A weird controller attachment that clips on the ear lobe and it only works with one Japan exclusive game, Tetris 64. It detects your heartbeat and adjusts the game accordingly. A shame it is not supported by horror type games.
N64 Tetris 64 Import - $10.00 Ebay
Oh, I had to get the game to try the Bio Sensor. The four player feature is decent. The blocks speed up depending on the heartbeat. Frankly, I couldn't get too excited over the falling blocks. Maybe attach a vibration puru pack to it and see what happens.

The game was praised for its multiplayer mode, which at the time was the only Nintendo 64 Tetris game which allowed 4 player mode, while most puzzle games still had not made the step into the four-player arena,
PS1 Pocket Muu Muu - $5.00 BookOff
I already own a Pocket Station, bought some time ago. Of all Pocket Station PS1 support discs to buy, this is one of the best with 100 Pocket Station games to dump. Now if I can figure out the "Jumpin Jack Flash" inspired game to unlock the "downloads".

PS1 Metal Gear Integral - $7.00 Bookoff
I bought this to get the Japanese voices as in the Tokyo show demo that is shown in PS1 Metal Gear VR. The Japanese language really seems to add impact to the game as in Dreamcast Shenmue II. Curses, this version is redubbed to English! Ah well, at least it has the first person movement view as in the PC version. The VR levels are also included as the third disc.
Game Cube Medal Honor Rising Sun - $5.00 Swap Meet
Already have the PS2 version, bought for the GBA link feature. Use the small screen as a map and stats viewer.
PS2 Ace Combat Zero - $5.00 Bookoff
Another of the Ace Combat Series. Disappointed that my USB PC Flightsticks are not supported. Even my Saitak PS3 USB Flightstick does not work, looks like only the designated PS2 Ace Combat Flightsticks is supported. Still, a great game flying older jets from the 80s and 90s.
PS1 SCPH-7501 Collection - $20.00 Swap Meet
Seller wanted twenty five, I offered fifteen for just the console and a couple of the games. He wouldn't sell it separately and stated twenty and "get all this crap out of here". Some of the games were originals, notably Odd World. What drew my interest was all the CDR copies in the cases, a sure indication of a Mod Chip. Confirmed after I got home the CDRs all work! The 7501 series is the best model for both the parallel port and the best music CD player in a console; the beautiful Sound Scope Player.

Sharp eyed PS1 owners should be able to spot the originals from the CDRs.
