A item tracker when opening the map in the overworld
Use asar assembler from here https://www.smwcentral.net/?p=section&a=details&id=19043 and a random game from here https://alttpr.com/en. When you open the map in game it shows the number of items for locations. It also displays the number of items obtained. This code uses save ram for almost all items so you should use save states with this. The tracker doesn't work well with retro variation different locations.
