Some games have mechanisms to manipulate their RNG and it is even used in some TASes.

During this year's SGDQ's TAS block they had a TAS of a Sonic game that used exactly this technique: the bot waited at the title screen the exact amount of frames to manipulate the seed of the game's RNG.

Perhaps a similar mechanism can be used for DK.

Botting the whole game for perfection involves a huge number of permutations since it's a dynamic system. But fastest time is arguably a less complex problem than maximum score since fewer of the RNG events "matter" to time attacks. In a game like Donkey Kong, maximizing one score-relevant event may take away from another.

My favorite RNG manipulation is the King's Bounty TAS:

If you don't get it, here is the summary: To win King's Bounty your hero must find and dig up the randomly-located Sceptre of Order. This normally means questing around for map pieces, combat, recruitment, etc. But with some RNG manipulation it can be placed right outside your starting point.

The run posted actually improved upon the previous one with a new bot that does a more exhaustive search.

Yea, I saw some of the runs during Summer Games Done Quickly that involved some attempts at RNG manipulation although it was not obvious what was happening at all to me watching at home.
