Nintendo DS Programming

Post by **tr1p1ea** » Wed 06 Sep, 2006 7:43 pm

This thread is all about Nintendo DS related programming, demos, comments and such.

Anyways, tilemap demo with animated tiles, scrolling, move a sprite around and collisions:

Yes i know the gfx are crappy, but its only a test

EDIT - Whats with these links? They just dont work for me. You're going to have to copy the text and paste it into a new window :S.

yeah could you paste some code, I wanna see whats going on. Though I don't want you to thread jack.

I think i will make another thread for DS coding, tomorrow though.

Code is in the zip file

My tilemapper was me doing the sprite routine in a for loop. There is almost no documentation on anything. I had no idea there was an easier way to do it.

hmm
what exactly is DS homebrew written in?
this looks like something I might want to try...

That has got to be the shortest answer to a problem. Well, almost, if you would have left off the period.

I'm looking into homebrew for the DS. I don't like this idea lf flashing the DS though, I kinda like the firmware and the pictochat and stuff. If you flash it, can you still use it to play real games, go to download play, and other goodies like that?

I hear tell that with newer firmware the GBAMP doesn't work, because the PassMe2 doesn't work if the GBA cart doesn't have any SRAM, and the GBAMP doesn't have any SRAM, so...

I personally will shell out the cash for a cart, I just need to go off and figure out which one.

PS: Good job on the demos. Are the registers set up fairly the same? Like, is switching over pretty easy?

I tried to answer just "C", but it wouldn't let me. The M3 CF emulates SRAM correctly and I did not need to use flashme or lose any of the default things. I actually still play games the normal way. For the most part. Supposedly most of the registers are exactly the same. Every guide I was referred to (with the exception of one) was written for the GBA.

Im pretty sure you will be able to get away with not flashing your DS. I have a SuperCard Lite and a MK4-Key which work nicely.

thegamefreak: Nothing is lost except the warning/health screen that pops up when you boot into DS mode, and even then theres a version of flashme that doesn't remove that. All flashme does is allows a GBA flashcart to boot into NDS mode, and add firmware protection in case you somehow brick the DS. That's all flashme really does. Pictochat, download play, and any actual commercial cart you put into the DS all still work like they always would.

Also if you're not sure which device to get, I suggest M3 or Supercard for universal purposes. GBAMP has too many limits.

Really? normal ordinary C? I've done a fair amount of c programming. Oh well, I've really got too many other things going on to fit DS programming in to my life.

hmm, it seems a mod didn't like my previous post. Anyway, I posted just the letter C without a period or anything, just to show that it could be done. I'll do it again if you want proof, TFG. You just have to know what you're doing.

too bad...I don't know C, and I've got too much going on right now to learn a new language.

I did, too. It was also deleted.

Sort of, on the just C thing. The language and al is the same, but to do anything with the hardware you focus more on writing to specific registers. You have to download (or create) a library of pointers to these registers, which are just memory locations, and then write to them a specific way to get the hardware to know what to draw. Although the language is C, the actual methods of coding vary greatly from your everyday computer porgramming.

Most of the stuff that's unfamilar is just writing to lists. They are memory mapped, so it's pretty easy to do them. All of the program flow and data manipulation stuff is just like C.
