Bootleg cartridge for SNES, a rom hack of Nigel Mansell's World Championship Racing called "Ayrton Senna".
It just translates the game, changes the opening movie and has Senna giving you tips about the tracks.
I also have a PC game called Luna-C, in the box. I got it many many years ago and there's literally no info about it online, it's kinda like Super Monkey Ball but uglier. It's kinda fun though, I liked it when I was a kid. Was pretty surprised to find out there are no downloads up for it, at least my disc still works.
Looking up the publisher's name gives no good results.
