CFC4 freeze: Difference between revisions

Specifically, the value stored at address CFC4, storesknown as wFontLoaded, acts as a check to see if athe font is loaded, and is thus known as wFontLoaded. If the firstleast-significant bit of this address is set, thus beingdenoting an odd value, then whenwhenever the game needs to load a new tileset into VRAM, the game copies tileset data during VBlank. If the valueaddress iscontains an even value, then data is instead copied while the LCD is disabled. BecauseIf this valueaddress is setcorrupted to 1an odd value during battle, then when exiting the battle, the game goes through a code path that resultscauses init waitingto wait for a VBlank interrupt that will never arrive, due to the LCD being turned off during the battle transition from battle to overworld.
