- Add "Pikachu Bed" and "Tentacool Doll" decoration unlock options for gen 2 - bugfix for unsafe behaviour - attempt to make the RESET button work for cartridge switching. It failed though. (not reliable). Therefore I just added a warning message instead. - Work on new ScrollWidget for Credits/About screen (Work In Progress)
