DSemu: The Next Generation

[Two9A]

Morning, all. May I draw your attention to the (former) DSemu homepage, wherein will be found, for the first time in months, news.

Two9A has returned to work! Welcome back man!

 

Thanks for the news, it's always welcome.

[Two9A]

Alright. Progress thus far has been relatively quick, but I fear that things will slow down/crawl to a stop very soon now. Up to this point, things have been simple; I have a large percentage of a shiny new portable ARM7 core, a tiny bit of GBA bitmap graphics, and key input, all underneath a new portable (FLTK-based) GUI. From here, it gets difficult, and I may be tempted to simply hack in doublec's work on the DS components.

 

Now I know you're clamouring for screenshots. Very little in the way of demos runs right now, but there are a few simple ones that seem to work fine. Images follow (note, they may not appear immediately, as there seems to be an issue with the server):

 

 

The latest source should be available at http://ng.dsemu.org/dsemu-ng-20051008.tar.bz2

 

Feel free to check it out.

Sounds like work is progressing well... I get a DNS error on your server. I cannot see any images or download the source.

Yeah, my DSL line happened to go down the very minute I posted the message, and stayed down for like 3 hours. It's all back up now.

Are you working on a new DSEmu or are you helping doublec?If you are working on a new Version:When will you release it?

 

Sorry for my bad english,because I am German.

this actually looks like the most promising emulators out there. Should make homebrew a lot easier.

To clarify things. As of right now, the DSemu project is termporarily forked; master Double's working on DSemu, and I've got DSemu-ng. When I've caught my code up to doublec's, I'm hoping to integrate/replace the current DSemu tree with DSemu-ng, hence merging the projects.

 

To answer your other question, there won't be a release; even though this is "another emulator", it's intended as a merging replacement to DSemu.

Very nice...keep it up.

[Two9A]

Regular updates? Never. Anyway, I took a break for a couple of days, and came back to the code. Only to find that a couple of demos break horribly, RValentine being the most notable. Now, I spent all day hacking stuff in to find the problem. I didn't find the problem, but I did hack the stuff in. (screenshot follows)

 

 

Perhaps tomorrow or the day after, the bughunt can begin.

Hi there,

 

Thought you might like to know that I got this to compile and sort-of run under OS X.

 

I had to make a couple of fixes however.

 

The DSEMU version number wasn't a string, so I changed the Makefile.osx to echo the thing with quotes around it.

 

The path to gl.h didn't work so I changed it to <FL/gl.h>

 

I had to add gbammu-dma.c to the makefile as well.

 

After linking you need to execute 'fltk-config --post dsemu' in order to add a small resource fork so that the UI functions.

 

Nothing seems to run correctly however. I tried the copperbars and mode3demo.bin files and neither works. copperbars displayed nothing and mode3 looked like this:

 

 

Ah well, at least it kinda goes...

 

This is version 20051014.

Have you thought that the MacOS platform is Big endian, and that intel x86 and ds are both little endian.

 

You can try swap every bytes you are reading.

 

Good luck guy

That's very kind of you to point out, but the feature's already there. The problem is that I found a bug in the MMU yesterday, where the bytes are being swapped twice for MMIO memory. So I've prised that out, and you might have more luck with the next release, when I get the time to put a tarball together.

Cool, I'll keep an eye out for it. Will you be putting back the nds files in the next one?

[Two9A]

DS functionality's a long way off yet. I'm gonna try to attack sound first. If I can add one channel of sound, that'll be a lot more than DSemu's ever had before.
