Homebrew Injecting roms into VC? With only the web browser? Sure.

[shutterbug2000]

If your looking to name the VC Inject exploit you are doing, I came up with a few

ShutterSmash
VCject
ShutterJect
Shutter Console

Niceeeee !

 

[Shubshub]

Niceeeee !

Now if only you could make GBA games get injected and run Considering with the Ambassador Program they were run natively on the system as far as I am aware

Ok. So, I've figured out my problem:

        for(j = offset; j < (offset + 0x100000); j += 0x10000){
                IFile_Read(this, read_len, buf, 0x10000);
                GSPGPU_FlushDataCache(buf, 0x10000);
                GX_SetTextureCopy(buf, j, 0x10000, 0, 0, 0, 0, 8);
                GSPGPU_FlushDataCache(j, 0x10000);
                //flashes mostly black screen on the bottom screen for a few frames, this is so i know the program is running and not frozen
                GSPGPU_FlushDataCache(0x18000000, 0x00038400);
                GX_SetTextureCopy(0x18000000, 0x1F48F000, 0x00038400, 0, 0, 0, 0, 8);
                svcSleepThread(0x400000LL);
                GSPGPU_FlushDataCache(0x18000000, 0x00038400);
                GX_SetTextureCopy(0x18000000, 0x1F4C7800, 0x00038400, 0, 0, 0, 0, 8);
                svcSleepThread(0x400000LL);
                }
                IFile_Open(this, L"dmc:/memdump2.lol", 0x6);
                IFile_Write(this, written, buf, 0x10000);
                GSPGPU_FlushDataCache(0x18000000, 0x00038400);
                GX_SetTextureCopy(0x18000000, 0x1F48F000, 0x00038400, 0, 0, 0, 0, 8);
                svcSleepThread(0x400000LL);
                GSPGPU_FlushDataCache(0x18000000, 0x00038400);
                GX_SetTextureCopy(0x18000000, 0x1F4C7800, 0x00038400, 0, 0, 0, 0, 8);
                svcSleepThread(0x400000LL);
                }

This code seems to be completely overwriting the buffer! So, according to a RAM dump, only the last 0x10000 bytes are there... the rest is just 0x00.

So you've just about got it to work then?

Kinda, yeah.

 

[Shubshub]

Kinda, yeah.

Well if you need testers I'll be happy to test I've only got Super Mario Bros Deluxe VC, Which is 1MB If I am correct

Once a get a "beta" build I'll post it on the front post and announcement post.

Me too. I can also test it!

 

[Plstic]

I've got a nand mod so I'm ready to test what ever.

 

[shutterbug2000]

Have a plan here. If this works, I'll have a beta VERY soon.

 

[shutterbug2000]

I've got a nand mod so I'm ready to test what ever.

Also, there's no need for a NAND mod for this . It only injects into ram, nothing should ever touch NAND at all(besides, vc is userland right? So no nand interaction at all, correct?)

[blopa]

kinda of topic, and I'm sorry about that, but is it possible to inject only a .sav data into the VC game? Like a save file from my emulator on PC?

 

[shutterbug2000]

Quick question: Could I, instead of using *buf, use another int *?

 

[shutterbug2000]

Ok, the next version is ready! This time, it has support for up to 512kb roms, and STILL no gbc support ... It's in the works

Here's the NEW google forms

Bad luck, this version gives a black screen after restoring to a VC with Paragon5 Music Cart at least.

BTW, is it possible to scan Web browser memory for the URL, It may be the easiest way to specify a rom filename.

2ALL: guys, please check my html exploit on fw 9.3/9.4

I can't really test anything till GBC Injection is working Cause I don't have any GB VC Games

 

[SelfDEstruction]

I got something interesting after injecting Kirby's Dream Land 2 into Super Mario Land 2.. my 3DS beeps every 5 seconds when playing the rom

 

[Hiccup]

Could this, in theory, be used to inject custom stuff into physical games (e.g. custom levels in nsmb2 cartridge)? i.e. a bit like riivolution.

I Don't believe so but it doesnt rule out the possibility of doing SOMETHING with the browser exploit.
