Shenske, you say you'll put the manual in one of the sleeves, my concern is ive come across games with manuals at least 1cm thick, and im doubting the sleeves can hold something that thick? what ya reckon.
BTW, im from down under, and im looking at doing this, myself, again after a failed attempt a year and a half ago due to lack of suppliers. Ive got a different brand that supplies, 1,2,4,6,8,12 disk cases, ive got some 6,8,12 samples but havent measured them up yet. Gona order some 4 disk ones and see if there a lil bit smaller and closer to the original cases ps1 games came in. If they are ill be working on a Pal template for this project, for us retail pal case fiends.
