devkitPro

OK I got it to load properly. The memory offsets were a little off when reading from the gfx pointer in dmaCopy(). I think maybe the grit in the DevKitPro toolchain packs the tiles differently than the one used by the guy who generated the example tiles using Pern Tools. So my code looks like this n...

OK I still can't get the bg to load properly. It looks like it's loading the image into a 256X512 space row by row, so it looks shredded into strips. My updated code looks like this: videoSetMode(MODE_0_2D); vramSetBankA(VRAM_A_MAIN_BG); int bg = bgInit(a_priority, BgType_Text8bpp, BgSize_T_512x512,...

Ok now I see from the examples that you have to copy the map in 1 line at a time when the bg gfx are wider than 256 pixels.

I have successfully loaded 256x512 backgrounds but when I try to load a 512x512 it doesn't appear on screen properly. Here is my code in a nutshell: videoSetMode(MODE_0_2D); vramSetBankA(VRAM_A_MAIN_BG); int bg = bgInit(a_priority, BgType_Text4bpp, BgSize_T_512x512, 0, 1); dmaCopy(bg_rockfieldTiles,...

You're right, and I suppose I meant it in a broad sense. I've been doing some research since creating this thread, and the consensus seems to be that hands on experience is how most professional programmers learn memory management techniques. I have found some good books on the subject on my own, en...

Hello, I've been messing around with devKitARM for a few months now and have been enjoying it immensely. However I'm a hobbyist programmer and self taught, and as such don't really understand all of the fundamentals of c++ programming. One of the areas I'm very weak in is memory management, which se...

Ok, got it. Thanks for clearing that up!

Previously, and currently, I was using the following grit options: -W3 -p -gt -gB4 As for oamInit(), i was using: oamInit(&oamMain, SpriteMapping_1D_128, true); With these options, I couldn't get the sprites to show color when used: vramSetBankF(VRAM_F_LCD); dmaCopy(main_gfxPal, VRAM_F_EXT_SPR_P...

My mistake-- when I posted this code I put dmaCopy(main_gfxPal, VRAM_F_SPRITE_EXT_PALLETE, main_gfxPalLen); That was a typo. In my program I actually had dmaCopy(main_gfxPal, VRAM_F_EXT_SPR_PALETTE, main_gfxPalLen); Anyways, I managed to get ext palette working, but it was a strange workaround. Inst...

Hey all, I was wondering how to properly copy over an extended palette? Would it be something like: /* 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, (u16*)VRAM_F_SPRITE_EXT_PALETT...
