The Lynx on DS, is this project feasible?

I know I see it when testing home-brew stuff, but everything else works for me... =(
The ".lnx" files should include a header which is needed still, there are also ".lyx" files which doesn't (shouldn't) have a header.
I don't know if that helps.

here you can test if your rom is in ".lnx" format.

Thx @FluBBa it works !

I successfully launched Batman Returns!

If anyone is interested in the method here is what I did:

1. find and download lynx games in .lyx format (don't ask me, it's very easy to find on Google)

2. convert games here:

https://atarigamer.com/lyxconverter

3. download the .lnx file + header

And there you have it

I did this because my original .lnx files, the first ones I tested, were not recognized in the lnx2lyx converter

Thanks a lot, it works now.
I noticed that avaialble roms on the web in .lnx format are with a header, and sometimes not.
Now is pretty cool to run tiny Chip's Challenge on our device.

Only FluBBa makes it possible !

Double Dragon = 27 fps on DSi, not that bad !

Indy13 · Oct 3, 2024

I've been converting my complete romset (commercial games + homebrews) since yesterday so I haven't really had time to try many games but for the moment the ones I tested work well, here is ( very small^^) list:

-Batman Returns
-Double Dragon
-Electrocop
-Klax
-Rygar

So, uh, a little progress =) I just got my asm cpu spinning in the emulator, double the FPS just like that.
The next big speed-up is probably the sprite blitter, that will take some time to re-implement in asm.

This is awesome news! I can't wait for the next update

I'm still converting my romsets. I haven't had much time to devote myself to it since the last time (that said, it's still progressing ^^) but I wanted to know if this new ASM processor was in the source code on your github or not yet in order to compile the nds file myself to test on real hardware.

On the other hand I don't know if you planned to make borders later but on the atarigamer site the borders of their online emulator are not bad at all, I saved the image, I'll give it to you attach it if it could ever be useful in the future, who knows

I leave you two versions, the original version and a resized version 256x200 pixels in 8-bit depth

This is a pretty exciting project! It's always great to see more games become playable on DS. And I don't even like the Lynx!

Hi @FluBBa , hope you're well

I tried to compile HandyDS but I got an error message that appears at the end of the process telling me that the lynxboot.img file is missing, so I added the lynxboot.img file several times at a time at the root of the main directory like this:

but also in the source folder like this:

I also added the ARMMikey folder to test it but in all the ways I tried from the simplest (without any addition) to the most complex (with lynxboot.img files everywhere) I always come across the same error message, could you tell me what I missed and where should I put my lynxboot.img file?

Here is the result I get:

PS: I also tried adding a lynxboot.img file to my devkitpro/devkitARM directory (on my C:/ drive) but I get the same resut unfortunally

I got it to compile after editing Cart.s file, line 42.
Change from
.incbin "roms/lynxboot.img"

to absolute path e.g.
.incbin "c:/yourpath/roms/lynxboot.img"

I'm sorry for the confusion, I try to keep things under wraps for a little bit more.

Oh sorry buddy, I didn't want to embarrass you with my somewhat inappropriate curiosity, I completely understand, I will try @draftguy123 's solution and in the future if ever I can't compile the source code, I'll be patient, no problem

Once again, sorry for my clumsiness.
