A funny, cute, and FUN game

Hi, cool game, great idea!

Can I buy a game on cartridge from you?

There was only one cartridge ever made and it was a gift to someone, so there aren't any available for sale. You can buy a blank cart from a third party and flash it with the downloadable ROM for yourself though.

It uses MBC1, ROM banks 0,1,2,3 and no RAM banks.

Here is what I used. They can flash the ROM for you if you email it to them. Any of the MBC1 firmwares should be fine, no battery required.

If you do that, I can share cartridge label graphics.
