As some of you may have noticed, if you manage to get your hands on this full ROM, when you press the select button, you'll notice that these numbers change. 15>28 to 01>14. But what does that mean?

By default, it's 15>28, and if you change it to 01>14, you'll be disabling the game's perks. For example, if you take the gun or star twice on your last tank level, you won't be able to burn grass. Also, the boat item will disappear, which means you won't be able to use the boat to cross the river or as a shield.

Is it possible to create a new category for 01>14?

I don't see the need to do so. Anyone who wants to argue otherwise? Honestly, I see it as a waste of time to create more leaderboards and have people come in who don't even give an average effort to play well and sneak into first place the easy way. There will be no new categories until 2025. The only exceptions would be to expand a new category whenever a bug or glitch is discovered.
