Watch On See some hands-on Super ZSNES footage and discussion from MVG, above. The RetroTuber has had access to this emulator reboot for a couple of weeks.

Before deciding to go ahead with this project, zsKnight had pondered what to do differently for a reboot. The dev told MVG, “I had to brainstorm a bit, thinking what I could do differently. So, I started out by writing a GPU renderer that replaces a large chunk of the SNES PPU emulation with rendering done mostly on the GPU through shaders.”

In the first release of Super ZSNES, MVG confirms tasks such as “palette lookups, tile rendering, transparencies, mode 7, color math, main and subscreen combinations, mosaic effects are all handled via GPU shaders.” This architecture unlocks some ‘Super’ enhancements in the new UI, and some intriguing possibilities for coming releases – like high-res textures, for example.

Another aspect of this new emulator that makes it 'Super' is its new Super Enhancement Engine, and it is here that we reckon the new GPU-powered architecture will also often come into play. We’ve tabulated what this means to your old SNES games, below.
