ROM Hack [Release] Ultimate NES VC Injector for 3DS

[FrostyDialga]

I'm having issues getting Super Mario Bros 2 & 3, and Metroid working.

SMB2 will load the to title screen but when I press start the screen turns black and the audio still plays.
SMB3 loads a grey screen and locks up.
Metroid loads the title screen but when I press start the screen is a mess of broken titles.

Spoiler

I have mario bros3 mix working and i just injected it normally are you using a bad rom.

@Asdolo you might like this: https://github.com/AuroraWright/Luma3DS/commit/f3322bd003062f2333d5aaf2d1d62bb341bf9f63

with this commit, NAND titles may not need to be encrypted. so now you can probably skip encrypting the dlp child, provided both users are using a version of luma that has this.

it currently needs fixing, though I think it will work soon. zerokey works though!

Is this working on the last luma release?

turns out no-crypto doesn't work in NAND. zerokey does, and you can do this on your PC (the key is all zeros hence "zerokey"). this works as of v6.6, latest release right now

Hmm, where's the signature? Can I just byte-fill some offsets with zeros and the CIA comes zerokey-signed? Or is there a tool for that?

you're confusing signatures with encryption. the NCCH regions (exheader, exefs, romfs) are zerokey-encrypted. that means the key is (in hex) 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00.

if you are using makerom, I think all you need to do is set EnableCrypt to True and it will use zerokey.

So this works with any .NES file or is there a list compiled somewhere?

Quick request if it's possible, could local multiplayer be implemented? Super Mario Bros. 3 VC on 3DS had it, not sure if any other titles did but it's a really nice feature, way better than L+R+Y

Is this normal? It happens on all of the injectors.
Also, seconding the above post.

It should work with most. There are some games, such as bootleg ones, that use mappers that aren't compatible with Nintendo's VC emulator. For the most part, the injector will tell you if you try to load an incompatible game.

For some reason the injector looks like so

Any clue how to fix this?
This replicates the preview onto the 3ds system and does not work at all.
Thanks

EDIT: nvm solved it, had to switch my scaling back to the smallest as a temporary fix. Great tool tho!

It'd be nice if you had an About section, listing all the tools you use and people who gathered the info. Such as the NES to TNES converter by hippy dave, the XML file from MAME, the extensive research by me...

I was also wondering if its possible to do multiplayer like in 'river city ransom'?

as-well I wanna ask does any one know where I can get a hold of Goemon 1+2 for Famicom ? cant find them anywhere and goemon doesn't work in this injector tool.

Managed to convert a FDS file to QD and injected it in. Can't swap sides of the disk though.

 

[seijiro]

Whenever I try playing Battletoads using the VC injector it gets stuck on the intro scene. Is there a way to fix this? Does anyone have a working Battletoads NES .CIA I can have?

I think that this for swap side disk it need a .patch edited
I tried medroid fds(this game have official replease so) ... But cant swap sides too
I used roms of famicom remix game(all games run perfectly)
Kid icarus too (.nes rom not run )

Tried with Grand Dad (bootleg), worked

Now I'm gonna take my sister's 3ds and mess up with all it's NES VC and replace all of them by bootlegs

 

[rafasaur]

It keeps crashing when I try to open the ROM file. Any hints?

Send me the error message

I made a whole bunch of NES roms, when I try to install them from FBI, a few will install properly, but then some will overwrite the previously loaded game (game and banner change, icon stays the same, no new software message appears on screen). Would I be correct in assuming this is because I didn't close the application every time, and for many scrolled back to page 1 and just loaded a different .nes file? And if so, is there a way to correct them now?

Thanks in advance, and for coding all these awesome injector programs!

Minor issue i found, opening it once but using it multiple times (Example: Opening one ROM, making a cia for it, loading a new one by going back to Step 1) causes them to have the same Title Key. Though i managed to fix it by closing it after each cia creation
