![[TAS] Super Mario 64 DS - Bob-omb Battlefield - 255 Coins @Really_Tall](https://i.ytimg.com/vi/pMhRNbr_2A0/maxresdefault.jpg)

In this video I collect 255 coins in Bob-omb Battlefield. This is the maximum amount of coins possible.
Update: see here for an easier method that's viable for getting 255 coins non-TAS: youtube.com/watch?v=B9CoGKLpl8A
Previously, 229 coins was the thought to be the maximum possible, and had stood as the record since 2005 (cyberscore.me.uk/chart/12812). Then on 2016-05-23, I discovered bob-omb coin duplication (youtu.be/YlXINkZs1PE). This required a shell, owl, fly guy, or spindrift. As there is only one shell in BoB, this raised the total by a single coin, up to 230. And then yesterday, 06/06/16, I discovered that on the E and U 1.1 versions, goombas can be used to cancel eating an object (youtu.be/45ahej0bE9k). This means that the infinitely respawning goombas with caps can be used to perform bob-omb coin duplication, allowing for infinite coins!
To start off, I set-up my file by unlocking Mario and Wario, but not Luigi. It isn't necessary to not unlock Luigi, but it means that I can get 4 more coins without using bob-omb coin duplication. Wario can be unlocked without Luigi by doing a glitch called Mirror Clip (youtu.be/t4OV8sLUAJA).
Wario needs to be unlocked so that I can use the goombas with Wario caps to perform bob-omb coin duplication. I also select Star 4, Big Bob-omb's Revenge, as this star allows the most coins to be collected. This is because it has the koopa, a couple of blocks with coins, and an extra bob-omb that falls from the sky which is used for a 5 combo with eggs.
I enter BoB as Yoshi with Mario's cap, and begin to collect coins normally.
At 2:26 I reach 86 coins and begin to do egg combos. This is an intended mechanic: Yoshi's egg can hit up to 5 enemies, and produces coins for each one. If the egg contains a goomba then you get 1 coin for each thing you hit, if it contains a koopa you get 5 coins. This is in addition to any coins usually given by the enemies you hit, so I get more coins the first time I do this. It is possible to hit more than 5 enemies, but coins are only produced for 5. I lure the bob-ombs in a specific way so that the egg hits 4 bob-ombs, and then attempts to travel to the bob-omb at the lower section and hits the ledge, producing a 5th coin. This maneuver will be repeated for every goomba without a cap, and the koopa.
At 3:50 I reach 111 coins, and perform bob-omb coin duplication for the first time. This works by landing on the goomba as I eat the bob-omb, which confuses the game. I can then move on the ground to swallow the bob-omb, giving me a coin. However when the bob-omb respawns it still has its coin: this can be repeated due to the goombas with caps respawning infinitely, allowing for infinite coins.
At 4:28 I reach 120 coins, and perform bob-omb coin duplication with the other goomba the Wario cap appears on. The Wario cap alternates between these two goombas, and they are both near enough to bob-ombs for bob-omb coin duplication to work, so it's most efficient to use both of them.
At 10:08 I reach 190 coins, and perform bob-omb coin duplication using the shell, the only method that works on all versions. This is very similar to using a goomba.
At 11:40 I reach 223 coins, having collected nearly every regular coin available. Despite having been doing bob-omb coin duplication frequently while collecting the other coins, I still need to do it 23 more times, to be able to reach 255 coins.
At 15:46 I reach 246 coins, having done bob-omb coin duplication for the last time. I now collect the two coins from the bob-ombs I have been using to duplicate coins, 6 coins from two blocks that I needed the bob-omb I was using for bob-omb coin duplication to destroy, and finally the 255th coin from a lone goomba near the top of the hill, which I couldn't do an egg combo with due to it wearing a cap. I use a heaven's portal to get up to it just for fun.
A few things to note:
- The pole that the chain chomp is tethered to does not produce any coins, unlike in SM64.
- Bob-omb coin duplication is used 36 times in total.
- Collecting any more than 255 coins will just keep the counter at 255: the counter is a single byte. You can collect infinite coins with this strategy if you want to though.
- This strategy only works on the PAL and 1.1 versions, and not on the 1.0 version. I don't know if it works on the Japanese version, Korean version, or any other versions.
- On the 1.0 version, and any other versions where a goomba can't be used to do bob-omb coin duplication, the maximum coin score possible is still 230 coins.
This was played on the PAL version, and was tool-assisted. 3616 re-records were used.
