I just remembered that after publishing Game Boy World 1990 Vol. 1 on Amazon, I never bothered to upload the PDF version to Gumroad. So, ah, here it is. You may notice the page count of the PDF appears about half of what’s listed at Amazon; as with the PDF of Game Boy World 1989 XL, I put this digital edition together as 2-up spreads, because the book looks much better that way. Hopefully this will not cause any troubles.
As usual, the addition of the latest volume to my Gumroad shop means I’ve knocked the price down on some older books as well. Please to enjoy these digital editions.
