The ultimate in GBC VC injection today!
​

Hello everyone. Today I'm releasing a Windows tool that will make the GBC injection process much easier and customizable. I'm introducing Ultimate GBC VC Injector for 3DS.

What does it do?:
It takes a Color Gameboy backup file and converts it to an installable CIA for your 3DS with CFW. It does all in a one single program.

Features:

• VC GBC injection into a CIA
• Easy made custom colored 3D banner
• Easy made custom text/footer banner
• Easy made custom ingame border injection
• Easy made whole process!

Requeriments: Microsoft .NET framework 4.5

Tutorial:
You'll just follow the steps in program. But just in case:

Tutorial + screenshots

Step 1:

Rom file selection

Open the program. You'll see this screen:


Press Open GBC File button. It'll prompt you to pick a .gbc file.


For this tutorial I'll pick the spanish edition of Pokémon Gold.

When you pick a rom you'll be able to go to Step 2 (icon and name).

Step 2:

VC game icon and name

This is the Step 2 main screen:


All the fields are explained in the info boxes, but let me know if something doesn't understand.

Complete the fields making the most legit as possible (if you want to). For example:


I used a title screen screenshot in it's original size as icon (the program will automatically stretch it).

When you complete all the fields you'll able to go to Step 3 (3d banner).

Step 3:

VC GBC 3D banners

This is the Step 3 main screen:


Note: The program will load some default values (based on those in Step 2), but you can anyway replace these default values with ohter ones.
Example: if you want the icon and 3D banner to have different images, then first complete Step 2 with the icon image that you want and then complete Step 3 with the banner image that you want. Otherwise if you are too lazy or you want the same standard as legit VC CIA, leave it as is.

For this example, I'll let the same image as the icon, but I'll change the banner color for a golden one. To do this, just press Change frame color button and pick a color.



There is a crappy preview of the banner color. The real one will be in 3D!

Also, I'll edit the bottom banner text, adding the release data (in spanish).
You can change the font type, size, and brightness. Also there's a preview of this text banner (ignore the red borders, they won't be there in the console).

Doing my changes for this example:


When you complete or modify all the fields you'll able to go to Step 4 (VC parameters).

Step 4:

VC parameters

This is the Step 4 main screen:

(ignore that info box, it's not actually very explanatory)
​

In this screen you can make the game full screen (as long as you launch the game without holding START or SELECT button).

I was experiencing with the ingame borders. You can select a few frame styles (discover them on your own ). You can now import a custom one (it's any 512x256 image).

For this example I don't want the full screen mod, but I'll pick a non-purple colored frame, picking a light blue color for the frame (because I want to and I can ). This is the result:


There's some things I didn't say, but I think they're self-explanatory (If not, let me know!).

Once we have everything ready, press Finish button.

That's it! The application will ask you where do you want to save the CIA file and It took some seconds to create it.
When the CIA is ready, the application will let you know it.



Then you can install the CIA in sdcard using any CIA manager (actually I use the new FBI).

TODO, petitions, etc: For now I'll just read this thread and make changes acording to the best for all. The code will be released much later; I'm planing to do a series of VC injectors... If a new version comes, I'll post here and I'll edit the OP.

+ Added: Now you can choose the message that we will see in the Home Menu when closing the game after suspending. Asked by @noctis90210.
+ Added: Native IPS patching. Now you can apply an IPS patch directly before making the CIA. Useful for use with GBA enhanced patches (just an example, any IPS patch will work).
+ Added: 6 new built-in VC borders: Pokémon Blue, Pokémon Red, Pokémon Gold, Pokémon Silver, Pokémon TCG and Kirby.
* Fixed the "Can not find a part of the path 'C:\Users\..\rom\vc1904.bin'" error that was present in 32 bit Operative Systems when using the New VC option. Reported by @darkalex004.

+ Added: Option to make an injection with the new Virtual Console (that one which has no savestates and supports Link Cable if you have the correct game patches for that). Thanks to @Traiver.
* Fixed: Override the imported icon.bin flags with another ones, so the game will show on the activity log, and the parental controls won't be a problem.

* Now if you make the .3ds version, the app will also make you the CIA version
