Database match: Mario Kart 64 (USA)Hack description
This patch for Mario Kart 64 (USA/NTSC) gives the CPUs in Grand Prix mode some of the same items a human can use. CPUs can finally fire shells, use multibananas, and triple mushrooms. Normally CPUs can only use single bananas, stars, ghosts, fake item boxes, single mushroom boosts, and lightning. They spawn the items all at the same time up to three times per lap and draw from their own item probability tables. With these new items the CPUs can use against you, GP mode is now more challenging! CPUs never used shells, multi-bananas, triple mushrooms, or golden mushrooms. Through an exhaustive look into the game's code, micro500 and I were able to deduce how CPU players spawn items. It turns out that a lot of this code never made it into the final game, and has remained hidden for over 20 years in the inside the game's rom. Some of it it was never fully debugged or finished. This patch takes most of the unused CPU item spawning code that works and adds it back into the game with some custom assembly code. See the readme.txt for more details.Screenshots

| Positive vibes and little bug reporting. | nad84 | 2022-05-22 | Version 2.7 |
I'm very glad this romhack was just updated very recently. I'm really happy you made this hack ever possible. I know the original game may turn really easy and even on 150cc / EXTRA if you're an experienced player with Mario games, but this hack actually makes the whole game MUCH but MUCH more fresh as used to be... I have played like 3-4 times already and the 3rd one I had to just quit because I got frustrated and couldn't even reach top 3 in STAR cup. But I mean getting frustrated in a very good way. Like, the game really turned into an interesting challenge because the whole set of items being used. Really appreciate you made this possible. I would like to report just only two bugs I have encountered through the gameplays. The first one has happened to me like 3 times already, but it's chance to happen is something like 1-5% of time ? The thing is that sometimes I have had a green shell to shoot behind me and the moment i'm pressing Z trigger + down, so when I stop pressing Z then the shell should be shot but instead, the shell keeps being behind me and so then I have to press Z again and stop pressing while keeping down pressed in order to shoot properly. Not sure why would this happen, maybe the engine is out of memory ? But this issue seem rare to happen for me, at least. And since you can get several items in one map from Star cup so I have experienced this doesn't happen most of the time. Second bug that I found once was the fact I had one green shell moving around me (coming from the 3 at once that can be gathered) and I had one of those orange mushrooms that boost you several times. So, the moment I shoot the last remaining green shell so right then I wanted to trigger the orange mushroom but even then, it dissapeared from the slot on top ! If I remember correctly, another time I had a STAR instead of orange mushroom and I think it happened the same. I just shot one green shell but right away when I wanted to use the STAR then, magically just dissapeared ! Both of these bugs seem kind of rare to happen, but these situations definetely didn't use to happen in the original game. If can be addressed, I hope can be fixed up. I hope you can keep updating this very interesting mod. It's definetely my favorite way now to play Mario kart 64. Good vibes to you or anybody else who's involved into this mod. | |||
| How it should have been in the first place(?) | Pr1me | 2021-06-12 | Version 2.5 |
As a veteran of this game, this hack adds functionality that I believe should have been there all along. The CPU opponents now put up a real fight - the game isn't impossible as others have said, but it's much more of a push to get 1st place, and racing in general is much more exciting. You're always on edge as to when you might get hit (made more tense by the fact you can hear other racers when they fire red shells) and there's much more of a tactic of holding items behind you. Rainbow Road in particular becomes a real marathon challenge. As mentioned though, this hack definitely isn't for beginners. I imagine if Nintendo had implemented these features originally, they might have toned down the rubberbanding. For anyone who's been playing for decades though, this is unmissable! | |||
| How a walk becomes a challenge! | Poe | 2020-08-15 | Version 2.5 |
Mario Kart 64 was my first game for the N64 and it had been for about one year before I got another one. I was always wondering why the drivers, controlled by the computer, couldn't use further items such as the player. It made it really easy on each speed level to win again and again. If I remember right Mario Kart Double Dash for the Game Cube was different again because the computer could use far more items - and that's how it should be. Now, 20 years later, I'm quite impressed that this issue was finally changed. Since the computer is on par with yourself it's much more fun and even more challenging. So thanks a lot for this great hack and additional enjoyment! However in my opinion this hack is recommended for advanced players. New players, or such who play it for the first time, might be a little frustrated at the outset. But if you gain more experience it shouldn't be any longer. | |||
| Amazing | realgeizt | 2020-08-14 | Version 2.5 |
Great way to spice things up and have a new experience. Random factor is big and hilarious. Great job and idea! | |||
| Breaks the game | RStffan | 2020-04-24 | Version 2.5 |
Neat idea, but the game clearly wasn't designed around it. I can barely get 3rd place on 50cc. | |||
| Wait what | Thirteen 1355 | 2019-11-23 | Version 2.5 |
I didn't even realise, until just now, that CPU opponents don't use every item. This is a definite improvement. | |||
| Works as advertised | mariokarthero | 2019-11-21 | Version 2.5 |
This hack makes for a more complete Mario Kart 64 experience for me. Kudos to the hacker for reinstating a feature I had never realized was missing until now. | |||
