I'm using DS Lite with R4/wood and as for me sound button (select) works fine for wsc games on latest release (0.3.6). Also there's no issues while launching the game.

The main problem of the DS fat/lite is the lack of RAM. Many games cannot be launched. The speed is OK.
To me, adding the abality to use a RAM expansion for old hardware would be very nice (same for NGPDS)
I wonder is it possible to fix some PCM sounds or disable. For example Kaze no Klonoa doesn't shout "Wahoo!" while jumping, but there's some shattered sounds instead. (as for me, better if he could be quiet, however I can used to this scratches even I beated the whole game lately and it's pretty great. Moonlight Museum In gray colors still feels and looks way better than gba competitor. There's more dificulty and has unique timing levels) The same shattered sounds are in example in Puyo 2, while moving a jellybean, or select stages. It makes unplayable with sounds.
In first post we read...
For ws games only black and white color pallete works... there's some options that provides other colors (i guess like with custom color polarizer effect) but it won't work for me. It would be cool to add some colorizing effects like gbc does for gb games. Let's say geen-blue background palette and red tones for sprites. Or even better, Wonderswan has 3 layers (background, foreground and sprites), I wonder is it possible to give each of them different palette. I did some screenshots of separeted layers with oswan, edited colors and join them again, so this is how it could look like.
Anyway thanks for improving this emu. I'm happy how great it works for ds lite now and really enjoy it.

so that explains the current state, I wonder if adding sample support will slow down emulation, but maybe some speed improvements are still possible. Looking forward for it.

@FluBBa - had a really enjoyable sit-down with this emulator this weekend. Judgement Silversword is a must-play. I also got a chance to really dig in on Dicing Knight which is brilliant (apparently it was a homebrew that went commercial). The only problem was a bit of slowdown - it seems to be close but running about 80-85% normal speed on the DSi. I realize you're pushing maximum speed with some tight assembly code... not sure if you've tried a frameskip (say, rendering 75% or 50% frames) ... if that game could come up even just 10% in speed (a tall task, I know) it would be an example of a system exclusive that MUST be played by every classic gamer.
Thanks for your efforts here!

Yeah, same with (almost) all games, the WS is default configured to run @75Hz, Firelancer is a home-brew that actually changes this to 60Hz to get more time in VBlank. I might take a stab at changing the DS update frequency but I'm not sure it can run @75Hz.
I will take a look at ch2 sample playing, at least turn it off if I can't get samples playing easy.
Hm, I can't get Makai Toushi Sa-Ga's English patch to load. I get a "File to large"[sic] error. I am not sure what I'm doing wrong as someone else in the thread seemed to have it booting. I have the BIOS installed and am using an AceKard 2i on a DSi XL.
You use a flash card meaning you are limited to 4mb RAM which is not enough to load the ROM. You need to install Twilight menu on your internal SD card. You will gain access to 16mb RAM and 133Mhz CPU clock.
Using Twilight Menu, the Makai Toushi Sa-Ga patch now loads, but it seems to have a couple issues.
1) The text boxes from dialogue do not display properly, as shown below.
2) The music seems to run a bit slow. Not the game itself, as running results in smooth scrolling, but just the playback of the music.
Thank you for your hard work on this!

The WonderSwan actually runs at a higher refresh rate than the DS, so that's why the scrolling seems smooth but the sound is slow.
It is possible to increase the refresh rate of the DS to make it run faster, but that'd be on the developer's side.
So, after a lot of work on the CPU core here is a new version.
* Fixed flag calculation for most opcodes.
* Fixed emulation of undefined opcodes.
* Fixed settings to disable Bg,Fg & Spr.
* Fixed default sound volume on WSC/SC.
* Optimized the cpu core.
* Tweaked behaviour of timers.
* Mute Ch2 when playing samples.

I didn't check much, but Magical Drop works now, great! Kaze no Klonoa doesn't have the shattered sound samples, cool, but my first thought isn't too silent now? 
Maybe better way is replace samples with regular chipsounds, patching the game. (I know it's not gonna happen) Also Guilty Gear Petit some sound channels that worked fairly ok before, are off now. Really Big Thanks for the update and your work, good to see it's improved again.

@FluBBa - you are man, myth and legend!
Dicing Knight seems to be pretty close to the proper speed... and if you guys haven't played DK you NEED to!
Judgement Silversword was pretty damn good before but is buttery smooth now.
Rock on!

The update makes this emulator quite a bit better. Not a lot, but a bit. Magical Drop runs full speed from what I've seen (My eyes might be at fault here though), and there's a slight performance boost across the board. I agree with wavemotion on Judgement Silversword, too bad the controls are finnicky. Music is still slow in most games
Are you by chance running NitroSwan in an emulator?
I do all my development running it in DeSmuME and wasn't really satisfied of the speed, now I have tested all games on my DS-Lite and almost all games runs at or very close to 60FPS. In the "Options" tab now under debug you can turn on the FPS meter, please report on any "slow" games.
No, I never test this stuff on emulators. In fact I tried 4.0 on my DSi XL multiple times
If you're running in DSi mode no games should ever dip below 60FPS, if this is not what you experience then something must be different on your end and I can't figure out what it might be...
Preliminary test on my DSi shows that 75Hz LCD updates should work!
This will be an option to allow changing the screen refresh rate, but it will be dynamic according to settings from the game (eg Firelancer will still run at 60Hz as intended).

Here is a version with support for running the DS(i) in 75Hz, this setting is under the Options tab -> Settings -> Allow Refresh Change.
* Fixed background for PCV2 mode.
* WS refresh rate can control NDS refresh rate.

Edit: I fixed the FPS meter and changed the binary on Github, hope that worked.

The Rockman/Megaman games are finally running at the intended speed with this new version!
Thank you!
