Homebrew RELEASE NSPatch - Patch NSP Files to their actual needed FW version

[rrocha]

Or better yet, look for the xml in the header, and directly jump to its offset in the filedata.

Good suggestion. Went back to hactool, stole some of their code (as I don't need to the full blow app) and used the offset to speed things up. It's almost instant now.
Source code includes a note stating where hactool code starts and ends, so credits are due.

@adrifcastr I've created a c++ patcher (no need to unpack and repack). You can either compile it and distribute it together with your app or port the code to your favorite language.
Further optimizations would be to do a reverse search (as the XMLs appear to be packed towards the end) but it's fast enough form me as it is. Furthermore, it's open-source so people can grab it and improve it if they want.

Anyway to get your patcher already compiled? I haven’t got a clue how to do it...thanks!

setup mingw or vs builtools, or wait for nspatch do include it as dll

Check the original post. It has very crude instructions on how to build assuming you know your way around a compilation environment. It also has a pre-compiled version for x64 MacOS
If someone wants to build it for Windows or *nix platforms, it should be trivial.

Does anyone know if this patch method works for updates and DLC requiring an update when I'm on 4.1? I get that tinfoil may not install updates or DLC, but I'm using Devmenu which works with any NSP file.

Read op. NSPatch can merge base games and Updates using hactool

I don't understand this tool. I tried this with Donkey Kong and Captain Toad, which both require afaik FW4. Than, after using this tool, it tells me, they are now playable on firmware 5.0.0? So does the games require FW5? Or how can i patch them to work with FW4?

I just used this as well and it increases the playable fw instead of reducing the playable fw
How do we make it reduce the fw exactly

Guys I'm on 4.0.1 and even if tell that's playable on 5.0 work on my firmware. I've tried Crash Bandicoot... Don't worry about the message... it works... just to be sure to be in the same page I'm using an old version of tinfoil that seem to be good... With the newer version, at least for me, wasn't working fine...

actually the keygen detection on 2.0 is fine as it is so it should work fine and accurate. also patching would be 90% faster if I wasn't to dumb to arbitrary read and write to binary files, but I'm working on it.

 

[adrifcastr]

edit: don't use 2.1 myself being a dumbass forgot that I commented out the line that starts the patching. will be fixed, the next major release won't require extracting/repacking either

 

[adrifcastr]

Tinfoil now supports ignoring the reqsysver so I'll get this locked up, Thanks though to those who used NSPatch!
