Tutorial  Updated

Install NSP titles using devmenu and XCI / SXOS

Description:

Well as most of the methods is involving going to the eShop to get "Pokemon Quest" which is a concern for some people specially who want to stay offline for now until everything cleared up well using this quick way you don't have to

Requirements:
  • Switch with FW 5.1.0 (if you are on lower firmware use the @rajkosto method here for upgrading without burning fuses)
  • Flashback Game Backup in XCI format.
  • DevMenu Files (google it).
  • Optional: Hulu App NSP "to replace the Falshback as it is smaller size".
Steps:
  1. get "flashback" game xci backup or cartage
  2. make folder in root of memory card sxos/titles/{flashback title id}/{devmenu folders/files}

  3. get the devmenu "search for it on the internet" and backup a copy somewhere
  4. change the exefs/main.npdm hex values "for the devmenu" using HxD or any hex editor program

  5. Offset: 0x290 to 0000010000000001 0000C504000A0001 . and Offset: 0x460 to 0000C504000A0001

  6. save the file and copy the "sxos" folder and "flashback.xci" and the NSP files "you need to install to the root of the microSD card
  7. lunch SX OS and load the flashback game from the album

  8. open the game as it will lunch the dev menu

  9. choose install from sd card on top (if hanged or touch not responsive close the game and open again) you can install titles directly on system storage or memory card (as some games takes alot of space as xci but from shop is 75% smaller like "SteamWorld Dig 2"

  10. the installed titles will show up after closing the flashback game.
  11. enjoy

flashback titleID is: 01000A0004C50000 and i might do a video as well


UPDATE:

Hulu App
"NSP" can be installed by the devmenu for on 1st launch and used to replace "flashback" afterwards to reduce space on memory card or to be able to play the flashback game;) you still need the correct files for the devMenu modified for Hulu though (Tested with correct files thanks @willhack )

Hulu titleID is: 0100a66003384000

After installed sonic mania .nsp through devmenu on the latest FW 5.1.0 (SX 1.3) it says that it need access to eshop to redownloading the software what should i do ?

Try installing all the DLC/update NSP's for it until it works

If i am not mistaken there is about 2-3 extra NSP update files for Sonic Mania. Try installing those it should update the version of the game.

I use Hulu. Doesn't take much memory. Installed on the Nswitch so I can switch SD cards. If you don't have Hulu installed then you're still going to need this method to install Hulu nsp
Good idea but not so good!

Edit: you have to install Hulu as an nsp first for the DevMenu to work that beats the objective of staying of the radar detection!

Can anyone develop a smaller .xci as a donor maybe the op @ksamj202 can come up with a better solution smaller in size donor the better! Surely there must be a smaller .xci that can be used? agreed if you trim flashback it’s small but something even smaller trimmed out would be better.

Can anyone please tell me how do I get the ID for lines 290 & 460 (.main file) using hxeditior if I wanted to use a different xci donor a smaller one like steamworld dig 2 for example? Instead of flashback.

Thanks I know that ID title site but for example he’s used flashback in the op but the ID of the game doesn’t match the ID of lines 290 & 460 in the exefs/.main.. file using hexeditior he tells you to paste in so how do I get the ID lines for the donor title, if you know give me an example of steamworld dig 2. Or are you saying you just copy and paste the title ID to lines 290 & 460 for the xci to work with the DevMenu?

flashback titleid : 01000A0004C50000 revere it 00 00 C5 04 00 0A 00 01
goto 290 & 460 and overwrite it with 00 00 C5 04 00 0A 00 01 (look at the pic)

Thats not corrrect it hasn't reversed the whole ID:

Title ID of Flashback is: 01 00 0A 00 04 C5 00 00

Reversed Flashback would be: 00 00 C5 04 00 0A 00 01

OP's Flashback title ID is: 00 00 C5 04 00 0A 00 01 (which is not reversed backwards!

OP "flashback titleID is: 01000A0004C50000"
you already said Reversed Flashback would be: 00 00 C5 04 00 0A 00 01 which is exactly the same as OP's
look at step 5.
Offset: 0x290 to 0000010000000001 0000C504000A0001 . and Offset: 0x460 to 0000C504000A0001
