Fix for "Steam user must be logged in to play this game"

[Tenjoin]

UPDATE: An update was pushed just today for Sonic Mania! The guide below may not work anymore. Launch the game once online and it should work.

Either use the IPS patch, the SpecialK fix or follow the guide

IPS patch[drive.google.com] by shicky256

SpecialK fix[gitlab.com] by Kaldaien

----------------

GUIDE:

1. Make a copy of SonicMania.exe
2. Open SonicMania.exe in a hex editor
3. Go to 1CAABE
4. Overwrite the byte with: EB

Before change: 75 30
After change: EB 30

----------------

A more foolproof guide by SenMithrarin85:

1) download hxd and install it
2) make a copy of the game's exe
3) open hxd and then click file>open
4) open the sonicmania.exe
5) press ctrl+g in the box that appears, type 1CAABE and then press enter
6) the program will navigate to 2 values before a 30
7) Do not move the cursor. Type EB
8) it should read EB 30
9) press ctrl+s and close the program
10) replace the game's exe witht he edited one
11) play offline!

----------------

A simple short jnz to jmp change, basically. Done in 5 minutes pretty much.

Please keep in mind this is NOT bypassing any security mesaures per se as users with these binaries will not be able to run unless SteamAPI sees that the user owns the game.

You should tell Sega about this.

I'm pretty sure it was a simple unintentional oversight in SteamAPI settings for the DRM. This just forces the login check not to quit the game (as a quick hack, mind you, this will NOT crack the game in any way).

Hey there, sorry, Steam disconnected for me for a second.

Basically, you hit Ctrl+G, write 1CAABE in the box, then on the hex side you just write EB 30 and then you save the file (Ctrl+S)
