There are some artifacts in the form of lines when the camera moves, ie during the game. At least in both Zelda.

I'm having this exact same issue and I can't find any real documentation about it.

Ive used RetroArch iOS for about two years now and had it sideloaded on my iphone 15 pro along with Delta. Ive since downloaded and migrated most of my games and save files into the official ios apps bc the updating was just easier to manage for me.

I can confirm @Siigonis issues above w the current melonDSDS 1.2.0 core is producing strange line artifact in Spirit Tracks. Ive never moticed these issues in the previously.

I also tested Spirit Tracks in the most recent version of Delta which uses the melonDS 0.9.5 core and these lines are NOT present.

I also tried Spirit Tracks out in the Retroaarch ios DeSmuME core and the lines are NOT present in that core either.

I made a post w videos of the RA glitching and tje Delta non-glitching (for comparison) on the RA Support Discord a few days ago, but so far there's been no helpful responses.

I tried a different version of the Spirit Track rom to confirm it is not just an issue w the Rev1 rom i'm using and the line artifacts are in both. I also tried out Drago Quest 4 and don't notice anything, interestingly.

However, I did notice it significantly at the beginning of SM64 DS.

So this is happening in multiple first-party developed Nintendo titles with melonDSDS and not happening in other cores and (at least) in the melonDS 0.9.5 core inside of Delta.

How is no one else noticing this? It seems pretty significant.
