Essential improvements[edit]

Sega PC Reloaded[edit]

Simple and easy-to-use launcher with many options and tweaks.

Korama's Sega PC Reloaded is an fan-made installer, launcher, and patcher for some of Sega's older PC games. It fixes the need for Sonic CD to launch in 256 Color mode (not natively possible on later Windows OSs), creates the necessary .ini file to turn off the game's disc check necessity, and enables Vsync to maintain the game's original gameplay speed, among other features.

Installing the game with Sega PC Reloaded[citation needed]
  1. Insert the Sonic CD disc into your CD drive or copy the GAME folder from the disc into your computer.
  2. Download Sega PC Reloaded from the link above, run the launcher, select the Install Game option, and then select Sonic CD.
  3. Select the Select source option from the menu to install from the disc or the folder containing the game's files, then you will be asked to find the drive letter where the disc is located (e.g. D:\) or the game folder, afterwards the launcher will then ask you to create a new folder to install the game with the patches. Alternatively, you can install the patches into <path-to-game> by selecting the Already installed option to patch the game.
  4. If the Sega PC Reloaded launcher has detected the game, you can adjust the settings as you see fit, then click Launch! to play the game. You should see "Korama's patches active!" appearing on screen when launching the game.
