Pokemon Snakewood for Game Boy Advance GBA
One of the latest fan-made games of the popular series. In a nutshell, this is a modified and horror version of Pokemon Ruby, with an entirely new dark story which involves zombie Pokemon, even some new ones especially made for the game!

I've included a case and compiled a custom designed insert for it also. Printed on a professionally graded paper.
Rare to find in physical form

(Just a side-note, avoid picking berries in Snakewood as it can cause a freeze/crash)
