Emulator developer byuu demonstrates how DerKoun's HD Mode 7 SNES emulation works


Earlier this year, we saw the release of a fork of the bsnes emulator, which thanks to the efforts of DerKoun, allowed for HD upscaling of Mode 7 assets in Super Nintendo games. A few months later, the ability to emulate SNES games in widescreen would also be added, along with supersampling modes that could go up to 10x the original resolution. Eventually, byuu, developer of bsnes, decided to officially incorporate these additions into future builds of his emulator, with further betas of the bsnes-hd emulator offering slight bugfixes and improvements. For many, these phrases and ideas can be a little hard to understand, so byuu has decided to upload a YouTube video demonstrating the changes and improvements that the HD Mode 7 feature adds, while also explaining what some of these terms mean, and do for the end user. If you're interested, you can check out the 9-minute video, linked above.

In this video I demonstrate the recent HD mode 7 functionality in bsnes, which is courtesy of DerKoun. While explaining the origin of the feature and how it works, I demonstrate the effect in real-time in Pilotwings, The Legend of Zelda: A Link to the Past, and Dragon Quest III. I then walk through an explanation of how to use the various HD mode 7 settings present in bsnes.

Need a Epyc 7742 or Epyc 7H12 for this bitch. This is a CPU destroyer. But, it's absolutely incredible how much the different is in resolution.

You mean that a tweaked snes emulator is more demanding than a wii u emulator? Oo

I would think that Dolphin is more optimized than this particular effect as it stands now. I'm sure in a few months, maybe a year, it will be much less demanding. I dunno, I could be wrong though, but this is new stuff, and generally it improves with time.

This is phenominal. I prefer to use Emulators over Consoles just because these days the native resolutions of older consoles strains my eyes. (I'm getting old, 28 tomorrow...)

Anyway, I can't see this being incredibly demanding for modern hardware. I mean, PS1 recommended hardware is a joke by todays standards even for an entry level PC or Laptop. ePSXe's Recommended specs are only 1GHz processor and 512Mb of RAM :rofl2: SEE HERE

It probably takes a little more processing power for this application shown on bsnes, but I can't see you having to break the bank in order to get the feature working.

Bsnes/higan/whatever is an actual (low level) emulator that goes for accuracy first (which actually makes me very skeptical of upscaling, meaning less accuracy with respect to graphical output), Dolphin by default is an HLE which is more about "running GC/Wii software" than "replicating the system and its accessories" even though obviously it has to do some of the latter, but with more liberties taken

Dolphin is GC/Wii. Wii U is something like Cemu
