GBP?=game boy printer? Usually sellers wont bring odd stuff unless its worth something.
There is a swedish gameboy LE(Blue and yellow if you ment that one)
I collect mostly for 8 and 16-bit systems. Looking for a nice forum to interact with other Collector’s.
A couple of years ago I started to sell my PAL snes games and buy NTSC, both american and japanese games. With hope to do the same with some other collections.
I also host a expo in sweden with some friends called Retrospelsfestivalen(translates to the retrogamesfestival).
