I'm interested in puchasing a PC-FX memory card but I've had no luck on ebay or at any of my trusted online shops. If you'd like to sell a PC-FX Memory card please contact me by replying to this thread.
I don't have a BMP to sell but there's one up on eBay (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=4315&item=8114109000&rd=1). For at least the next 19 hours.
Got one! Thanks everyone. Funny little thing. I think it's great that you can replace the battery!
