How can I tell grit to create a background image without transparency (i.e. without using palette color 0) ? When converting the image http://ryouarashi.ry.funpic.de/grit_source.png using the options (.grit file) -ftb -fh! -g -gt -gB8 -gT FF00FF -m -mRtf -mLs -p i get transparent areas on the backgr...

Add #include <nds.h> to the include file.

M3 Real doesn't pass ArgV, which libfilesystem needs. Use HomebrewMenu to load your file. libfilesystem works on Emulators, because they emulate some kind of "Slot 2" boot, so the lib can access the whole nds file. If you have the GBA module from the Perfect bundle or some other Slot 2 RAM, you coul...

I'm writing a iprintf-like function for printing text using a 8x16 font to a text background. My font contains the standard ASCII character set for codes 0-127 and language specific characters starting at 128, e.g. german umlauts: 128 = 'ä', 129 = 'ö', 130 = 'ü' (and so on) However, output is stoppe...

Use %lf for doubles (=64bit). %f is for floats (=32bit).

no$gba (and maybe other emulators as well) don't emulate this, but it works fine on hardware (just tested the BoxTest example on M3DS Real). Note: In the BoxTest example the printfs for polygon and vertex count use "%i", which give incorrect output when the number of digits changes. It should be som...

You cannot directly load a bitmap into a text background. A bitmap stores the image per pixel, while text backgrounds use tiles of 8x8 pixels. First, you have to use pagfx or grit (havent used the latter yet, pagfx works fine for me and is easy to use) to convert your bitmaps into tile and map data ...

Updated to latest libnds and arm7 and redownloaded HomebrewMenu, recompiled and everything works fine : -)

If you use extended palettes, each BG layer gets 16 palettes of 256 colors (4k colors total) to use. Each tile can be assigned one of these inside the map entry (theres a macro called something like TILE_PALETTE(n) which is or'd to the tile index). The default palettes are 512 Bytes (256 x 16bit col...
