I am much like you, but I've gone like the pendulum of time on this one.
When I first started I made a name for myself (with this nick) over the last 10 years by doing Pasofami work, then into documenting the NES header format and doing a mass load of NES game releases. Beyond that I used to way back collect a heap of games for the NES, GB, SNES I didn't get a chance to play. I spread out a bit from there to systems I didn't have like the Sega things and NeoGeo arcade (and portable) but in the end I ended up owning some of Segas stuff and the NGPC, but all it, even a Turbo Duo went up for sale and I parted with the stuff. The one I dabbled with fairly for a bit and never did own for a brief time was the MSX. After that though in the last few years I've become sick of the gross amounts of time involved and even more the cash and I've sold off all my Sega, NEC, SNK, and Sony stuff and decided it's more time/money economical to pretend it's the 80s and I can just have 1 system and 1 portable to play with...so now I'm just back to Nintendo and with the emulators I just dink around with the GBA mostly but do bother with zsnes updates and pj64 (n64) too...oh and nestopia when it sees a revision.
