All Bubbul Gems? All caves implies we would just have to get them on the map

jesus christ

I have an OEM n64 controller with a hyperkin adapter, but the c-buttons read as analog inputs (z-rotation+ etc), this is an issue because i have to use dpad-up to use savestates on the practice rom since the analog input cant be left-right or up-down at the same time. is there any fix to this issue?
