ROM Hack [SNES VC] Informations about the Header and injecting

[xXDungeon_CrawlerXx]

Hey Guys,

I've collected some informations about the Header of the data.bin which contains the SNES-Rom.
This informations should help you to understand what's needed to inject a SNES-Rom into the data.bin

If you've some more informations about this, please tell me, I'll add them to the image.


thanks to @Team Fail for helping me with this

What I'd like to know is what that ROM footer is all about. When I rip ROMs from the VC containers, the audio tends to be garbled. Injected ROMs work fine though. I wonder if those are patches or something...

good question. I don't know a lot about SNES Roms, probably someone else can tell us what this footer is doing

Is it possible Nintendo is doing something similar to what they did on the Wii, a separate file (in that case pcm, see: https://gbatemp.net/threads/rom-pcm-and-var-files.261441/) for the sounds to improve performance? iirc on wii injecting the regular rom worked, even though the vcs from nintendo used pcm files for sound.

It would be good to have a full working guide on how to inject a rom.

I'd love to make a Final Fantasy VI VC or Dragon Quest V VC.

I haven't had any luck inserting FFVI as of yet, so it won't work, sadly.

That seems to be somewhat important, but I don't know what it's for, so keep it where it is for now - just repoint the ROM data. There's some footer data as well, but I don't know what it is.

I've been getting .sfc roms and placcing the header on it and it seems to work fine

It might be like the N64 Virtual Console. We might have to wait for the "right" legit VC release to find a game that will allow FFVI to work. Perhaps Earthbound?

I've seen pics where someone already got Lufia 2 Rise of the Sinistrals working. Maybe using whichever game they used for that?

I tried injecting it into EUR EarthBound to no avail.

I tried that but Mario RPG uses a special chip the VC doesn't emulate

 

[RahFah]

Do you have a tutorial for inject snes roms on VC? I searched, but I just found pieces of information

 

[Asia81]

what is rom footer?

 

[ElyosOfTheAbyss]

Super Mario Kart uses a chip so what if we can enable chip emulation in the header of data.bin? (Cartridge Chips not Dorito chips)

 

[xXDungeon_CrawlerXx]

what is rom footer?

Something unknown to someone like me (a non SNES-hacker-thing)

 

[ElyosOfTheAbyss]

With HiRoms not the whole rom is injected

what is rom footer?

I'm not sure what it is yet, I can't seem to make heads or tails of it, but it seems to be of importance if there's a pointer to it from the header. I wonder if someone could zero out that pointer what would happen...

HiRom data.bin Doesn't seem to have a footer. In fact it looks like not the whole ROM is injected
