Re: How do I make a3i5 and a5i3 textures?

grit converts from from any rgba32 file. any serious bitmap editor can handle alpha. but you'd be well advised not to use TGA, as TGA is the worst format ever for 32bpp files. Like if you drop those in photoshop, theyll malfunction until you do some black magic which is idiotic. You can drop the sam...

Re: Linker is adding extra crap (Unreferenced library code)

youll also see sections .ARM.extab and .ARM.exidx in the bpapi.o ; exception handling junk that isnt in dwedit.o. its not too surprising that gcc also emit an extern reference to the exception handling code into that file when it emit the exception handling data..maybe to make sure that the exceptio...

Re: any way to make more use of space?/improve drawing dista

I dont know what a separate main file are. If youre asking if you can load "nitro-engine" files without all the associated machinery of nitro-engine, that sounds rather unlikely, doesn't it? You may have to do quite a bit of picking-apart of nitro-engine if thats the case.

Re: Heavy calculations on nds original

if it runs fast enough that offloading a share of it to the arm7 even makes sense as an optimization, then you're close to the goal anyway. just optimize it by a factor of 2 and youll have nailed it.

Re: Heavy calculations on nds original

the time to calculate one mandelbrot pixel may be more than the fifo synchronization time, especially if you use floating point maths. but since you havent even made your mandelbrot viewer yet on the arm9, it seems, you have no idea how fast it is running, making this a premature optimization.

Re: any way to make more use of space?/improve drawing dista

Hardly anyone uses the depth image and even fewer people use the back plane image. Those will be available for textures in almost all cases. Dedicated is a poor choice of words.
