A new version of the popular DS emulator. The latest freeware version has been uploaded to the downloads center (2.6), and 2.6a can be obtained from his site for a PayPal donation.

Here's my analysis from the other thread:

Notable improvements include:

Savetypes are automatically detected.

Mario and Luigi: PiT no longer crashes when hitting a save block.
Need for Speed: Carbon's races are now visible.
Super Mario 64 DS now has shadows, runs at full speed with little to no frame skipping.
Zelda: Phantom Hourglass and other cel-shaded games no longer have lines on the edges of the polygons.

The 3D renderer has been sped up 2x, but won't affect most 3D games. This is because the nocash 3D core is to the point where it takes way less CPU power to emulate than it takes to emulate the DS's ARM7 and ARM9 CPUs.

3D games use to run at 3% on my crappy PC now they run at 39% ... 100% in 2D games

if you have a new pc i dont see why this emulator can't run games at full speed

what a douche, emulators are NOT to be made commercial
what a douche, brains are NOT to be turned off

come on, without martin korth there will be no slot1 devices and yet it doesn't seem to matter for most that he did not get any money from it. This man has done a lot for the ds scene, $2.50 is really a small thing... and if you want you call the program little$nds.

It's called nocash, because he has no cash.
Give the man $2.50, it's well worth it. I paid and I don't even use his emulator.

I paid, and I never pay for such things. Btw: Is it possible to run ds homebrew emulators etc which use a file system on no$gba?
You could create an FCSR image with the tools from http://gpf.dcemu.co.uk though that's a lot of work, and it doesn't always work right. DLDIrc has automatic FCSR image creation in it if you want to try it, though I've had more success doing it manually. Let me know if you want manual instructions.

I wouldn't pay for an emulator unless 100% of the games were working at full speed.

But then again, I don't bother to emulate handheld systems on my PC. Kinda defeats the purpose of a handheld, don't you think? I'm sure I could find the latest version for free if I cared enough.

BUT

I would imagine the dude is charging that nominal fee for the latest version just to see how much continuing interest there is in his emulator.....not to mention enjoying some deserved cash for his efforts and to keep him interested in continuing his improvements.

I DO understand that even though I don't care about emulating a DS on my PC (especially if I have to pay for the privilege, especially when you consider that as soon as he comes out with another version, the old one will become free....and it's still not 100%), that many people do care. So don't take my reply the wrong way.

Try to see things from BOTH sides of the fence.
