Here are all of the old style textboxes in the March Prototype of Sly 2. Those can be easily viewed with a memory viewer, but making the actual textboxes appear makes them much easier to read.
Most of them are still used in this build, but there's some of them that are leftovers from even earlier builds. As a result, they can give us some information on how the game was back then(eg the inventory, and the arrow).
