Now for the flaws:The unit feels bulky and more than a little awkward

The wavy lines are still there during gameplay, but very slight and easy to ignore.- Which leads to the next issue regarding the 4th unit

I think the major thing that lack's in today's portable gaming units, is that they make them too small

Just to clarify something: This particular system is the Retro Duo Portable Core Unit

I would still recommend this unit, but for around the $50 mark.

I have heard that this unit is not compatible with some games, but we have tried about a dozen SNES and NES games so far and have not run into that issue yet.

So i figured it was just a bad unit

* I recommend never actually playing Shaq Fu; I only tried it to test compatibility.
