Hacking Using custom launcher.dat with Gateway Go

[st4rk]

St4rk, how do I modify the screen. From what I'm getting, that code only retrieves the screen, and I don't know how to modify/set the screen. *knows nothing about asm*

look ctrulib and examples/3dbrew

 

[shinyquagsire23]

What I have done:
*sniperoni*
Both have returned me to the home screen with the usual error message and Download Play still open. My firmware, which I feel probably doesn't matter, is 8.1.0-19U. Any clue what is going on?

Apparently I didn't actually upload the most up-to-date unlaunch.dat to my Github, so it crashed on 7.x-9.x 3DS's (and probably 6.x-7.x). Try giving it a go now.

I tried to make the helloworld from ctrulib, it resulted in 350kb file first, i unlinked some unimportant libraries and its still 150kb... its really hard to fit something which can display helloworld on the screen using 16kb

Ah, don't use the #include <3ds.h>, just copy the code necessary(just a hint), i didn't tried a hello world, but probably the font file is big.

What do I need to do to build a .bin, instead of the other files, if I'm using crtulib?

I honestly don't understand what is going on. I have moved both Launcher.dat and unlaunch.dat to my SDHC, put it in my handheld, turned on my handheld, put in a game, opened Download Play, and access both of the sites. I just get a crash, and nothing else. I grabbed the download from this link, as you said to redownload it. Is that the wrong place? If so, tell me. If you'd like, I can capture a video and upload it to show you what is happening.

Still can't figure it out...(as mentioned before, not good with compilers)

 

[Slushie3DS]

This is unbelievably frustrating.

Just going off the top of my head here, but since it seems you grabbed it from the right place:

• Make sure to go to go.plxhack.us for the unencrypted version
• Open Download Play and background it (important!)
• Clear cookies?
• Actually have a 3DS gamecard inserted (also important)

Can't think of much else that could be the issue. Had it tested on 9.x though and it works just fine, so just make sure you're actually doing the process correctly.

Wait... gp.plxhack.us? I was going to go.plxhack.us.

 

[shinyquagsire23]

Derp, go.plxhack.us, not gp. Finger slipped I guess.

I cleared cookies, history, went to go.plxhack.us, and still just a crash. I will upload a video later.

Was the link I posted earlier, to your github, the most recent upload?

 

[shutterbug2000]

Hmmm... Idea here. I've seen some launchers that load .bin files. Would it be possible to make a Launcher.dat for this, to load a .bin file?

Yeah, that's the most recent upload. I might try and get a hold of a 9.4 3DS somehow and test it that way, no idea why it might be crashing though unless I accidentally modified something in the actual webpage payload itself.

Same thing is happening. I wonder if it is just the game, or if it is my 2DS, or my firmware, or what. It's very strange. I have filmed a video, and I will upload it once the weather here calms.

This is happening with the normal Gateway/encrypted version as well?

Yes, I have taken the Launcher.dat file from the download link in the ReadMe, tested it on go.gateway-3ds.com; I've taken the Launcher.dat from your hub, tested it on go.gateway-3ds.com; I've taken the unlaunch.dat from your hub, tested it on go.plxhack.us. They all resulted in the usual crash, but no magical black screen. I wish I could test if it is just my cartridge, but I have no other games at my disposal. I don't really know why it would be my cartridge, other than that it is made for the region my 2DS is made for, and that it was around when firmware was below 4.5. The worst of luck right now, is all. I appreciate the help.

Wow I looked away for a while and look what happened, holy shit! This is exciting.

Hm, if it crashes with smea's Launcher.dat I'd maybe ask around on #3dsdev, I'm sure someone might be able to help there. Although I haven't heard any reports on if this has worked successfully on a 2DS yet though.
