I recently bought a Yoshi's Cookie Prototype dated 1/19/93 on SNES and I successfully dump the game and want to share the ROM with everyone here, so if you want to try the prototype you can download it on my website, I have also make an article about it (in french, sorry
) if you don't understand french you can always look at the pictures comparaison, the ROM is at the end of the article, so yeah have fun with it !
