Welcome! Back in the day the SEGA Megadrive / Genesis was expecting a composite video signal (Red, Yellow and White Cable) to add more colors and transparency to games.

On to the Next Section to start the Tutorial!

REQUIREMENTS
Sonic 3 A.I.R: https://sonic3air.org/
Reshade: https://reshade.me/
RSRetroArch Shaders: https://github.com/Matsilagi/RSRetroArch/

Alright assuming Sonic 3 A.I.R is installed already, its time to install Reshade from the link above.
NOTE: Put a copy of Reshade away for safe keeping in the event you need to uninstall it.

PART 1 - INSTALLING RESHADE

• Open Reshade and search for the exe for Sonic 3 AIR. It will be where ever you installed it.
  
• Once AIR is selected press Next.
  
• You need to select a graphics renderer for the game, Sonic 3 A.I.R uses Open GL.
  
• On the next page you will see a option to add presets, ignore this and hit next.
  
• Now will see the included presets, just pick next until all the defaults install are properly.
  
• Reshade is now properly installed. However we are not done as we need another shader.

PART 2 - INSTALLING THE RSRETROARCH SHADERS
Sonic A.I.R requires a shader that is not included by default.

• Go to the Github above, press "Code" and Select "Download As ZIP" to grab the stuff.
  
• With the ZIP downloaded right click it and extract it.
  
• Go Inside the newly extract folder until you find a "Shaders" and "Textures" folder.
  
• Copy both folders and go Where Sonic 3 A.I.R is installed.
  
• Inside where Sonic 3 A.I.R is installed Look for the reshade-shaders folder and enter it.
  
• Now paste the "Shaders" and "Textures" folders into this space.
  
• While the RSRetroArch shaders copy in say yes to overwriting any pre-existing shaders.

With that done we can finally start Sonic 3 A.I.R in the next section!

PART 3 - Configuring Sonic 3 A.I.R

• Turn on Sonic 3 A.I.R, Reshade will now begin to compile its shaders.
  
• Once compiling has finished hit the "Home" key on the keyboard to use Reshades settings.
  
• Search through your filters until you find one called Mdapt. Once found select it.
