What is Nitro Revolution?
Nitro Revolutions is a romhack with the goal of bringing the content from Mario Kart Wii to Mario Kart DS.

Currently implemented features:
  • Custom Coded MapObjects such as the cow from Moo Moo Meadows and the Wiggler from Mapple Treeway​
  • Kart Recolors for each character like on Mario Kart Wii, in addition to being able to use every vehicle with every character (such as funky kong on the wild wing).​
  • Aims to be hardware compatible​
Planned features:
  • Pixel art local maps with correct icons
  • Redesigned bikes into karts/trikes
  • Mega Mushroom Custom Item that will replace the boo effect.
  • Download Play compatibility (HUGE MAYBE, if it ends up happening will require a custom firmware to work, please read this for a better explanation on the subject)
What won't be in this romhack?
  • Bikes. This is for technical reasons, I know how to make the game load a different player model based on the kartID, however this only would bloat the file size of the archive that contains it. Since bike won't be in neither will inward drifting be
  • Tricks. They are simply not worth the effort of revisiting the already done tracks to change the collision to add the trick trigger. Plus I don't really see the point of the gimmick considering it was mostly added to have motion controls. (July 3rd, 2023 Update) Due to the recent efforts of fellow community members Prellit and Garhoogin this might no longer be the case.
  • Mario Kart Wii Drifting. Snaking is way more fun, period.
  • Motion Controls. Quite obvious considering the console does not have any motion sensors. I've heard of the DS Motion Pak before but I simply think it's not worth the effort coding motion controls when you have to hunt down an obscure addon. However I heard it was possible to map the 3ds gyro to ds inputs trough an ar code and twilight menu, so we'll see about that.

(Different romhack but same track)






The Latest ROM can be found here and here

I hope you guys enjoy what we have made so far! ^_^
Note: We used to have custom music but the sound archive got corrupted, I'll fix asap
Note 2: Please report any red screens you get.

Good job! Is this the main source to follow progress or do you guys have Twitter or Discord or something like that?

Having issues with toads factory, it still has the minimap and pathtracking of luigis mansion, so the lap doesnt count, and if i fall off i respawn in the void, and the cpus just drive off of the edge due to incorrect pathtracking

    i said i was sleeping...
  • BakerMan @ BakerMan:
    sleeping with uremum
  • K3Nv2 @ K3Nv2:
    Even my mum slept on that uremum
  • TwoSpikedHands @ TwoSpikedHands:
    yall im torn... ive been hacking away at tales of phantasia GBA (the USA version) and have so many documents of reverse engineering i've done
  • TwoSpikedHands @ TwoSpikedHands:
    I just found out that the EU version is better in literally every way, better sound quality, better lighting, and there's even a patch someone made to make the text look nicer
  • TwoSpikedHands @ TwoSpikedHands:
    Do I restart now using what i've learned on the EU version since it's a better overall experience? or do I continue with the US version since that is what ive been using, and if someone decides to play my hack, it would most likely be that version?
  • Sicklyboy @ Sicklyboy:
    @TwoSpikedHands, I'll preface this with the fact that I know nothing about the game, but, I think it depends on what your goals are. Are you trying to make a definitive version of the game? You may want to refocus your efforts on the EU version then. Or, are you trying to make a better US version? In which case, the only way to make a better US version is to keep on plugging away at that one ;)
  • Sicklyboy @ Sicklyboy:
    I'm not familiar with the technicalities of the differences between the two versions, but I'm wondering if at least some of those differences are things that you could port over to the US version in your patch without having to include copyrighted assets from the EU version
  • TwoSpikedHands @ TwoSpikedHands:
    @Sicklyboy I am wanting to fully change the game and bend it to my will lol. I would like to eventually have the ability to add more characters, enemies, even have a completely different story if i wanted. I already have the ability to change the tilemaps in the US version, so I can basically make my own map and warp to it in game - so I'm pretty far into it!
  • TwoSpikedHands @ TwoSpikedHands:
    I really would like to make a hack that I would enjoy playing, and maybe other people would too. swapping to the EU version would also mean my US friends could not legally play it
  • TwoSpikedHands @ TwoSpikedHands:
    I am definitely considering porting over some of the EU features without using the actual ROM itself, tbh that would probably be the best way to go about it... but i'm sad that the voice acting is so.... not good on the US version. May not be a way around that though
  • TwoSpikedHands @ TwoSpikedHands:
    I appreciate the insight!
  • The Real Jdbye @ The Real Jdbye:
    @TwoSpikedHands just switch, all the knowledge you learned still applies and most of the code and assets should be the same anyway
  • The Real Jdbye @ The Real Jdbye:
    and realistically they wouldn't

    be able to play it legally anyway since they need a ROM and they probably don't have the means to dump it themselves
  • The Real Jdbye @ The Real Jdbye:
    why the shit does the shitbox randomly insert newlines in my messages
  • Veho @ Veho:
    It does that when I edit a post.
  • Veho @ Veho:
    It inserts a newline in a random spot.
  • The Real Jdbye @ The Real Jdbye:
    never had that i don't think
  • Karma177 @ Karma177:
    do y'all think having an sd card that has a write speed of 700kb/s is a bad idea?
    trying to restore emunand rn but it's taking ages... (also when I finished the first time hekate decided to delete all my fucking files :wacko:)
  • The Real Jdbye @ The Real Jdbye:
    @Karma177 that sd card is 100% faulty so yes, its a bad idea
  • The Real Jdbye @ The Real Jdbye:
    even the slowest non-sdhc sd cards are a few MB/s
  • Karma177 @ Karma177:
    @The Real Jdbye it hasn't given me any error trying to write things on it so I don't really think it's faulty (pasted 40/50gb+ folders and no write errors)
  • DinohScene @ DinohScene:
    run h2testw on it
  • DinohScene @ DinohScene:
    when SD cards/microSD write speeds drop below a meg a sec, they're usually on the verge of dying
