Two versions of SuperCHIP V1.0 technically exist #4

I was looking over source code included with David Winter's CHIP-8 emulator/interpreter for games that targeted SuperCHIP V1.0 as I recently created a test ROM to test for SuperCHIP V1.0 high resolution font loading behavior. One game called "Blinky" does target SuperCHIP V1.0 and use high resolution fonts. However, the opcode/instruction variant used is the same one used for SuperCHIP V1.1.

I thought I was seeing things until reading two very old posts by Erik Bryntse that are on the SuperCHIP V1.0 entry of the extensions list. It seems like the older one might very well be an older (original) build of SuperCHIP V1.0 he uploaded by accident and as a result brought upon another build of SuperCHIP V1.0 that included the same opcode as SuperCHIP V1.1 for loading high resolution fonts. Might be worth noting (with those posts provided as good sources) two versions of SuperCHIP V1.0 exist.
