devkitPro

If you mean this Getting Started page, there are no instructions about compiling devkitPPC, only about installing. You should only be compiling devkitPPC if you plan on aiding in its development (that is, development of devkitPPC, not development of Wii/GC homebrew).

Am I right in assuming that a new variable named tmpfb is created? What is the purpose of the asterisk? What does xfb mean? What is the purpose of the [y+1]? What does the >>= symbol mean? I've never seen it in C/C++ Programs before... Yes, a new variable named tmpfb is created. The * indicates tha...

There are three kinds of sprites: 4bpp Tiled, 8bpp Tiled, and 16bpp bitmapped. 4bpp ones use the SPRITE_PALETTE (or SPRITE_PALETTE_SUB). The "palette" parameter picks which 16-color "row" to use in this 256-color palette. Use the grit options "-gt -gB4 -p" 8bpp ones use...

What grit options were you using previously. And what parameters did you use in oamInit?

VRAM_F_SPRITE_EXT_PALETTE is an enum, not an address. You probably want to use VRAM_F_EXT_SPR_PALETTE. /* Unlock vram (cannot write to vram while it is mapped as a palette). */ vramSetBankF(VRAM_F_LCD); /* Copy main_gfx palette into palette memory. */ dmaCopy(main_gfxPal, VRAM_F_EXT_SPR_PALETTE, mai...

Yes definitely the you have overflowed the stack. The sizeof(animation) is 21856 bytes (quite a bit higher than the 16KB limit). Change "animation a = new_anim();" to "animation *a = new animation();" or "animation *a = (animation*)malloc(sizeof(animation));" It appears...

Yes. Try a different emulator. Desmume is particularly good for testing homebrew

This works as expected for me. Maybe you can describe what is a "crash"?

swiCopy may be hanging if you give it an invalid pointer. I don't think dmaCopy will hang in some (if not all) circumstances.

I added up the graphics and calculated 33436 bytes. If you used SpriteMapping_1D_32, then you have gone out of bounds of sprite graphics index (max 32KB). If you are mapping 128KB of VRAM for objects (which it appears you have), then I would suggest switching to SpriteMapping_1D_128. Make sure to ch...
