Re: ds roms being flagged as adware?
Looked around and I wasn't able to find any information on duh web about this sort of issue. Even if that weren't the case I would have told you not to worry about it as the roms you get from here are safe. From my own personal experience, I've been using the roms here since like back in 2000 and I've never gotten any weirdness from them ever.
Antiviruses can be weird sometimes when using emulated anything, for instance most private servers for mmorpgs and such get flagged immediately just because of the way the emulation works. The AV is like "whoa, this is some weird coding and workarounds and that probably shouldn't be" even though you're like "yeah, it totally should!" so... TL;DR is it's very much likely nothing at all.
my anti virus (malwarebytes) detected 8 of my roms i downloaded as adware
theses are the roms i installed
mario 64 ds
kirby super star ultra
legend of zelda spirit tracks
pokemon mystery dungeon explorers of the sky
