Homebrew NTR Launcher - Bring back that classic DS boot screen for your DS games!

[tdawg135]

I can finally give this a release thread. This is "NTR Launcher". A stripped down optimized version of NitroHax but without the cheat code system. This simply launches the game you have in slot-1. Patched dev launcher required. Be sure you have game inserted before you start it. EDIT: Patched dev launcher no longer required for to use NTR Launcher!

The alt build is included with the same release file as the main build.

nds folder should be at root of your 3DS SD card.

Wow, I'm definitely shocked! My old EDGE DS flashcard works! This is really cool, Thank you for this! The only problem I have is that I have to remove the card and then insert it on the DS splash screen in order for it to work.//

Have you tried toggling the reset slot option in the .ini file?

Holy Smokes, That did it! Thank you!//

NTR Launcher (as well as TWLoader, which uses it) seems to be unable to start System Flaw correctly. It shows an error saying the game is designed for DSi only. (I suspect DSi-enhanced titles will start in DS mode, though they won't have a visible error.)

EDIT: The bootloader code doesn't send command 0x3D nor does it load the arm9i/arm7i binaries. I'll see if I can hack something together tomorrow.

EDIT 2: ...and arm9i/arm7i is encrypted using AES-CTR. It's a known algorithm, but this is probably way too complicated for me to take on right now. :X

Thanks for this, I dug out my ancient R4-sdhc which, thankfully, still had fw on the website and it worked like a dream. Good job

 

[Risingdawn]

Quick question @Apache Thunder is there any way of using wi-fi functions on the r4 card and is there any benefits to twloader over this? Sorry to bother you with stupid questions.

@Risingdawn TWLoader is a frontend for NTR Launcher. It provides a GUI for adjusting NTR Launcher settings as well as specifying use of nds-bootstrap.

Ah brilliant, thank you for the reply I shall try that.

Hi, can anyone help find the correct files to run this card (http://i.imgur.com/yhRnWoY.jpg). I think its a clone because I grabbed the original wood r4 and its stuck on Loading... black screen.

Were you able to figure this out? I've tried a bunch of things and haven't been able to get this card to work, either with this launcher or TWLoader.

I can't run my EDGE cart (2.3 FW), what did you do in order to make it work? Running Luma 6.6 with A9LH, copied the nds folder to my 3ds root folder, installed (and tried) both builds to no avail. I also checked the "patch SVC/service/archive/ARM9 access" in Luma configuration. Got as far as the DS splash screen before it white screen'ed on me.

my ntr_launcher setting:

[NTRLAUNCHER]
DISABLEANIMATION = 0
NTRCLOCK = 1
ENABLESD = 1
RESETSLOT1 = 1

[NTRLAUNCHER_ALT]
DISABLEANIMATION = 0
NTRCLOCK = 1
ENABLESD = 1
TWLMODE = 1
RESETSLOT1 = 1

*edit: Got it to work one time, using the normal build. Tried to insert the flashcard after "insert cartridge to continue" prompt appeared (enabled RESETSLOT1 as you can see above, but I figured, what the hell), and it worked. loaded the rom and all, saves also working properly. Subsequent launch resulted in white screens again, sadly. It shouldn't be a physical / pin problem, tried to eject and boot the same card 10 times on my old DS Lite and it worked perfectly each time. any guess to what the problem is?

any news about ezflash Vi ? it would be the only one flashcard that dont work with nds-bootstrap?

Greetings

Set ENABLESD and TWLMODE to 0 and see if you have more luck.
If the card is inserted properly, it should appear on the home menu as a DS cartridge with a blank white banner.

TWLoader and forwarders, you mean?
nds-bootstrap only does ROM loading from SD Card.

You can look at the source code of TWLTool if you need an example to work on. Though in the mean time it would be nice to at least have TWL carts work in NTR mode. (the ones that aren't DSi Exclusive)

Thanks. It booted, although I still got white screen from time to time. I guess it's a phisical problem after all. Will try cleaning that cartridge with an isopropyl alcohol next.

Thanks, everything works perfectly on my O3DS and N3ds !! I can boot my games+R4
One thing, what's the difference between normal and alt build?
Thanks in advance
