Someone on SSRG posted a request for help with getting a level they had converted into Sonic & Knuckles Collection, but there was no easy way to do it, so I sought to rectify that. The S&KC Mod Loader has all the same basic features as the SADX/SA2 Mod Loaders, it can load DLL files containing custom code, it can load data from an INI file, and it has cheat code support. The one thing it doesn't have is file replacement, due to all the game's data other than music and sfx being in the EXE. Download To create a mod, create a folder within the "mods" folder of your S&KC install, and add a file named "mod.ini" within that folder containing the following lines: Code (Text): Name=Mod Name Description=Mod Description Author=Your Name Additionally you can add a DLLFile line pointing to a DLL file to load, and an EXEData line pointing to an INI file listing data to be replaced in the EXE. The S&KC disassembly has been updated to include more split data files, all the levels in SonLVL's INI, and an example INI file for the mod loader's EXEData setting. Note that I have only done minimal testing with unedited AIZ1 files.
