We should compile a list of games this method works on, clearly it doesn't work on just any title. Obviously first game to add is SMO to the list.
So I guess I'll start then
Working titles:
  • Super Mario Oddysey
  • Fallout Shelter
  • Xenoblade 2
  • Fortnite (?)
  • Pokemon Quest

I can't get my game to extract properly. I'm using an xci and every time I use hactool to extract the nca it says section 0 and section 1 are corrupted. Any help?

Can you help me whit the commands for extract de romfs.bin and exesfs please
open a command prompt in hactool folder, place the file in the folder too (.nca, extracted from the .xci)
extract .xci: hactool.exe -t xci -x --outdir="your directory"
to extract romfs and exefs: hactool.exe -t nca -x --romfs=romfs.bin --exefsdir=exefs --keys=keys.txt file.nca

Switch backup loading is here: [prebreak]1[/prebreak]

1) Get a title id of any game you have installed from http://switchbrew.org/index.php?title=Title_list/Games (this is your target titleid)
2) Create a directory on SD : sd:/atmosphere/titles/*target_titleid*
3) use hactool to extract the romfs.bin and exefs files from your main nca from the game you want to run instead of your target (its in secure from XCI - the biggest one)
4) put romfs.bin in sd:/atmosphere/titles/*target_titleid*/romfs.bin, exefs files into sd:/atmosphere/titles/*target_titleid*/exefs/
5) Edit titleid in main.npdm (in exefs) to contain target title id (this might help http://switchbrew.org/index.php?title=NPDM)
6) run a fs_mitm containing CFW release, run your target app (https://gbatemp.net/threads/how-to-get-layeredfs-working.507460/)

Note that saves don't work for me atm, you should wait for mememenu/similar.
Minecraft works, others not tested.

How do I do step 3? What? When I run Hactool it closes instantly. I don't understand it.

    ooowwww a new way for me to beat NFS 510 :D @SylverReZ

  • SylverReZ @ SylverReZ:
    @AncientBoi, Yeah, believe you can do PSP games as well. But a Pi5 is much powerful in comparison.
    +2
  • Psionic Roshambo @ Psionic Roshambo:
    Not sure about other models of Pi4 but the Pi 4 B with 8GBs OCed to 2Ghz handles PSP really great except like 1 game I found and it is playable it just looks bad lol Motor Storm Arctic something or other.
  • Psionic Roshambo @ Psionic Roshambo:
    Other games I can have turned up to like 2X and all kinds of enhancements, Motorstorm hmmm nope 1X and no enhancements lol
  • Veho @ Veho:

  • Psionic Roshambo @ Psionic Roshambo:
    I will admit that one does seem more interesting than the usual Ambernic ones, and I already liked those.
  • Veho @ Veho:
    I dread the price point.

  • Veho @ Veho:
    This looks like one of their premium models, so... $150 :glare:
    +1
  • Psionic Roshambo @ Psionic Roshambo:
    To me that seems reasonable.
  • Psionic Roshambo @ Psionic Roshambo:
    I mean since basically all the games are errmmm free lol
  • Veho @ Veho:
    I mean yeah sure but the specs are the same as a $50 model, it's just those pesky "quality of life" things driving up the price, like an actually working speaker, or buttons that don't melt, and stuff like that.

  • Psionic Roshambo @ Psionic Roshambo:
    I think all in my Pi 4 was well north of 200 bucks 150ish for the Pi 4 the case the fancy cooler, then like 70 for the 500GB MicroSD then like 70 for the Xbox controller. But honestly it's a nice set up I really enjoy and to me was worth every penny. (even bought more controllers for 2 or 4 player games.) hmmm have never played any 2 player games yet :(
  • Veho @ Veho:
    Yeah that's what I hate about the RPi, it's supposedly $30 or something but it takes an additional $200 of accessories to actually turn it into a working something.
  • Psionic Roshambo @ Psionic Roshambo:
    yes that's the expensive part lol
  • Veho @ Veho:
    I mean sure it's flexible and stuff but so is uremum but it's fiddly.
  • Psionic Roshambo @ Psionic Roshambo:
    Yeah a lot of it I consider a hobby, using Batocera I am constantly adjusting the collection adding and removing stuff, scraping the artwork. Haven't even started on some music for the theme... Also way down the road I am considering attempting to do a WiiFlow knock off lol
  • Veho @ Veho:
    I want everything served on a plate plz ktnx, "work" is too much work for me.
  • Veho @ Veho:
    Hmm, with that in mind, maybe a complete out-the-box solution with all the games collected, pacthed and optimized for me would be worth $150 :unsure:
  • Psionic Roshambo @ Psionic Roshambo:
    Yeah it's all choice and that's a good thing :)
