Ah, I should've guessed.

9. Can hardware scrolling be done on tiled backgrounds, and if so, does it move by pixel or by tile width (8 pixels) and how is it done?

8. How are pixel transparencies handled using 256 paletted color (since there is no transparency bit as in 16-bit color mode)?

Re: Homebrew Project Questions

it doesn't need to be, but you need to write to vram at least 2 bytes at a time (1 byte wont work) and using one of the existing functions will most likely be faster than doing it yourself. How come 1 byte doesn't work? 7. In dovoto's 4th day tutorial , he says that the 11th and 12th bits in a 16-b...

6. Why must tile data be written to video memory using a bios call (swiCopy) instead of writing to the space directly?

Re: Homebrew Project Questions

Alright, thanks for the clarification. I've now successfully compiled and run my demo, which is operating as intended on both DeSmuME and the hardware itself. By the way, vuurrobin, according to the libnds src, touchReadXY updates the pressure and raw values too, it just returns them in a touchPosit...

Re: Homebrew Project Questions

Don't you need the ARM7 code for retrieving the other key input (touch, x / y, lid)? What makes combined projects so much more difficult? Also, if it's no longer used for those things, what is the ARM7 used for now? As to whether it would be easier to start with any of the other examples, I cannot s...

Re: Homebrew Project Questions

The name of the folder with the top level Makefile is called "tileDemo1", but when I searched My Computer there was no .nds file with that title created after the make completed without error. There were, however, .nds files created in the two subfolders, arm9 and combined, called arm9.nds and combi...

Re: Homebrew Project Questions

5: I followed the basic compilation instructions at the bottom of dovoto's day 1 guide to make a demo I wrote, but I don't know what the resultant file should be. Is it arm9.nds? First I thought it should be the combined.nds file but when tested on desmume it produced a demo from drunkencoders.com s...

Re: Homebrew Project Questions

3 & 4: Ok, cool.

2: I thought I was looking at the source - it's labeled libnds-src-1.4.0 on sourceforge.

EDIT: Nevermind, I wasn't looking at the .c files. Now I see the code which I thought was missing.
