Hacking Wii U Hacking & Homebrew Discussion

I thought the bug was patched in 5.4?

different bug that was patched in 5.2

Nah, that's different, you need to use Dumpiine to get it from your console and then you can disassemble it (or try digging through memory to try to find it, I wouldn't be the one to ask how to locate it). You might be able to patch the one RPL that handles TV output

I have a RPX from Wii Fit U, it is Step.rpx, it is about 8MB, but it doesn't seem to have a RPL (I downloaded the WUD from internet, then I extracted the game and got all the content,it works with Loadiine) Could be possible that the Step.rpx controls the internal game resolution? I don't have any idea how to disassemble, is there any tool?

First you need IDA pro, and the .RPX plugin.
But I can be wrong, I have little to no experience for disasm.

Ah, I see. But Naehwart said that <5.2.0 was "easy" IOSU, so doesn't that imply that there's a bug that would require more work that still exists?...

RPLs are from OSv11 (7th down), basically all the dynamically linked libraries you can call, Cafiine patches FS functions in coreinit so theoretically you can patch anything that's loaded. Also, yes, games have to set their own resolution and framerate, that's why Mario Kart 8 and Splatoon are 720p60 whereas others can handle 1080p

Yeah, I can try to dig up the topic.

 

[Imparasite]

so in near future only from 5.2.0 US/EUR/JAP below can benefit the exploits? omg ive recently updated my firmware, online gaming is very addictive this days lol

Um, I see, so if I want to patch a game RPX I need Cafiine to load the custom one, right?. Well I found this about IDA RPX Plugin, will this help me?

Also, sorry if it really stupid, but I need to dump form my console/download with nusgrabber OSv11 to see the RPLs? .

If you find a way to do so, it would be good to documents it or ake a tutorial to hopefully be able to apply the custom resolution to VC titles too.

Nah, you need to use TCPGecko to find the address it's at and then patch it at launch. Also yes, that's what I've been using for a while. You can use UWizard to download the title

00050010-10004009 - OSv9
00050010-1000400A - OSv11

Does this actually make sense to anyone? (Hint: A is hex for 10)

That's neat. A is 11 in hex

Edit, wait, something is wrong in what I just posted xD Should be B

Still, I can't even dissamble the Wii Fit U RPX :/ , before trying to patch anything with TCPGecko I should open the game RPX, but still don't know how to do it exactly .

You can decompress it to .elf and open it with (TCP)Gecko dNET (go to the disassembler and click open dump and select the .elf).
If the .rpx is responsible for the game's resolution I don't have any idea how to find the asm code of it.

Mario Kart 8 and Splatoon are 720p60

How do I know what resolution each game supports?

Again, I wouldn't be the person to ask. These are from reports and news sites.

Damn... I thought it would be easier to change a game resolution , only I can suggest you for games resolution is seeing Digital Foundry reports, you can find the resolution and frame rate from many games, however there are ones that doesn't appear there.

lolyea 0x0A is 10.

Looks like they use version numbers which Microsoft left out for Windows.

Maybe to avoid mistakes with OSv1.0 and OSv10

 

[endoverend]

but there is no OSv1.0...

That is precisely what happens when you let the nomenclature task to a trainee /s
