Can't imagine it looking good on a big screen....
I don't imagine it'd look any worse than playing DS on a (new)3DS XL, it might even look better on the Wii U controller's screen if it's scaled properly.

After all, scaling is the major factor as to why DS games look bad on a 3DS.

there is one retail ds game released for jpn 3ds,Advance Wars Days of Ruin

however,nintendo never released retail version of japanese AWDOR, although it was contained in US version, finally they released the game in dsiware as redeem reward for club nintendo in 2013.
Very interesting! Thanks for bringing this to our attention.

So what you're saying is that it scales it better?

Nintendo have never provided retail DS games on the eShop, and is unlikely to start doing so. It's simply too late in the device's lifetime.
Nintendo's own games - no.

But multiple games went the cart-to-eShop route, such as Plants vs Zombies or Jagged Alliance.

Could this now be possible with a9lh and editing sysNand files? Sort of like the AGB_FIRM signature patching? Just wondering because I would love to see NDS on 3DS without a flashcart. I'll help test files if anyone needs me too.

No. Not right now, at least.

For those who haven't noticed my blog post:

You CAN convert DS stuff to DSiWare to cia (you don't even need to convert it to DSiWare, giving the ROM a TitleID at 0x230 is enough), but the reason you can't PLAY retail ROMs as a standalone cia is because retail ROMs try to access the gamecard, but since DS stuff runs on bare metal, and (in my undertanding) TWL_FIRM kinda just acts as a loader, it would require HEAVILY patching the WHOLE game code to EMULATE the gamecard, so no retail DS ROMs for anyone.

Please note that I said you can't PLAY retail ROMs! You can convert them, and install them, and the code will run, but will hang if it tries to access the gamecard, because it's not inserted. If you start a retail game installed as a cia, AND you have the gamecart inserted, you can technically play DS ROMs as a cia, since the CODE is loaded from the cia, but the ASSETS are loaded from the gamecart. This is the reason it's possible to dump a flashcard's ROM, (patch it if needed, like disable autostart flag, fix header, etc.), and install it as a cia, and be able to use the flashcard.

If you have any questions regarding this, I have researched this topic for two full days almost non-stop, so I know most of the stuff :P
