A list of issues that come from the games themselves, and do happen when playing on a DS. Intended to avoid chasing phantom bugs.


Flickering: may happen on a DS, it is attenuated by the LCD lag. Typically used to simulate transparency (NSMB coin bubbles) or cheap antialiasing/filtering (Picross 3D).

Slight flickering also happens when 3D is displayed on both screens: 3D graphics are 18-bit, but the capture degrades it to 15-bit. On hardware this is completely attenuated by the LCD lag.

Mario Kart DS

Kart shadows look wrong under certain angles. This is a limitation of DS shadows; those work best with convex shadow shapes (which MKDS kart shadows aren't).

Super Mario 64 DS

If you notice a blending issue, be sure to check against hardware before reporting. This likely applies to a lot of other DS games too.

The game is full of glitches. Be sure to check against that list if you observe abnormal behavior.

Rayman DS

First level, when you meet the Globox kids. Missing polygons on Rayman. Also happens on hardware.


Cube shadow is glitched and has very poor draw distance. Also happens on hardware.

Thanks. I guess I'll go through my thread to see if anyone posted these issues.

Ultimate Mortal Kombat
Sometimes there is a visible gap between polygons on the fighters:

melonDS had a lot of problems with this game in the past where there would be gaps between basically everything. So some might assume that there were still lingering bugs in the emulator causing this, but it happens even on real hardware.

It seems that Melon DS doesn't work with any MKDS ROM Hack that uses ASM Hacks,
it doesn't go passed the Nintendo Logo on these.
