ROM Hack [HELP] SNES VC Decrypting doesn't work

[Mr.ButtButt]

the only way i was able to extract/rebuild snes games was through the ba-GUI-nner tool.
However since it was upgraded to 2.2, it doesn't extract for me anymore..
So what do i do?

Try using CTR tool to extract i honestly never used Ba-GUI-nner tool at all

Sadly enix games like terranigma or illusion of time doesn't work. I got around the pal > ntsc problem but there is no sound and graphic problems.

terranigma works

terranigma works

US yes, EUR not > PAL to NTSC breaks it.

yeah tried german version didnt work either

i noticed more progress has been happening such as properly fixed SoM screen, SD3 working, etc etc. has any progress occurred with star ocean or super Mario rpg?

 

[Fugelmir]

A lot of the fixes for games like illusion of gaia and SoM involve changing a few bytes in the internal header of the snes rom itself.

Games with the sa1 and sdd1 chips dont seem to be supported.

I also cant get games over 4mb in size to run at all. For example, dragon quest 3 is a 4mb game, but the english translation expanded it to around 6mb.

Interestingly, I managed to get satelliview games working by adding garbage data to artificially increase the rom size.

At this point, im waiting on the rumoured JP release of marvelous -- Which is an epic snes rpg that uses the sa1 chip.

So I've been super busy and have had basically 0 time to work on my SNES injector. However, I finish all my exams next week, so hopefully if I have a bit of spare time between unpacking and working, I'll see if I can get around to actually finishing my data.bin generator that I was working on. It's not cancelled or a cocktease or anything, I've just had to shelve it and prioritize other things before it. I do intend to release it sometime once I finish it and clean up the code!

we still dream of 48mb+ roms

 

[ootnes2]

Could anyone provide me with the extracted/dumped ROM for EarthBound (E)?
I am looking for it for research purposes, mainly comparisons between Mother 2 and EarthBound and all their released versions (3DS VC, SNES, SFC, Wii U VC, etc).

Someone could PM with the dump, please?

Did you come to any conclusions about the different versions of Earthbound? I believe that the snes and 3ds vc versions are the same.

Yeah, that's one of my to-dos for this month - to finish the SNES data.bin generator. I've been unpacking the past few days, but I'll try to allot myself time to try finishing this. Out of curiosity, are there any more finds with respect to different chips and whatnot that are supported?

no luck atm + no new nintendo releases

Apparently the ROMs seem to be the same, for both Wii U and 3DS.

The changes however seem to be stored within the RPX/code.bin files for the Wii U and 3DS respectively .
You see, both of those files include patches to the original ROM where they overwrite certain portions of text for the game.
So the ROM is intact, but when you run the game certain patches are applied.

Unless we find a way to dump the full ROM from RAM with the 3DS or Wii U, we won't be able to tell the exact differences between the two versions.

I notice that RyanHoe from that iso site is a bit managed to implement games with hi-res fonts perfectly (Rudra no Hihou, Secret of mana 2/3, Romancing Saga 3, etc..).

He did it by changing the internal snes rom header's region code, and padding it to be 6mb+

Have you looked at restoring sound to the rom dump? Vcromclaim seems to do it, but the resulting file has a different checksum than the rom floating around the net.

Also, doesn't tcpgecko dump from memory?

Restoring the sound?
You mean that thing about the VC ROMs that sometimes handle the sound externally with SPC?
I haven't tried looking at it too much to be honest, I simply looked at the main script of the dumped ROMs and that was it.

TCPGecko does dump from memory?
sadly, I don't have a PC to really rely upon to do that sort of thing.
If someone could do that for the official EB VC on my behalf, I'd be eternally grateful!

I think that's what the tools tab in Gecko dotNet does. Haven't you been working with someone on modifying memory of the snes emulator? It appears that the rom in memory is only a few bytes difference, what else would be searched to find the patched script?

Yeah actually the ROM in memory shouldn't be too different from the SNES one.
Do you by any chance have the memory dump for EarthBound?

I haven't worked with anyone to be honest.
And I can't do it because TCPgecko requires a PC to setup as a server for the data right?
I don't have a PC to do such feat. xD

 

[ootnes2]

Basically you dump parts as it is running, but you need something to search for. So far, the rom, the pcm file and the save file all appear to be in memory, any idea of what to search for to get the patch file?

The patch file wouldn't be found like that.
In the Wii U VC, the patches are made via ARM inside the RPX file called earth.rpx.
I would suggest getting the ROM dump from RAM via TCP Gecko and then comparing it with the original SNES ROM.
If you want to get a patch file, I'd recommend sending me the RAM dumped ROM. :v

Its ok, I was mostly just concerned with the sound piece. From what I can tell the rom dump is almost identical between the version in ram and the version from the converted rpx, which suggests that the VC is not patching the rom first, but is instead applying the patch some other way.
