Hacking Auto Injectuwad Injector v1

[megabug7]

Ok it's plain to see from the injection list that using Donkey Kong Country 2 has the highest chances of success even if the romsize is 32 megabit and injected rom is smaller.

What I'm trying to understand is why if using a larger size host rom as your planned injection rom, does the result produce the same results as using a same size host rom.

ie.
Tried Bahamut Lagoon with DKC2 - fails
Tried Bahamut Lagoon with Super Metroid same size as BL - fails with exactly the same symptoms as DKC2

Also why do some work and others don't?
What are the differences in the roms (aside from a special chip which is obvious) that are of the same size yet fail to run?
ie. Secret of Mana 3 32mb - Theoretically should work on DKC2.

Or am I missing something?

Yay, technical questions! The wads are the same size because we're placing the smaller ROM over the larger ROM in the .app file (essentially), so there will be some of the larger ROM hanging off the end of the smaller ROM. Let's say we had the sentence, "Wii hacking is fun" and wanted to inject the phrase "DS ROM" into it. The result would be "DS ROMacking is fun". See how there is "left over" from the original sentence? Exact same way with the wads.

The reason why some games fail is because the size really has nothing to do with compatibility, its the way the ROM executes its code. Some games do fancy things with the SNES/N64/etc... memory or CPU that the VC emulator just doesn't know how to handle. Hope this helps a little.

Yes it does thanks

So what happens to the left over text in your sample? Do you remove it?

And from a 32mb host rom that has a 24mb rom injected what happens to the 8mb of data? Doesn't that corrupt the rom?

 

[creffca]

The left over text just stays, just like the left over ROM data. That's why the file size is staying the same. Technically you could say its corrupting the ROM, but that extra data is never looked out so it has no effect.

Ok Cool - thanks

I have 2 theories.

1: Only the games that WILL be released on virtual console will work.
2: Only games with the same kind of engine and data execution as the host wad will work.

Correct me if I am wrong.

probably so on game engines, especially n64, I'm guessing a 2d engine wouldn't work with a 3d game, but I doubt that games that will never be released don't work, we're just working all the kinks out so that we can figure out which ones are more compatible with eachother. I suspecct it has everything to do with the engine/emulator included with the VC rom, and not to do with a potential release.

Kirby's Dreamland 3 does not work due to SA-1 chipset, but its coming out soon, then im sure Super Mario RPG will work when injected into that.

I've been trying to remove the unusable wad that I installed, silly me, I seemed to have lost the one I made with SNP. Can I just use the regular non-injected SNP wad, or do I need to find/create a new version of the installed wad with the correct ticket? Thanks.

You can't just uninstall from the channel menu?

And for anyone who is interested, my next injectuwad release will have NES injection support.

It was my understanding, that to properly remove a game/ticket from the system, you had to use the uninstaller with the original file that you installed.

I did just try to unintall it using the original (unmodified) SNP wad file, didn't work. No matching ticket...

Well technically that is correct. Even if you uninstall from the channel menu it leaves the ticket name in memory. I believe you can see your installed tickets using the NAND dumper, but someone else will have to help you with it since I haven't used it yet.

 

[hemanthegreat]

Is there a way to delete tickets out of your nand? I'm guessing not since I haven't heard of one yet, but who knows.

I don't ever hook up to the VC store. I bought one game and decided it was a waste of money. I could always delete it without the installer. I'll just have to hold out for a way to get rid of the ticket I suppose.

using the wad uninstaller deletes every trace of a vc game wad

Just FYI Bahamut Lagoon is working perfectly injected into DKC2

yes but only if you have the file you installed with. I misplaced mine (though I swear the one in the recyling bin was the right one >.>) and have been unable to find a way around that.

 

[LoudMaximus]

if i already have an injected game(say smash bros into S&P) can i still install another version of the wad even though there will now be 2 S&P channels on the wii?

With hex job? I don't have the skills to modify a rom

If you can teach me I'd appreciate it.
Do you think that Terranigma will work with your method?
It has similar issues to Bahamut Lagoon (no music and crashes when trying to save)

I can't use a SNES emulator on the Wii cos of the PAL issue.

I was happy to get Treasure Hunter G to work
Disappointed Secret Of Mana 3, Terranigma and Bahamut Lagoon won't run

 

[Lexal]

The wadtool part doesn't work very good, but you can just do it manually.
Thumps up!

 

[Sir-Fritz]

Am i correct in thinking that i need twilight princess to install a wad file?

 

[megabug7]

Only way is without a modded machine is the twilight hack - so yes

 

[JJBro1]

ok i decrypted the wad, now what?
