In that case:

Cool.

Huzzah. KPN sucks rooster, get Versatel or something.

Having everything completely random might turn out crap.

Know that for next time then. At least we have a theme now.

Background:

Meant to be a crack in the space-time continum. Don't think I pulled it off
Might edit after snader does tiles. Might not.

looks like a Grateful Dead skull

hey what sizes are the tiles supposed to be?

gba tiles are 8x8 or 16x16 if i remember correctly.

Ok since noone seems to notice me on the other posts at least I will use my programming essence to drive something here :D.

On GBA you have to make a difference among 2 kinds of graphical objects.

Sprites and Tiles.

Gba has 4 different layers for background + 1 backdrop layer (That is what's shown on the very back and is plain color)

The tiles for the background are 8x8 pixels wide.

All your sprites are made up of tiles as well but for Sprites you can choose different configurations SQUARE, HorizontalRECT , VerticalRECT. of course you can figure out what this means, dimension go from 8 to 64 in powers of 2

8,16,32,64 for square ones.
8x16,8x32,16x32,32x64 for V rects
16x8,32x8,32x16,64x32 for H rects

Thos are almost all the formats you can use. For larger ones you will need meta-tiles. Those mean the programmer will have to give you the ability to split your larger one into tiles, and he will move them accordingly.

For example a 128x128 sprite could be made up of 4 64x64 ones somehow but they are not handled natively via hardware like the other ones are.

There are 128x128 sprites those are handheld natively, but they are Zoomed sprites from 64x64 ones and can reach to a maximum of 2X resizing. But they use the same graphics of the 64x64 and apply a common magnification algorithm.

Sprites can be Roto/translated/flipped Vertically and Horizontally via hardware, so you can save up some work and memory.

Tiles have different color formats, 16 colors and 256 colors. Up to 16 16 colors palette can be used or a 256 colors one.
There are 2 different palettes sets one for Background tiles, and one for sprites (what I wrote above holds for both of them).
Total VideoRAM is 96KB of which on 32KB for sprites, and 64 for tiles. In bitmap modes they drop to 16KB for sprites and 80KB for background.

On each palette the first color is a transparent one. :)

I wrote so many tutorials and games for nintendo handhelds I think I will have nightmares with this specs even when I'll be on the grave :).

eheh

Hope this helps a little and/or clarifies... ask if need some more ;).

Cheers.

Crash!
Dude... I have downloaded some GBA SDK's and plucked and pulled around with them... Problem is, I don't know ANYONE who codes for the GBA... Any chance you would be willing to give me some tips? Or could point me to the best tutorials you know of? I don't wanna get HARDCORE into yet? I don't have a flashcard or anything yet... But I am interested in it for sure...

Nice little graphics tute man...

is this still going on?
