My dad flew all the time (still does till this day) so he had Tons of flyer miles and Marriott points so we would go to Hong Kong every year or two for awhile. Most people would go to like Disney but this was cheaper for us as the exchange rate back then was awesome. (I remember super sizing my McDonalds for the US equivalent of 14 cents when it was 39 cents here). One time he had way too many points that we got to fly Singapore airlines first class and they had Super Nintendos built into the armrests where you would pick a game on the screen and it would load instantly. I put 3 hours on Zelda for the snes and found out afterwards that it didn't retain your saves :-/
I did a quick Google search and apprentice they still do games.
As far as neo stuff it was pretty non existent everyone was all about snes Genesis PC engine and then eventually ps1. Once ps1 was in full swing I was picking up used PC engine and new sealed supergrafx games for next to nothing. At first they didn't have mod chips for ps1 yet so they would burn the games to cdrs and give you a spring that would let you open the tray while the game is Reading so you could load a real game like tekken and then pull it out after it checked to see if it was a real game then you would put in your CD-R and play.
Last time I was over there the halo edition Xbox 360 just came out so it's been awhile now since I been. I think if I went now it would be no big deal as there's nothing there you can't just buy online anymore :-/ seems like Japan would be way more interesting now especially with the cool neo stuff that seems to keep coming out of there.
