Injecting NES / Famicom Disk System Games into Animal Crossing

[@Hunter-R.]

Many people have pointed out that the Famicom Disk System's extra sound channel is not properly emulated here, and all of you are correct! I noticed this after recording and tried for several hours to get it working, but ultimately gave up. I'm 100% certain that Animal Crossing is technically capable of handling this sound channel since all the functionality is there in the code, but I'm not sure exactly how to structure the ROMs to load with this sound channel. If you'd like to read about my troubleshooting on this or if you'd like some clues on how to potentially solve this yourself, I made an entire post about it here: hunter-r.com/posts/ac-fds-emulation/

[@Hunter-R.]

@@CCyoutub Doubutsu no Mori+ actually has both versions of The Legend of Zelda; the cartridge one and the FDS one. In fact, all Japanese versions of Animal Crossing seem to appropriately handle the extra sound channel when playing FDS games. Check the link in the main pinned comment if you're curious on more information.

[@no64256]

​@@Hunter-R. I was gonna make a joke about not having the sound channel ruining my plans to play the superior version of Castlevania 3 in Animal Crossing, but that's pretty interesting. You have any idea why that's the case?

[@raspberry1440kb]

​@@no64256 You chances are actually still ruined, because even in Japan it was a cartridge game, however, unlike the North American and European releases of the game which "ported" the game to the "standard" Nintendo MMC5 chipset, the Japanese release uses a custom chipset developed by Konami themselves called the VR6 that, in addition to preforming functions similar to the MMC5, generates two extra pulse wave sound channels and a sawtooth sound channel.

Can't wait for somebody to get ACE on Animal Crossing and use it to inject a NES game, kind of like the Triforce% glitch in Ocarina of Time

[@TwelveBaud]

Phantasy Star Online has ACE as a Service -- when you try to log in, it actually downloads executable GameCube code through the broadband adapter to try to validate your Hunter License, and there's no meaningful check that it's legitimate Sega code -- so one could easily use that for the setup. Assuming one has a BBA.

[@stgigamovement]

The NES memory card functionality is actually capable of ACE via the patching functionality, and not only can it be used like one would use an Action Replay, but it can ALSO be used to run outright GC homebrew. There are already implementations that do these things. Also, because Animal Crossing can fit into the GameCube's RAM, it means that you could theoretically use Animal Crossing as an Action Replay. It helps that multi-disc GameCube games were a thing. Basically, you could use Animal Crossing as a homebrew loader or Action Replay. Also, if you're loading homebrew off an SDGecko, if you want some trace of legitimacy, use Doubutsu no Mori e+, which was one of the few GameCube games to use the SD Card adapter (identical to SDGecko. It hooks an SD card up to the memory card lines in SPI mode, which is on SD, SDHC, and SDXC cards, but you need homebrew to reach SDHC and SDXC capacity. By-the-book SDUC cards won't work with SPI anymore, but industrial ones will probably have to keep that mode around to not break existing machinery.) Basically, if you use an official adapter with that game (one intended for it. Japanese Pokemon Channel also has official SD support and it also has the ability to be made to run homebrew in the same manner as Colosseum and XD can via saves) you can thus have "justified" homebrew. Oh also unlike using Japanese Pokemon Channel you have the ability to in essence give yourself the means, though of course you need a memory card. If you're clever, you can run GCMM on a Wii without having to install the HBC, and do so using something like a modified str2hax that won't leave any outward signs. Basically, you can go to great extents to "justifiably" run homebrew using Doubutsu no Mori e+ if you so wish, without actually permanently modifying a system.

[@tvbluesun1254]

Since e+ could save to an SD card, I wonder if putting NES/Famicom games on that SD card would work in e+. "QDS 00A170 0050" sounds like it may just be saving 0x0050 bytes from the location 0x00A170, so I wonder if other FDS games really save properly by just copying that value. Maybe only if they save to the exact same position as Clu Clu Land. Even if not, it shows all that would need to be done is locating the correct save positions for each game.

Second thought...how difficult is texture editing in this game? I kinda wanna make a rom that replaces the standard NES games with other games, and replace the games they refer to in the code. Would that be difficult? Probably, but I want to try regardless....

[@Hunter-R.]

Not too hard to accomplish in theory. You can modify the textures pretty easily, and just replace the NES ROM in the files with your own ROM. So if you want to replace the Excitebike NES item with your own NES item, you can just rename the Excitebike item, retexture it, and replace the Excitebike ROM with your own .szs-compressed one. There may be some checksums and annoyances preventing you from renaming items though - I have not tested this.

The points you listed are short sections of the video and are not necessary to understand the video at large. They are simply there to provide a technical explanation. Even if I failed to simplify the video down by explaining every single aspect of each technical jargon, you do not have to understand my technical sidenotes in this video to utilize the ROM injection program or realize what this video is showcasing.

Funfact: Zelda and Metroid where both released for the FDS. Metroid on FDS took advantage of the save feature to save your progress (the cartridge version had a password system while the FDS system had save files.)

[@Octolicia]

10:24 : NOt exactly 100%. See, The Famicom had a built-in microphone in its second controller. The first version of The Legend of Zelda used that microphone to kill the polls voice (those creatures with ear that doesn't react to the flute at all!) So the clue given by the old man in that Polls Voice hates loud noises is useless outside of Japan because the NES had no way to emulate your voice. (But Nintendo knew that so they've reprogrammed the Polls Voice so that an arrow could insta-kill them instead. I tried that trick in the FDS version, it did nothing.)

[@ssl3546]

This is terrific but I don't think the emulator is emulating the extra sound channel on the FDS so the music is wrong. Too bad they didn't go the extra little bit to do that.

[@MechaDragonX]

I noticed that too, but I wonder if they just didn't bother too since Clu Clu Land is one of those direct ports from cartridge with few differences. I don't know what games are available in the Japanese version, but if they don't display the BIOS, they can get away with using the cartridge version of Zelda 1. I can't think of other games in the US version that need FDS support other than Metroid and that's often dropped in Japan since no one cares about it. Their loss 💀

[@stgigamovement]

Actually I've looked at the code and it even supports the FDS audio's FM modulation feature. Something just isn't enabling it.

[@camwoodstock]

out of extremely morbid curiosity: did they bother emulating the Famicom's microphone on the second controller if you have the gull to use a GameCube microphone? the answer is almost certainly "ABSOLUTELY NOT" but we wonder if the game will, at any point, try to stop you before it's too late.

[@Hunter-R.]

I was also curious about this and concluded that the emulator the game uses can handle microphone support if you theoretically force the input to occur. That is, if you modify the game to where every input you press emulates a loud scream coming from an audio input on the second port, the game will appropriately handle it. But, the GameCube microphone (unsurprisingly) does not count as an input for this and there is no other way I know of to get audio input into the GameCube. So, the answer is technically no but not because the emulator can't handle it, but because the input is not mapped correctly. Thank you for the great question!

I couldn't help but notice the FDS sound emulation isn't as accurate. I know what the original Zelda FDS intro sounds like. It seems the emulator is missing the extra sound samples. It makes me wonder if they modified the FDS game that was included on the disc.

[@Hunter-R.]

I’ve replied to a couple comments also mentioning this, and I’ve been working through this since this video released. It’s true that the FDS sound channels aren’t appropriately emulated here, but I’m not entirely sure why. The emulator itself 100% is capable of emulating the sound channels, as it works in the Japanese versions of Animal Crossing and the emulator is the same. But, for some reason, injecting ROMs to be played like this does not appropriately emulate the sound channel. I’ve troubleshooted this for several hours and couldn’t come up with a solid solution.

awesome video! i have a few questions: - what makes Animal Crossing's NES emulation better than WiiVC and NSO? - are there any tools to inject NES games into an N64 Memory Pak for use in Doubutsu no Mori? - what are the limitations of the emulator? i assume it can't handle games with extra hardware (like the VRC6), or any games with crazy mappers (like Action 52). - what are the limitations of metatags? TCRF says they can replace any part of GameCube RAM -- is there a size limit?

[@Hunter-R.]

Good questions! 1. The emulator's code was extracted from the files and was mostly tested against NSO / NES Classic on various popular games released in North America. Things like latency, audio quality, etc. in Animal Crossing apparently matched more accurately to a stock NES running on a CRT than those other services. This was admittedly not tested by me, but by nensondubois who seemed to know more about what they're talking about. It's likely NSO has been updated to be better than this one by now, and I think the WiiVC was near on par. 2. I do not currently know of any tools to inject NES games into the N64 Memory Pak. The functionality seems to exist in that game, but to my knowledge nobody has created a tool to structure the ROMs correctly for the Memory Pak. 3. There are limitations with certain games and mappers, as expected. Nintendo handles these now by including special scripts to further emulate for those specific games, but these are absent in Animal Crossing. Examples of limitations include the 7-BIT PCM choking because the timing is not accurate and MMC5 being only partially supported with no EXRAM. 4. The PAT metatag can indeed patch the game and alter the GameCube's RAM. There is a size limit of 2MB I believe, so more than enough for NES games or custom code.

[@stgigamovement]

You can use the PAT tags to write something into memory capable of loading from SDGecko, or given AC fitting in GC RAM, you could use AC as an Action Replay for other games.

[@Memes_1921]

It would be even funnier if you were playing on a Wii U through Virtual Console injection using Nintendont as a base. So you would virtualize Wii through Wii U, then virtualize GameCube through Wii, then run a port of an N64 game through the GameGube's virtualized hardware that is on the Wii's virtual hardware that is on the Wii U's hardware. Plus the cherry on top, running an NES emulator on an N64 port that is running on a GameCube virtualized hardware that is inside the Wii's virtualized hardware that is running inside a Wii U's hardware (That made me reset my brain for a sec).

@@LVL58Designs I believe the "Super Game Boy" peripheral you're referring to is for the SNES, not the NES -- so unfortunately emulating that hardware wouldn't be possible in stock Animal Crossing.

Did your GitHub pages articles vanish into thin air? I've tried to read the article on the description but I'm getting a 404 error.

[@Hunter-R.]

I’ll fix them today! Sorry for the downtime.

[@ZanaGBYT]

No worries, just was letting you know since they did work about an hour and a half prior to my first comment. So I thought your repo got sniped. I will check later! And thanks for answering that quickly to this minutia!

[@Hunter-R.]

@@ZanaGBYT Should be fixed now. Thank you!

[@Cosmycal]

Awesome video! Subscribed! By the way, what about the GBA link NES ROM and emulator transfer feature? Can it be modified to inject different ROMs to a GBA too?

[@03bgood]

Some of these injected ROM have issues. For example, Kirby's Adventure doesn't save. Kinda weird since The Legend of Zelda actually saves fine.

[@emmastarr5242]

BRB, going to see if this thing can handle those insane Chinese bootlegs that typically only work on real hardware, like Pokemon Yellow, and FF7. :P EDIT: Upon reading these comments, this probably would not work, sadly. I think Kart Fighter didn't use weird mappers though, so I could add that in for shts and giggles, at least...

[@cankechan]

I really like your videos. Keep the good work

[@t80eagle8]

If you could make a quick video guide on how to actually inject regular NES roms on my memory card file (I play on Dolphin emulator) I would be so grateful. I can't figure it out since I have 0 knowledge about python or code or github... just enough to use the emulator and find the memory card save file. Thank you for showing this is possible

[@parknich081]

I'm curious if this emulator exists in Dōbutsu no Mori? (Japanese version for N64)

[@Hunter-R.]

As far as I know the the NES/FDS emulator and their items appear in every version of the first generation Animal Crossing. So, yes that includes Dōbutsu no Mori, Dōbutsu no Mori+, and Dōbutsu no Mori e+! I believe Cuyler’s injection program also has options to inject into the Japanese GameCube games as well, but not the N64 version. I’m not sure if anybody has tried ROM injection on the N64 JP version. There is some leftover functionality to view Famicom ROMs on the Controller Pak, so it probably can be done if I had to guess.

[@stgigamovement]

Yes, it can be done, and on the iQue Player version too.

[@Heather-Br]

I'd love to watch you play NES rom's using Animal Crossing's emulator.

[@ls190v2]

While playing Zelda: The Hyrule Fantasy, I didn't hear what I presume is the FM audio channel playing.

[@stgigamovement]

The game even supports the FM mode, it just somehow needs to be enabled properly.

[@jev1620]

Unfortunately when i created a new nes file which was maro bros 3, put it into my memory card folder in dolphin nothing workd it still says looking for software to play. what i did wrong?

[@The_Wandering_Nerd]

So you can run NES games in an emulator inside of a Nintendo 64 game running in an emulated Gamecube on a PC Wii emulator and it's still a better experience than Nintendo Switch Online?

[@thumbaumrrr]

I have no idea why Nintendo would include an item like this is their game. And the fact that on top of that it is straight up the best nes emulator Nintendo has ever made is crazy. Legitimately feels like a myth i would've believed when I was ten

[@Ambrose_TNJ]

So... Some sick person could actually play Action52 in Animal Crossing, eh?

[@thumbaumrrr]

If you had told me that you could hack animal crossing to access the emulator and play any game on it, and that it was the best nes emulator Nintendo has made, I'd have have thought it was super cool, but the fact that they literally put an item in there that can already do all that is so much cooler. I wonder why they would do this.

[@viniciusgoncalves5948]

So you can play LJN games, Dr. Jekyll & mr. Hyde, Action 52

[@nin10dogmod90]

Is it possible to inject DOOM or Bad Apple into Animal Crossing?

[@enderbo]

you can go even further with nintendont on the wii u the wii u is running nintendont with the built in wii mode which nintendont restores the wiis built in gamecube backwards compatabilty

[@dahjord]

its for the animal crossing memory card it came with a nes game on it iirc

[@RyneMcKinney]

So we can play all 6 Mega Man games through Animal Crossing

[@malick9549]

2:26 how accurate is this compared to the 3ds and Wii U NES emulator?

[@wii1990]

The real question now, which NES games can we get animal crossing to send to a Game Boy Advance via the Advance play feature? My guess is it's as simple as ones under a certain size.

[@JomasterTheSecond]

Huh, I just noticed from Zelda - there's no FDS expansion audio, so that's weird. Does the emulator not support that?

[@Hunter-R.]

A few others have also pointed this out, so I’ll copy/paste that reply here: Indeed it doesn’t emulate the sound channel. I noticed this after recording and discussed this on a forum extensively. I tried for several hours to get the sound channel to work, but ultimately couldn’t figure it out. It’s a shame because Animal Crossing does support the extra sound channel, but it doesn’t seem like you’re able to emulate it properly through this process… This annoyed me a lot more than you’d might think and I spent far too long trying to get it to work. If you’re curious about me troubleshooting this process or you have potential ideas on how this can be solved, you can read about it here: hunter-r.com/posts/ac-fds-audio/

[@JomasterTheSecond]

​@@Hunter-R. Huh, that's very interesting!

[@stgigamovement]

​@@Hunter-R.My guess is that you should try putting random values in parts of the chunks that we don't have answers for what they do and see what happens.

[@BlueEyesWhiteBitch]

This is so cool!! I'm so glad you felt inspired to continue your research. It's really awesome to see new and interesting things being done with some of my favorite old games. Hope you continue to find subjects like this that pique your interest ♥

[@Hunter-R.]

Thank you so much! These are very kind words! I was originally just sharing a couple of discoveries I found interesting, but I tried to put some effort into these videos explaining them. I recorded my first video at like 5AM with my phone mic cause I didn't think anybody would care too much about the video, but I enjoyed hearing the positive reception to it so I tried to improve my audio quality this time. Not sure if I'll continue uploading anything or what my next project will be, but we'll see what happens. Thanks again for the comments and support, though! Again, it means a lot! 🙂

[@samachu09]

I've just watched your videos and they're really interesting! I hope you do more in the close future!

[@ButterFromDiscord]

8:53 bro just fixed their code 💀 Did you give the dev the new code

[@Hunter-R.]

Yep! Cuyler's a great guy and we talked about this program and FDS injection before I made this video. Trust me, rewriting a few lines of his code so I can personally handle obscure FDS games is a minute accomplishment compared to his achievements. He's done so much for a lot of the Animal Crossing games and honestly a good portion of my videos would not exist without him!

[@MadamLava094]

Your videos are excellent! I love technical dives into older games with a lot to tell

[@NoMereRanger73]

Love it! Keep up the great work!!

[@istaffa]

This is amazing! Can you share the save file of your city so we can test this faster?

[@OPP03]

So does this mean that you can play Kirby's Adventure on a Gamecube? I'm asking this because Kirby's Adventure is playable on the Wii via Kirby's Dream Collection and I wonder if you can hyper-BC it using this method.

[@Hunter-R.]

Yep! So in your case you boot up your Wii to play a GameCube game (Animal Crossing) which is emulating an N64 game (Animal Forest) which is itself emulating an NES game (Kirby’s Adventure). Pretty wild stuff.

[@OPP03]

@@Hunter-R. Wow. I guess this game really overdid itself on emulation.
