I have an extra Cratermaze. Someone wrote game codes on the back of the manual and then tried to erase a couple of them. I'd rate the manual "good", the hu card is very good. It's up for trade here;

Also, just an update on Shockman for you. The copy I purchased off eBay shipped today. I also secured a copy off a local seller that I'll have in my possession tomorrow evening.
I'd prefer to trade for other TG-16 games rather than sell them. I'm not sure if you have anything in your collection yet you want to unload.
Allow me to introduce you to our youngest member. Lilgrafx is 16, right Lil? May be 17 now, hell I dunno. Basically, the turbo is a new, but not too new, thing for him. Its doubtful he has any to trade, altho he may just. But, I doubt it. Last year he won a raffle from BlueBMW, that netted him a Turbo Duo. Nice huh?
Basically, he is trying to get his collection to grow too.
I wish my 17 year old was into the system as much as Lil. My girls like it, and play it... But they prefer their DS systems or Wii, or 360...you get my drift?
