With the links + Best i can explain.
https://www.mediafire.com/file/lbd3wg2jahx5z8x/MUGENMarioWarnerESQUE.zip/file : A much more up to date SSB Mario (Via: Shorter sprites than being the same height as Warner's Luigi and some polishing up on most of the more cruder ones + AI built of an AI patch) vs the OG release back in 2015, in addition of a winmugen, 1.0 and 1.1 def. It also has a Smash Mod.def
https://www.mediafire.com/file/lfuyfph1cxdrw2o/MUGENWarnerLuigiEdit.zip/file : same as the above (Most sprites are mostly unchanged but with some new one added in a few sprite errors fixed.) but with a different default palette and various adjustments. (Also instead of a higher pitched mario. Its now the Actual Luigi voice clips distinction.)
https://www.mediafire.com/file/tv5pemexduplia4/MUGENApersonAndWarnerLuigiEdit.zip/file : Basically my lil AI edit of Aperson's (AI may not be complete in smash mode. But regular mode works fine).
