thanx all for the info and the LINKS! i didnt know they r still MAKING games for these. thats awesome someones puttin the energy into that. took yer advice and started a new thread in the wanted section. will see what happens. i have like 80 or more carts. havnt done a count. could be more. most r already real nice in boxes, my dig dug and tower of doom and thunder castle and some other harder to find r loose with instructions. i think tower of doom needs a manual. i think im gonna just get a full collection of whatever and then go from there! i found if u take the white cart inserts from the boxes and put it in a clear video tape cassette holder it clicks in perfect and doesnt bang around and see thru to see what it is next to my boxed stuff so i figure im good to go. thanx again. if anyone has spare boxes or instructions or inserts or more of those plastic cartridge inserts as i already burned thru mine! GRACIAS!.........acot
