To publish a demo, you first need a program that can create .RAR or .ZIP files. If you don't have one, get the trial version of WinRAR. If you want to add a demo-like feel, limit the roster to a few characters, but not so that there are 4 like in the SSB4 demo! Use characters you want in the demo, or popular ones. You should do the same for the stages, but put in just enough so that players have a variety to pick from. I recommend that you make arcade mode end halfway, or don't include it at all. If you do leave in arcade mode, make a storyboard ending (You could use KFM's as a base) that advertises the full game and what the player can expect in it. Once you've done all this, if you have WinRAR (Trial or full), right click the folder for the demo and click "Add to (Folder name).RAR" and wait for it to finish compressing the files into a .RAR file. Upload this to Mediafire, 4shared, etc. and give the download link to the public whenever you're ready to release the demo. If you're using Megazipper, right click the folder of the demo, but click "Add to...". Then, 'Windows explorer' should open up and you can name the output .ZIP file for when it is done. Once that is done, upload this to Mediafire, 4shared, etc. and give the download link to the public whenever you're ready to release the demo. There are less complicated ways, and I know this way long and hard to follow, but it takes a while to make publically available games with M.U.G.E.N. Hope this helps.
