Ok, so I found out it was just mod conflict as to why my mod wasn't loading in the Mod Manager. Ignore my post from earlier.
What that means is the DC Convention mod is basically overriding my mod, but there's also something else because some parts of my modded stage doesn't go through right and some of the edits to Emerald Coast gets undone but not all of it. Sucks because playing SADX without the mods to make it less glitchy and awkward, well, sucks, if I want to test my levels but want the "authentic Dreamcast" experiences. Oh well, at least for now I can continue modding without being concerned it wasn't working at all in the Mod Manager.
