Homebrew [DISCUSSION] New Super Ultimate Injector (NSUI)

Robin64 · Oct 22, 2019

Man, I love absolutely everything about this program, and I've been using it quite extensively for the past few days since DarkAkuma added .bin generation to SFROM Tool.

I just have one gripe, and that's that the banners it generates are really not accurate to official Nintendo VC releases. Is there anything out there that can generate them to look like Nintendo's ones, or am I going to have to dive into Photoshop and do it the long way?

Edit: Found this, going to give it a go.

what settings did you use to inject?

I'm struggling to make any working CIAs. I've been reading and I've read a bit about seeds. I don't have those. Do I need them? All I'm doing is making the CIA, installing it with FBI and then trying to run it. Each one shows the 3DS title and then goes to an error. This is the error I get for SNES VC CIAs:

Exception Occurred.
Type: 1
fsr: 0x00000805
far: 0x0e000000
fpexc: 0x00000000
fpinst: 0x00000000
fpinst2:0x00000000
...

And then some more numbers. Am I doing it wrong?

You don't need seeds unless you were installing official VCs.

At the risk of asking the obvious, have you checked that the files weren't getting corrupted on transfer?

Thank you for this, however, I have a problem, Whenever I try to export a CIA with a ROM hack patch, it gives me an error saying "invalid patch file format"

The hashes match up, so it isn't that. I'm running 11.4 EmuNAND.

I did notice that a 256kb ROM can become an 13MB CIA. Is that normal? It seems big.

It probably is, the emulator in the VC takes up some space on its own. For instance, GB VC is 9.7 MB for a 512 KB rom.

For GBA VC, the cia isn't much bigger than the rom, because there isn't actually a lot of software that goes with it, the 3DS just passes the rom over to AGB FIRM and it handles the rest. For the other VC though, there needs to be an actual emulator, and the emulator is bundled in each individual app (which is a bit silly, but I digress.)

I'm not sure about the crashes, though. I know that SNES VC wouldn't work on O3DS, but as far as I know you're using a N3DS, so it can't be that.

I did read somewhere that the firmware updates from game carts can be different to those from the internet (in particular something to do with the GBA firmware), and my N3DS was most recently updated via a cart. I wonder if it's missing something that it needs for SNES VC.

game cart updates dont include the side apps like the music player or internet browser. Dont think it affects anything like this.

I tried a SNES CIA that I didn't make and it gave a different kind of error. This error looks like a Luma3DS one, and it says:

An exception occurred
Processor: Arm11 (core 1)
Exception type: undefined instruction
Current process: loader (0000000000000000)
...

And then numbers. Is this any more informative?

retrospect · Nov 7, 2019

I have a thought. Are there are freely distributable SNES ROMs (like hobbyist games)? If so, I could download it, make it into a CIA, and get its SHA-1 hash. Someone else could do the same and we could compare hashes. That way I'll know if the CIA is good or bad.

Hi! I have a problem when creating a Pokemon Sapphire into my 3DS. The issue is that the real time clock is not working. Everytime I start the game I get a message saying that the internal batery is empty. Strangly, when I create a Pokémon Ruby or Emerald CIA, the real time clock works perfectly. I'm using a spanish rom and I have try with differents roms but still doesn't work. Any idea?

Ignore the fact this is for a different Pokemon game let alone a romhack.

GBA VC injecting Pokemon - Liquid Crystal with working RTC for the 3DS.

Look at the red box for the Rom Save type.

@Feffe Is there any possibility of extended ROM support becoming possible, or is that just not going to happen with the 3DS VC?

Unlikely, I think this would require reverse-engineering and modifying the emulator itself. Paging @DarkAkuma for an educated answer.

TL;DR

Don't hold your breath. I feel that, odds are, it's not realistically going to happen.

Actually. I've been specifically looking into this lately with the SNESClassic and Switch emulation code. (The 3DS code is just a different fork of the same code). It seems to be as I have suspected. The emu will just not map the extended region of the ROM. ExHiROMs for example are seen as just normal HiROMs, and have their first 4MB mapped. But that's it. You will find that some hacks like Crimson Echoes will boot because most of their code is in the normal region, but as soon as the emu tries to access the extended region it will crash. Nintendo would had to have specifically coded support for ExHiROMs, but as there are only 2 that were Japan only, they didn't.

I'm going to be looking into the feasibility of a hack soon, but realistically it would not be a normal simple hack like changing a 4 to a 6. I'd have to write a whole new subroutine for the extended region, and get the regular routine to access it. For that I'd have to better understand such mapping, understand every line of the emus code, find out if such extensive hacks are possible with things like this... oh, and I'd first be doing it for Switch. Maybe SNESC. But I haven't even been able to disassemble the 3DS's emu code yet. Assuming I could, it would be further down my list.

As for ExLoROM, or at least S-DD1 ROMs as I have been so properly instructed on the difference lately. Well. Of the 2 S-DD1 ROMS, SFA2 is supported. And Star Ocean did not have support added until SNESC. I'm curious to know why SFA2 will boot on 3DS/WiiU, but not SO. But it's not something I will probably look into for awhile. It could very well just be that while SFA2 is a SDD1 ROM, its still only 4MB technically. So not exactly an extended ROM. While SO is 6MB, so technically an extended ROM. And thus wont boot for the same reasons as ExHiROMs.

EDIT:

In the Switch emu (and likely the others), there is a check that excludes even trying to load any ROM whose header says its higher than 48mbit. So this itself will be the cause of some hacks not booting at all.

Hey, i'm trying to inject the fds version of Metroid into my 3ds with this program, and have made some progress, but when i select the injection method as "FDS Virtual Console", it says in the limitations section that i need a custom vc patch to trick the disk swapping. anyone have an idea where i can find this patch?

Most likely, it needs to be written specifically for Metroid, since every game is different. If nobody else has done it yet, such a patch probably doesn’t exist.

There is an English translation patch for this game made by AlanMidas.

Although it's a little hard to find a clean rom dump, you'll most likely find the header-less version that is:

Metroid (Japan) (v1.2).fds (CRC32: 1AD64B0F | size: 131,000 bytes)

Add the 46 44 53 1A 02 00 00 00 00 00 00 00 00 00 00 00 header at the beginning with a hex editor to create the header version (AA49947D) before IPS patching to get final romhack (A737F014).

***

This can be played on the VirtuaNES for 3DS with the required bios, sysdisk.rom (5E607DCF | 8.00 KB), as this emulator does have disk swapping menu control.
However, the sound accuracy is noticeably lower compared to official FDS VC. Listening to the spooky, outer space introduction on my headphones, I found the reverberation and dynamic range are softer and flatter.

***

Another way to play this game with better audio that's just a tad less accurate versus the official FDS VC is to inject using this NSUI setting.

Famicom Disk System CIA

Injection Method: RetroArch FCEUmm forwarder

Make sure to provide the needed bios.

Tools → Options... → Bios → Famicom Disk System Bios (md5: ca30b50f880eb660a320674ed365ef7a):
- bios\fds_bios.bin
- This is the same file as the previously mentioned, sysdisk.rom.

At the disk swap screen, press (R)-shoulder, (L)-shoulder, (R)-shoulder to change between disks B and A.
