Oh, I should have assumed you worked on original hw. Feeling silly now. Any games I might have heard of?
A few months ago I was diving into unreleased prototypes and I played a bit of both games. On Waterworld, someone released a rom hack: https://www.romhacking.net/hacks/6644/. Wacky Races and I go WAY back, and I believe that you captured the look and feel of the cartoon. The music is awesome too. It seemed so close to finished, and way better than most cart racers. How close was it to it's final form?
it was pretty close to completion. Probably one or two bugs to iron out (needed some playtesting) and localisation. We were playing a LOT of Mario Kart at the time, so I tried to capture some of that, though the lower frame rate didn't help.
I did the underwater section on Waterworld.. quite an interesting project that. I think there were four programmers, one on each different section, all working independently. Such a rush job :)
