Haha, I had three of those Tiger Handhelds - Simon's Quest, Mega Man 2, and The Simpsons. I could never beat SQ because I kept falling into water pits in one of the final levels. Nice to see that they preserved that element of the real game. I remember MM2 and Simpsons actually being kinda fun, though I always played the latter on mute since it had incredibly annoying music.
I also think I had a Ninja Gaiden wrist game. I'm pretty sure I broke it the day my mom bought it for me. Those games had the least intuitive controls ever.
It'd be hilarious if someone found a way to emulate these.
