Homebrew TWL Slot-1 Launcher (First custom DSiWare app!)

Yes. But did you check to see if you are using latest build of rxTools or a CFW with a custom TWL_FIRM installed first? It may be failing on the modified SRL. You have to make sure TWL_FIRM has sig checks patched out before knowing if your card doesn't work on 3DS or not. I've seen other users confirm that R4i-SDHC works via this launcher, so sounds like you're not doing something right.
Well... I've downloaded (and used, and yep it remade the data suite installation process) the build from this page : https://www.reddit.com/r/3dshacks/comments/453c9w/twl_firm_patches_ʖ_o3ds_only_atm/czuubl5
It didn't work, so I've downloaded the elf file on the same page and removed the data folder. Didn't work.

Normal SRLs have to be installed to both. But it sounds like my SRL doesn't need to be. CTR mode is probably reading the TID and passing that along to TWL_FIRM on reboot. Since CTR mode has emunand patch, it's able to read it from TWLN on emunand. I guess the SRL isn't used at all once TWL_FIRM boots because it immediately launches Slot-1. Which is cool. That means you won't need to have this on sysnand! :D

  • Tried using a R4iGold.cc card that works on my DSi 1.4U. Doesn't work on vanilla 3DS firmware.
  • Tried installing DSCardWhitelist v0 and TWLFirm 4.0-7 since that seems to be the firmware where my R4 got blocked.
  • Whitelist installs, TWLFirm does not. Card still won't load.
  • Installed TWLauncher to both sysNAND (9.2U) and emuNAND (RX-E 10.5U)
  • Doesn't load either.
  • I can not install a newer clean TWLFirm because FBI/DevMenu says it's invalid.
Welp.
Is there some way to format TWL NAND and reinstall everything again? Could System Format fix it?

DSiGold has been confirmed to work through the Launcher (and maybe without it. Just the new patches in TWL_FIRM may allow it to work) You may have not installed a modifed TWL_FIRM with the new patches or using latest rxTools. If that's the case, my launcher won't boot. So be sure to fix that before testing it. ;)

Ok I have an o3ds xl using RxTools, what should I do if I want to run the ds flashcart on my emunand? I have a m3ds real, so I have no clue if it will work with this, but is worth a try. I am asking because I don't want to mess my 3ds.

That's something I've been wondering for a while too.

Would it be possible to force DS games into a widescreen mode? Sure, it'll loot stretched, but I really hate the black bars besides the game :P
because i hate the screen little in dqmj games

Thanks for the explanation so there's nothing odd about my n3DS :)

Try to install the patched TWL_FIRM with BigBlueMenu or FBI destination NAND!

There are a way for force fullscreen on dstwo?

Don't think that's possible, but would be nice if we can get borders like the GBA player on Gamecube.

Okay so I've been trying to make this work on my old (and horribly fake of a fake) DSTTi Clone which was called R4i SDHC Dual Core white. The kernel of it can be downloaded from r4isdhc.hk which has been down for 3-4 years so I have no way of getting data for it. I managed to download RetroGameFan's collection of cart updates for fakes and I got it to work by renaming the ".dat" of a certain clone into a "iLL.iL". It worked on my old ds, but on the 3ds it wouldn't load. After a lot of fiddling, I managed to get this working and it made my pirate heart jump for joy! So I'd like to share some that I did to make this work:

1. The DS Cart should NOT autoboot from a DS. Meaning your card will not work if it autoboots. It must have a banner that you can press on the DS lite and use the cart from there. I have an old R4 that autoboots to moonshell and it won't work on the TWL Launcher. My fake card still needs to be pressed from the old DSlite homescreen to use the cart.
2. I updated my RxTools from 2.6 to 3.0 beta.
3. I replaced the elf file on my RxTools folder. Instructions: https://www.reddit.com/r/3dshacks/comments/453c9w/twl_firm_patches_ʖ_o3ds_only_atm/czuubl5

Dude can you send me the kernel? I have the exact same R4 but I get double white screen when I load it, how is the banner/icon in yours? mine has a white banner and a white icon

As long as it has a proper banner, it should work.
Is the exploit used for autobooting older dsflashcard using e specific adress to start code execution normaly? Because I think I read somewhere in the game header information you posted in the the other thread, that there is a field for a start execute address. If we set this address to code the execution address of older flashcards, do you think we could launch them.

It seems that R4i 3DS (www.r4ids.cn) is not working. I already have the dswhitelist.cia installed when I first set up CFW but it seems my 3ds doesnt detect it(no cartridge showing on 3ds). I tried updating to latest rxtools3.0b2, changed the elf file as @TuxSH mentioned but still the same scenario. So i tried installing @Apache Thunder app, then still the same result(I got an Nintendo error that says "hold down power button" or something). Am i missing something or is my card not supported?

maybe your card is broken, because it should show up, even if its not working.
