Java for NDS Release 2

[wraggster]

Davr has updated his release of Java for the Nintendo DS, heres the full news from his site:

I know what you’re thinking…”That’s a horrible idea and you’re a horrible person for suggesting it!”

The main problems with Java on DS:
1. Interpreted languages are slower, the overhead is bad on a slower embedded platform
2. No direct memory access. Almost all of the DS hardware is interfaced by reading and writing directly to specific memory locations
3. No primitive unsigned 8-bit types. What were they thinking?

But…I went ahead and did it anyway, just for fun. I didn’t start from scratch, I took Torlus’s KVM port to GBA and used that as a base for getting it to work on DS. Right now, when it starts, you pick a .class file, and it will run it! In addition, using KNI, I’ve written a basic wrapper around parts of libnds, enough to read input from the touchscreen/buttons, and to move sprites around.

To use this demo, place kvm.nds, all the *.class files, and all the *.bin files on the root of your flashcart.
Run kvm.nds, then select a .class file to run. There are a few examples testing various stuff.
Don’t forget to DLDI-patch the kvm.nds

think this would ever be able to be implimented into a browser?

Probably not. I remember using Java on a 100Mhz Pentium in Netscape Navigator and it wasn't exactly blisteringly quick and that was with simple code, not what's used today.

There will never be Runescape on DS.

I really need to look more into this. I'm learning Java in my first real programming class at school, and while I did make a class for this that prints out rows of stars[1], I didn't do too much else with it. I wonder what else I'm learning could be applied to the DS here...

[1] it was a simple program. Calling obj.starGenerator(5) would give this as output:

*
**
***
****
*****
*****
****
***
**
*

Changing the number simply made it run more before counting back down. It was basically just an exercise in "for" and "while" loops.

Try porting a java based roguelike to the DS?

Isn't there already a fine-tuned Nethack port to the DS that doesn't use Java?

Runescape can be exicuted on the DS through a appilication called DS2win

Can this play mobile java games?
