloaded retrun and every time I run:

retrun x Data.rsdk -2

I get an "Error creating directory during rextraction! Invalid argument"

Can't find anything online for assistance.

You are using -2 in the end of the command, use -3 instead, this is the Sonic Mania command. So, your command needs to look like this:

retrun x Data.rsdk -3

You can also use -d=xyz to extract to some other directory, where the xyz means the name of this directory, if this directory didn't exist, it will create automatically.

But, I didn't found many things,  many files are corrupted, there only five audio files that really works. Fortunately, I found other program that is compatibly with Sonic Mania files called X-Ripper, with this program I ripped the full OST of the game.

Extracting the Data.rsdk with another program, I find a few things, at least, interesting...

It seems that the game would have Scrap Brain as playable level:

I remember reading that on Sonic Retro, but no one had uploaded a image.

Also, sorry, I know that this is a Modding specific topic, but I need to post this in somewhere.

Or the Scrap Brain was considered to be the site of Titanic Monarch at first and then it was changed to be in Little Planet instead. As ending where it all began.

I don't have sure, as I read here, it seems that this Scrap Brain sprites was leftovers from the 2013 version for Android.

 

And well, it seems that there's nothing much to find in the game files, it seems my job is finished for now. Here, just some few additions that aren't in the website:

Unused Studiopolis Sprites

And well, I don't have much sure about this, but I think that can be interesting:

Hidden Palace from Sonic 2 (2013) on the game.

Also, the original name of Press Garden was Pulp Solstice.

Reimplemented the SEGA Saturn UI found in the game's files for XPadder + SEGA Saturn Adapter users. The files are over the Key icons for Mania's default KB control setup. Full mappings + installation is in the README.
