Essentially a patch that will make the goal sphere always behave as if it were in a vertical level: the "Course Clear!" text will appear instantly, there is no fade and no march - which is more than the usual hex edits do. On the other hand, goal posts will behave correctly in vertical levels (although their usage is no longer recommended - use tall horizontal levels instead!).
I believe this is how Nintendo intended those goals to function, but since the goal sphere has only been used in the only level that ends in a vertical section, it was fine to make it depend on the level type instead.
The hijack at $00C95F spills over into $00C962, which is responsible for part of the Palace Switch routine. In my testing, this caused the Palace level-end music and message to cut short on LoROM, and on SA-1 it broke the Switch routine completely, softlocking the player in the room until dying via the timer running out. This also causes the overworld !-blocks activation to run, but not trigger the respective event, allowing the player to re-enter the level with the Palace Switch disappeared.
The hijack at $00C95F also does not have an autoclean command with it.
