From the guide
If you already have arm9loaderhax set up to boot your emunand, you will need to remove it. This is because one of the needed tools, decrypt9, can only run from sysnand. Arm9loaderhax will prevent you from entering sysnand at all, so will need to be removed. I did this by restoring a vanilla 9.2 sysnand backup which I took from the console prior to installing arm9loaderhax.

Does this still apply? I can run decrypt9 just fine AuRei patched sysNand

Thanks a lot @stl25 . I will try it.

EDIT: It works well. But Decrypt9 is too bright imo :D. Would you mind to lower the brightness? Is that possible?

EDIT2: I figured out that we don't need "X_bl" to run software that need backlight. Is that true @stl25 ?


@jasonal21, here is a version that sets backlight to the original setting. @Ekaitz is the one to credit with not needing the _bl files to determine which payloads enable backlight.
Glad it works for you. @FIX94 made a great app to load payloads while allowing the user to determine which payloads enable backlight. Myself and @Ekaitz just edited the source to customize it to be more in line with folder structure of AuReiNand by the great @Aurora Wright. The limitation is if you have @FIX94 arm9loaderhax (in which backlight is set to zero) installed and use AuReiNand CFW with splash screens this will not allow you to see the splash screen the way I built this mod. If someone would like another version that will allow the splash screen to be viewed I can make another mod and post here. Take time to visit the AuReiNand and arm9select threads to give props to @Aurora Wright and @FIX94 for there awesome A9LH software.

Edit: Here are both versions (Splash and No Splash). Please note this mod assumes your default payload is AuReiNand named as AuReiNand.bin.

Pretty sure that only applied for when A9LH was first being used.
Sorry to keep bugging you about this, I'm in stage 3 for this guide that you previous posted. When I get to step 4 "Create an empty file on the SD card in the /rei folder called updatedsysnand" I can't get my 3ds to boot directly into updatedsysnand mode. I have ~/aurei/updatedsysnand.txt & ~/aurei/updatedsysnand.bin and it still default boots into emuNAND and holding L gets me into updated sysnand. Any ideas?

Delete updatedsysnand.bin, you don't need that.
Remove the .txt extension from the updatedsysnand file.

So I finished swapping them and everything is setup correctly, using a stopwatch I timed boot from power-button press to first sight of theme display and my time is 11.21 seconds. I did the same for emuNAND while holding L and it was 11.33 seconds. Are there any tips for making booting into sysNAND quicker? Not that it's not already fast compared to non-A9LH but I'm just curious.

Hope for improvements on CFWs.
AureiNAND recently got an update that apparently boots a second quicker than before.

I'm using arm9select (probably the fastest boot selector) and CakesFW autoboot, and it takes me only 9 seconds to boot into emuNAND.

Booting Decrypt9 takes like half a second.

Thanks guys.

The problem is I'm blind to code :P. But I'll try to learn to compile it :).
For now, I get better use arm9select mod.

Someone should make a an arm9 program similar to "ulaunchelf" for the PlayStation 2 (basically a file finder that launched apps).

    @Psionic Roshambo, people who cant download it can still play the game

    If your internet speeds are fast enough. Streaming 4k takes alot. I used to only have 20mb sec, and 4k struggled. Now I have 300mb sec and 4k plays fine.

    I think Game streaming should work like this.... Local Hardware able the run the game fine, game engine and common assets stored locally, all FMV and music and textures could be streaming

    Some temporary storage

    also @BigOnYa im making some progress on my gdevelop project, implemented various mechanics

    Or free government supplied high speed internet be nice also. Like Obama care. Xdqwerty that's cool, its time consuming but rewarding once done or playable, to see what you've made from scratch. Animations take forever, but worth it.

    @BigOnYa, although the bullets are a bit buggy

    Not to mention this would be a massive pain to pirate

    @BigOnYa,
    and the visual aspect of the game is quite crude (the sprite that looks best is that of the protagonist just because he is a stickman with sunglasses)

  • BigOnYa @ BigOnYa:
    There is a bullets behaviour you assign to your character, that makes the code easier, under "behaviours"
  • Xdqwerty @ Xdqwerty:
    i meant that when the character is pointing to the right, the bullets spawn where they should, but when he is on the right, they move to the right but the spawn point is incorrect
  • BigOnYa @ BigOnYa:
    Itch.io has lots of free assets also. Under the bullets behavior tab, there is a "rotate bullets" option, can try that. Or in the code can try
    - fire bullet Player.X(PlayerDirection)

    YEa gotta after a while, looking at code for long periods will bug your eyes.

  • BigOnYa @ BigOnYa:
    That's cool tho, I'm proud of you going back to it, not giving up. It is difficult at first to learn, but fun once you get the hang of it. I think I've watched every tutorial video there is, but I still struggle sometimes to get stuff to work right. But gotta keep trying dif things, and eventually you will get it right.
