melonDS 0.9 is out!
It's been forever, but, finally, here it is. melonDS 0.9.

And it's big.



So, what are the highlights of this release?


- JIT recompiler

Brought to you by Generic (aka RSDuck), the new JIT recompiler enables melonDS to run much faster, and quite often reach fullspeed even when emulating DSi titles!

There are a few settings you can try out to get the most out of this JIT. While it has been heavily tested and worked on, it's still imperfect.


- DSi emulation

This is the other flagship feature of this release: melonDS now emulates the DSi!

You will need a NAND and firmware dump from your DSi, as well as augmented BIOS dumps (such as those that NO$GBA requires). The following BIOS dumper can dump the required BIOS files from a homebrew-enabled DSi.

Do note that this is still experimental. For one, direct boot will not work under DSi mode. Not everything is running yet, either, but we're getting there. melonDS does not yet emulate some hardware like the DSi cameras (but on the other hand, emulates DSi wifi).

melonDS has a small hack to bypass the region check. However, DSiware titles can't be run standalone yet, they will need to be installed to the NAND.


- GBA slot support

melonDS now supports loading a GBA ROM to simulate having a cartridge in the GBA slot. This is done by selecting a .gba file while your game is running. Note that we don't support emulating the GBA in any way.

We also support the Boktai solar sensor addon. Support for more addons is planned.


- New Qt UI

This means we get to do more without needing to work around the limitations that libui had. For the end user, this also means a bigger binary, but on the other hand, on Windows, all the dependencies are linked statically, so melonDS does not come with external DLLs anymore.

The new interface adds features that were long requested: for example, you can open the emu settings dialog to point melonDS at your desired BIOS/firmware/etc files, without needing to move/rename them around.


- Cheats

This is another popular request, and here it is. melonDS lets you enter Action Replay codes to mess with your games in whatever ways you want.


- DLDI

melonDS now supports letting homebrew access files and directories on a SD card image. Note that for now, you will need to provide an image file, melonDS does not yet build such images on the fly like DeSmuME can do.

Similarly, you can also use a SD card image to emulate the console's SD card in DSi mode.


- and the rest!

As usual, there are plenty of little improvements with this melonDS release, that are too many to list here, but you may discover them on your own! Or find them in the changelog (which we are still busy compiling - it's a big release).


Enjoy!

have you tried doing it again in Diamond edition?

EDIT: also there's a bug which can lead to lockups in the underground in Pokemon D/P/Pt and if the C-Gear is enabled in Pokemon B/W/B2/W2. See this thread for more infos: http://melonds.kuribo64.net/board/thread.php?id=278&page=1

savefiles or savestates? The latter aren't compatible between versions.

Congrats Arisotura & melon team for pulling this version off, with all fancy new features, starting with the ARM dynarec.
Right now MelonDS stands as the best x86 DS emulator, at least for my books.
I can run full-speed Mario Kart DS at 8x resolution on a 8 years old laptop with a Kepler mobile GPU.
And I haven't even started using the more advanced features (DSi, wifi, etc).
One last thing for my wish list: a full-screen feature & shortcut button would be great with the new & fancy QT-based GUI.
Keep the good work guys, and congrats again. I'll keep an eye on the future emulator developments.

Has anyone gotten WiFi to work on this release? I can't trade pokemon because the blue screen comes up. What settings in npcap?Which dns servers to use? And do I use Local Area Connection or the WiFi option in Wifi settings via melonDS config?
