Super Nintendo Entertainment System
Operating Systems (Ricoh 5A22, alt. WDC 65816)
Console emulation (potential)
Whether these emulators support operating systems for these consoles is unknown; it must be looked into further. Consoles without meaningful OSes are not included.
Nintendo Entertainment System – Project Nested

SNES-OS
High level Linux-like OS Running on a SNES. The OS is intended to be used with a custom cart with the bios and other requirements. The exact requirements are not known at this time. Minor Modifications to the SNES Hardware may be necessary.
No emulator support.

Super Famicom DOS
what looks to be a compiled version of it (dos.hex) and it does seem to run in an emulator (after being converted to a binary).
Official Nintendo-crafted DOS clone, found in the July ‘20 files leak. Look in “other\SFC\SFC_50SEC~3_YK3YV~S_67V3K~2\tool\” sfxdos folder.

Satellaview
The info for this is quite widely known, and it doesn’t exactly fit the “web browsing”, but it’s close.
Version & Revision Guide
For general information, see the Game Console Revisions Overview.
Versions
There are two versions of this console, arranged chronologically.
“SNS-001 (original)” (1991-1997)
RECOMMENDED OVERALL; LOWEST PRICE; BEST RELIABILITY
The model of the SNES that everyone recognizes. Blocky form factor, horizontal purple slide-up buttons, and oftentimes, yellow plastic. Furthermore, the gray area between the two purple sliders, is actually a cartridge eject button! These consoles are common, and have the superior function, as long as you get a 1CHIP (later era 001s), which have much better video output. On the bottom is the smallish EXT port, mostly unused in North America, but used elsewhere for Satellaview. To the back, is the first usage of the Multi Out port, plus RF and a power adapter.
“SNS-101 (Mini/New-Style)” (1997-1999)
Despite being a lower cost revision, these are actually quite uncommon in North America. They’re also very easy to recognize, being smaller, rounder, and replacing the distinctive rectangle purple sliders with vertical and circular sliders. Furthermore, the Multi Out port does not support S-Video or crucially, RGB. There is also no RF out, nor is there an EXT port on the bottom. In fact, they even removed the cartridge eject button… However, they do have better video quality than most SNS-001s, assuming that you mod it to support RGB. Also, the plastic doesn’t yellow. This has only one board revision, which is basically a 1CHIP that needs modding for RGB.
Revisions
There are 4 revisions within the SNS-001, and no revisions within the SNS-101.
SNS-001 (original) revisions:
Distinguishing 001 revisions can be quite difficult w/o disassembly, except for distinguishing between a 2CHIP and a 1CHIP. Luckily, that’s the only distinction that really matters here.
“SHVC-CPU-01” (1990-1992)
DO NOT PURCHASE
Likely the absolute worst SNES one can buy. These have all the poor video quality of a 2CHIP, and are even prone to CPU/PPU faults and malfunctions, at a rate which is worsening over time. The only positive these have going for them, is that there’s a very slim chance that the video quality is vaguely better than other 2CHIPs.
“SNS-CPU-GPM/RGB-01&02” (1992-1995)
LOWEST PRICE
These revisions do not have the CPU faults found in the CPU-01, but otherwise, nothing has changed. Poor video output that may be a touch worse than the CPU-01, but at least the video doesn’t “clip” like the 1CHIPs.
“SNS-CPU-APU-01” (1995)
Some anecdotal reports say these have a video quality similar to a proper 1CHIP. However, most others disagree and say these have particularly poor output. Likely not worth the gamble, so take them as being bad like the GPM and RGB. It appears that the first UN31 serial numbers may have been granted to these revisions, but are most likely found in 1CHIPs 99% of the time.
“SNS-CPU-1CHIP-01 to 03” (1995-1997)
RECOMMENDED OVERALl; BEST RELIABILITY
The absolute best of all the classic SNES revisions. Superior video output, still has RGB out, the extension port, and so on. These consoles do output slightly bright and with supposed “ghosting”, but these are VERY easily fixed. Guaranteeing if a console is a 1CHIP requires opening it, looking on the motherboard for the term 1CHIP. However, one can read the serial number to increase one’s chances, as it appears that every 1CHIP has a serial beginning with UN3. However, not every UN3 is a 1CHIP. Some believe that UN31 is the number where 1CHIPs were introduced, but as seen below, some APU-01s can have a serial starting with UN31.
