Hot Racing is bootleg clone of Konami's Road Fighter.
The font used for displaying the "CHECKPOINT" message after completing a race contains several unused letters (A, G, M, R, S, V, and Y). Judging by their arrangement, they were likely used to display messages reading "START", "EMPTY", and "GAME OVER".
It's Superman! It functions on the 16-bit port called "High Way Racing" flying through the left screen so it seems to be mostly a leftover or an early idea. Stored with the obstacle graphics.
Early Car Graphics
After all of the CHR banks used by the game, there are 4 unused banks containing early graphics for each of the playable cars.
The positions of some pixels on the roof of the car's driving sprite were altered slightly for the final. Both sets of crashing sprites are identical.
The F1 had a completely different design which was changed for the final game.
The headlights were shrunk on the driving sprite and a slight bit more detail was added to the back of it. Both sets of crashing sprites are identical.
The front of the car's driving sprite was made symmetrical and more detail was added to the back of it. Both sets of crashing sprites are identical.
|Hot Racing||Metro Mania|
A basic hack of Hot Racing named Metro Mania can be found on many recent Plug & Play Famiclones. Only the title screen logo is changed, the "Hot Racing" text on the vehicle selection menu remains unchanged.
