@@ -33,6 +33,7 @@ This is a fork of the ultrasm64 repo by CrashOveride which includes the followin
 - haveyourcake, also known as cake screen fix. Made by Wiseguy and ported/PR'd by Cheezepin
 - Tree particle fix (Whether a tree uses snow particles or not is decided via the model IDs instead of the course number)
 - Removed the ifdef hell in `file_select.c` and `ingame_menu.c`
+- Added blake's custom function for object model stuff: `obj_set_model` and `obj_has_model`
 - Coordinate overflow fix by falcobuster. Your levels will render correctly on console and LLE emulators even when using 2x or 4x bounds, while not hurting anything on HLE plugins. **This is automatic now, you don't have to set WORLD_SCALE manually.**
 
 It also uncringes the way that apply_patch.sh works, and removes the black border.
