In this .zip file you will get four mods, which change the player names based on the name of the wad file, for example, Fang becomes Nack, Tails becomes Miles, etc.
And K.T.E could be "Knux", as i'm pretty sure in one of the classic games, that's what showed up. That and Sonic isn't S.T.H, and I just don't really like K.T.E. Initials don't work for names.
*Also, unrelated but apparently Mania and CD just has the life icon and the number of lives, no names show up on the life icon.*
