Homebrew [Release] Custom ROP loader HTML

[Manito]

I have coded a simple universal VC loader HTML code where the user can specify the ROM name, and it seems it's working flawlessly :-)

<input type="text" value="romname.gbc" id="customvc" /> <input type="button" value="Accept" onclick="window.location='roploader.html?VC.dat&gbc/'+document.getElementById('customvc').value"/>

Cool!I'm gonna try this out!

With this you will need to type a ROM name each time you need to load it. While bookmark must be typed only once.

Yeah, but it's useful for doing quick tests :-)

The "romname.gbc" is on the WebServer? or is in the 3DS?

This is a simple shortcut that builds the needed URL for a specified ROM. So roms must be still placed in the SD.

If the rom I want to load isn't named rom.gbc, it won't load for me! It's not just with this HTML textbox version, even if I manually type it. I'm tying with Pokémon Yellow.

EDIT: It's yellow (for me) when it doesn't load. Thanks in advance!

It would be great if you make a code.bin to fix the MSET form gateway.
I cant start any ds software on a 9.5
Thanks.

If I put index.html on the server, will people who go there be able to boot code.bin from their SE Card?

Yes

 

[DarkFlare69]

Yes

Okay, and I thought all LoadCode.dat files were the same... I thought that simply loaded the codes. So why does it make a difference if it's longer than 768 if they're all the same, and how can it be longer than 768 if they're all the same?

It can't be longer than 768 bytes, at least with the currentvwebkut exploit implementation. I made it shorter because the actual payload data is padded to 768 bytes when loaded by JavaScript. The ROP gadgets is unique for each browser version.

what is working for you on 9.5? i'm curious

Loading code.bin, I'm guessing.

 

[AugustoKazt]

Loading code.bin, I'm guessing.

hmmm maybe, thanks for reply

 

[Retr0Capez]

Loading code.bin, I'm guessing.

Yes, Loading code.bin

 

[DarkFlare69]

Is it possible to load a code.bin from the server? How would I do that?

 

[duke_srg]

DarkFlare69 As I already set, ROP load is limited to 768 bytes, that is onply data that can be passed thru the exploit.

The LoadCode gadget have about 412 bytes of free contiguous space (well with magic 4-byte word inside). If you can make code of that or smaller size, then yes, it can be loaded with JavaScript part changes.

is it possible to make a LoadROP for 1.7455 ?
my browser is from 4.0.5-5 (not -7) so I can't use any exploits.
that would be great if homebrew could be launched with this version, not only Gateway exploit.

Theoretically yes, but it us much easier for you just to update to one of the supported versions.
