Pokemon Backwards Edition / Der Erif (Hack) GBA ROM

Description:

This is a pretty old hack of Fire Red with the concept of “What if I moved through Kanto’s cities in reverse order” like Pallet–> Cinnabar–>Fushia–>Saffron –> Celdon, etc back to Viridian.

Major changes include new environment landscapes (For example, Cinnabar is an oasis and the sea became a desert) With this, Pokemon encounters have been adjusted to fit the new habitats.
HMs are also obtained in reverse order and power has been adjusted with Surf being the weakest shit you have ever used and Cut being one of the best Steel type attacks you can get.
