First off, let it be known that I am a HUGE fan of nostalgic gaming, as two of my favorite games of all time are PS1 games.
Second: I don't know a lick about code, or spriting, or really making a MUGEN character at all, so I'm throwing in the towel.
One of my favorite afore-mentioned games is called Legend Of Legaia, for the PS1. Fantastic game, and I wanted ot see if I could at least make a single sprite of the main character. I got close, but couldn't finish it.
So here it is, on the off-chance anyone remembers this gem and wants to take up the cause, my half-done sprite of Vahn. It's a frankensprite of Hon Fu from King Of Fighters and...well, I can't remember the other, but was used for the head cause it had the nicely shaped blue hair.
