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

[TUWieZ]

I believe I'll manage to make a bookmark-based ROM selection way much sooner than any ROP/ARM11 based GUI will be made

True, I was just making a suggestion though lol. I can't lie I'm no programmer of any sort and I don't know the limitations here, but a file list of a specified sd directory doesn't seem impossible if this tool can load a .gbc from sd with a specified name. And the progress in just the past 3 days by kazo and shutterbug has been phenomenal. I don't doubt their ability

Anyway like I said I'm no programmer so its time to embarrass myself and share what I believe I was referring to earlier
https://github.com/Drenn1/GameYob/blob/master/platform/common/filechooser.cpp
I know, its probably a lot more complex than stealing some code from drenn's source

Just realized KazoWAR's version also works with GB console! Though still have issues with over 32kb, i.e. banked roms, in Kid Icarus VC
Managed to make stable one rom selection with URL parameter, follow there for usage details http://gbatemp.net/threads/release-custom-rop-loader-html.379531/
Now, the idea of rom selection:
- VC.dat is based on LoadCode with added additional write of a rom filename (which is substituted from URL parameter while loaded in 3DS browser) to a VC.rom file
- VC.bin is the same KazoWAR's code.bin with added rom filename read from file VC.rom

Can't solve the rom filelength issue, i.e. adding more zero pading after FileNameRom allows to set longer filename, it is written to VC.rom, but in this case ROM is just not loaded.

Spoiler: VC.S code

duke_srg Haha I've been waiting for this eheheheh >: )... Now that I can bother you again, I have a question for you. The updated VC.dat, it shows max file name WITH extension = 8, so does that confirm that "pkmnylw.gbc" is too long? Also, is it an updated version? 'cause even when I tried dkc.gbc (for Donkey Kong Country GBC ver), it still didn't work.

Let me know, I'm off to see a client today so I'll be pretty busy! Thanks in advance, friend-o. .

EDIT:

Changed all the names of the games to 3 letters .gbc, they work!! Even Pokemon Silver worked for me. Thanks a lot, buddy!! I used 2 different URL's (bookmarks), and both games loaded fine. Thank you so much. . This is awesome!!!

 

[duke_srg]

SinkyChan17 4 letter for name should work too. 8 letter total including a dot, like pkmn.gbc or pkmny.gb
I hope someone experienced in 3DS homebrew will fix the issue, because I don't see any limitation on ROP side

still i dont get this to work help please

What is VC app you're trying with?

i tried different things sml1 sml2 super mario deluxe Zelda dx different other zeldas

Super Mario Land Deluxe and Zelda DX are working for sure, reqd once more carefully how to make it work.

 

[ZOOT]

i did everything posted not working :-(

 

[duke_srg]

Just describe what you did

 

[ZOOT]

Just describe what you did

1. Put all the files in the zip on sd card

2. Open up a 3ds vc, but(important), mash the home button to return to Home menu ASAP.

3. Load website http://dukesrg.no-ip.org/3ds/rop/?LoadCode.dat on the 3ds.
(http://loadcode.projectpokemon.org/ for 9.3/9.4 users)
(NVM this. I messed up )

4. Return to vc, hit reset on bottom screen(also important!)

5. Done!

 

[ZOOT]

on 1 3ds nothing happens
on other i see pixelated screen nothing more\

Or I got it, just get code.bin from here http://gbatemp.net/threads/injectin...e-web-browser-sure.379760/page-9#post-5307660 or if you're going to use several roms, follow there http://gbatemp.net/threads/release-custom-rop-loader-html.379531/

thnx also tried dthat already


i think i have bad luck

[AntnioMoura]

It have annyway to put lots of roms on the SD Card to use the one i want?
I am in 9.4

 

[AntnioMoura]

Sorry the double post but I was playing Wario Land 2 on my 3DS(Injected on Pokémon TGC) and it saves. So i reboot my console, execute the exploit...and my save game was there!
It's that possible?

 

[duke_srg]

AntnioMoura look my post above, there is a way to have several Roms and open by browser bookmarks. The save game persists in case it uses less save memory than the original VC ROM.

Given that's the instruction from the original post, what did you name the rom? iirc at first it used rom.nes but if you're using kazo's it needs to be rom.gbc

Also clearing browser cache/history is important. Let us know what color the bottom screen changes to upon browser crash too
Red-Rom not found (Could be named incorrectly)
Yellow-Rom too big for VC
Green-Should be good

 

[AntnioMoura]

duke_srg this one right? http://gbatemp.net/threads/release-custom-rop-loader-html.379531/


But i don't understand what should i do can you explain in "dumb" language?
