- nds/touchscreen: works also in debug-window (not only in separate game window)

- nds/touchscreen: initializes calibration also when booted via bios/firmware

- nds/div/emu/help: DIV0 or MAX overkill: 32bit result is reversed-sign-expanded

- nds/div/emu/help: reserved mode3 is same as mode1, result/remain sign-expanded

- nds/div/emu/help: DIV0 sets remain=numer, result=+/-1 (sign opposite of numer)

- 3d/log: auto-indent within begin/end, auto-wrap-indent for NxN matrix params)

- nds: re-init fpu-mode for 64bit INTEGER div/sqrt (required after opengl calls)

- 3d: fixed SCALE command (applied only to one matrix even in simultaneous mode)

- 3d: fixed mtx_load_4x3 command (applied to both matrices in simultaneous mode)

- 3d: emu: fixed vec_test (x,y,z,0) (4bit sign, instead 1bit sign+3bit integer)

- 3d: texcoord-transform fully software emulated (without GL_TEXTURE matrix)

- gba/help: added note on more complex invalid tiles with multiple BGs (jasper)

- 3d/help: added decal/modulation/toon/highlight chapter, and texcoord chapter

- 3d: texture 4x4 texel compressed format (incomplete, without interpolation)

- 3d: texture translucent formats, palette formats optionally color0 transparent

- 3d: bugfixed vtx_diff (9bit fraction is meant to be LSBs of 12bit fraction)

- 3d: material0.bit15 directly sets vertex color (for N's "cube" demonstration)

- 3d: light/material/normal with forced begin/end-outbreak on GL_LIGHTING change

- 3d: calls gx_process_fifo to free-up gxfifo (when possible aka no swap active)

- 3d: get framebuf: reverses red/blue by table (for match-up with nds 2D engine)

- 3d: explodes (1)-5-5-5 RGB textures to "unpacked" OpenGL RGBA 8-8-8-8 format

- 3d: supports 16bit I/O-writes (eg. metroid demo: 16bit STRH to CLEAR_DEPTH)

- 3d: textures (metroid demo: "nintendo/actimagine" shown before intro-movie)

- 3d/help: added note on END_VTXS being a dummy command (no effect on hardware)

- 3d/help: added note on depth test, and on POLYGON_ATTR applied at BEGIN_VTXS

- 3d: enabled Depth Test, and emulated Depth Test modes (either Less, or Equal)

- 3d/iomap: displays VertexColor setting (Port 480h aka Cmd20h) in F10 screen

- gba/video: bugfixed rotscal tile-map mode (bugged since v2.2f) (thanks jasper)

- 3d: converts fixed-point-to-float by FMUL 1/1000h (faster than fscale or fdiv)

- 3d/help: added notes about clipping, and about light vectors and normal vector

- 3d: retrieves DIB bitmap data by movsd (glReadPixels doesn't seem to work)

- 3d: supports begin/end quad/triangle/strips and all variants of vtx-commands

- 3d: forwards (software calculated) projection/modelview matrices to opengl

- 3d: supports clear color, clear depth, and applies viewport setting

- 3d: supports vertex color, and polyonattr alpha/wireframe/front/back settings

- 3d: pre-calculates 5bit R,G,B,A float values (for fast conversion via table)

- 3d: calls ChoosePixelFormat (killer-slow) (only if needed, not for 2D games)

- 3d: retrieves gl- and wgl- and PixelFormat proc addresses (quite fast)

- 3d: loads Opengl32.dll (killer-slow) (but, only if needed, not for 2D games)
