Didn't find any other threads about this.

Early this morning, however, we were greeted with an anonymous email containing a screenshot of the ‘SuperDisc’ BIOS screen and a link to download a file named SDBR_v0.95.sfc.
Following this we opened the ROM up in a hex editor. Although not expecting to find much, there was some descriptive content - namely a reference from a developer who worked on the project at Sony: Tomomi Abe.
Futher helping its fight for being the real deal, we're pleased to report that the boot ROM works on the original hardware through an Everdrive flash cartridge (as shown above), but not the more powerful SD2SNES.
I've never heard of Retro Collect before; the article simply popped up on Reddit and wondered what Gaf thought of it.
I'm leaning on whether this is real or not, but stranger discoveries have happened before with the Nintendo PlayStation.
