Hacking [Release] DeSmuME - DS Emulator

[MasterFeizz]

This is a port of DeSmuME for the Vita.

Still very early in development.

Roms must be placed inside ux0:/data/desmume/

Updated:
Sound support
DS homebrew support
WIP - Multi threaded rendering (thanks to Xerpi)
FPS counter (thanks to Xerpi)
Basic rom selection
JIT (Dynarec) implemented
Video output scaled.
You can now switch between 3 video layouts by tapping the bottom right corner of the screen.
Saving should also work now.

Spoiler: Screenshots

Thanks for this! Testing Curious Village. I'll report back what happens.

EDIT: Well, it runs! Slow, but it works.

Wow, that was not expected so soon

you would have to put your vita in your eyes to be able to see that small image xD but it's still a nice work and happened sooner than expected!

I only have PSTV, so I never realized how small it was til now.

guesd it's displaying the original ds resolution... couldn't it be upscaled to fit the screen?

Yes it can, but I'll have to leave it for later since its pretty late here

No worries, i don't even have a vita but i was impressed with your work

Great work.

A portrait-mode for stylus-based games on Vitas would be useful, too.

Dat resolution haha

 

[laharl22]

Anybody can compile the xerpi version?

 

[zekepliskin]

Um... wut?

It's a bit tiny so we'd need screen scaling etc but wow, some sort of DS emulator on the Vita! Impressed.

Personally what I always thought would work quite well is not have the screens on top of each other unless you're running portrait mode. Have them side by side and scale - both screens are 256x192 @ 4:3 aspect so putting them side by side we could scale each to 480x360 @ 16:12 with slight letterboxing top and bottom to retain proportions and fit to width of Vita screen. You could take the Wii U Virtual Console approach and have the main screen bigger than the bottom but personally, I'd go with the side by side scaled option.

Incredible work. Glad to see the Vita scene picking up! Would love to see this developed to completion. I'm hoping the vita will reach PSP levels of homebrew.

That was fast as hell.

Nice work!

Can the analog be used for dpad?
