Rockboy Color

[Quinjamincy]

I was wondering if there's a way to change the color palettes on Rockboy.  I know how to change to another one, but I want to know if you can add a custom one.  I play Pokemon Red on it alot and would like it in the same color as it really would be.

Sure, just edit the source code. Rockbox is open source, you just need some programming skills.

Sorry to sound like a noob, but how might I go about doing that?

The same color? Then you want a greyscale pallete, which Rockboy already has.

Options => Set Pallete => Gray (or Light Gray)

I think he means when using a Super Game Boy.

I don't think that'd be possible without the emulator supporting Super Game Boy, which Gnuboy does not (Rockboy is based on Gnuboy).

It is not compatible with Super Game Boy or Game Boy Advance.

Actually I meant the Gameboy Color, which has it in color too.

So basically you want older games to show up with the Game Boy Color's "default pallete"?

Have you looked at one of the two Multi-color palletes? The first one seems pretty similar to the "old colors" to me.

The gameboy color had special built-in palettes for a few key games, among them Pokemon Blue and Red, and I *believe* Metroid II. I think he's asking about the implementation of these special ones.

these were more colorful on a super game boy: http://content.answers.com/main/content/wp/en/f/f1/Bulbasaur_pokemon_red.png

I know, I had a Super Game Boy. Pokemon Yellow, Gold, and Silver were "tri mode" cartridges; they had greyscale, Super Game Boy, AND Game Boy Color programming.

Nostalgia aside, I'm not quite sure about the GBC "special palettes". The GBC box (or a GBC game box, maybe) did say that it would render older games with "4 to 10 colors" (whereas the old Game Boy used "4 shades of grey.")

Maybe you guys should look at Visual Boy Advance. (Just a thought; don't know if it's in C or even GLPed. )

VisualBoy Advance is GPL'ed.

I found all the special pallettes like metroid, but I didn't see on for Pokemon.

So make one.

How can I do that?

Set up a development environment: http://www.rockbox.org/twiki/bin/view/Main/DevelopmentGuide

Then look in /rockbox/apps/plugins/rockboy/.
In palette-presets.h, add a new block for your palette (colour codes look to be in the format 0xBBGGRR), and increment this count:

int palettes [17][4][4] = {

In menu.c, add a line for your new palette in here (in the same order as palette-presets.h):

Code: [Select]

    static const struct opt_items palette[]= {
        { "Brown (Default)", -1 },
        { "Gray", -1 },
        { "Light Gray", -1 },
        { "Multi-Color 1", -1 },
        { "Multi-Color 2", -1 },
        { "Adventure Island", -1 },
        { "Adventure Island 2", -1 },
        { "Balloon Kid", -1 },
        { "Batman", -1 },
        { "Batman: Return of Joker", -1 },
        { "Bionic Commando", -1 },
        { "Castlvania Adventure", -1 },
        { "Donkey Kong Land", -1 },
        { "Dr. Mario", -1 },
        { "Kirby", -1 },
        { "Metroid", -1 },
        { "Zelda", -1 },
    };

and finally, increment this number to match:

rb->set_option(items[6].desc, &options.pal, INT, palette, 17, NULL );
