If you browse Youtube for 3DS Emulators, most of them are crap and require BIOS. Whatsoever the one i found seem to be... how i can tell... realistic? 1. The title says "Proof of Concept", meaning its not finished, and cant be downloaded. Almost all 3DS emulators videos do have a download link. 2. Lag. The description actually says so. ".It's * lag * like absolute sh*t.You can't believe it." Almost all 3DS emulators videos do not lag, and plays the "roms" perfectly. 3. The person itself hates the fake BIOS emulators, as seen in the description. 4. The screen is * tiny *, probably rendering bugs. Fake 3DS emulators seems to not have bugs. 5. There is not tabs like Help, About, Tools, Cheats or whatever. Simply because we didn't discovered that actually. Other fake 3DS emulators does have theses tabs. 6. Absence of sound. The desc says it. All other fake 3DS emulators does have sound.
