Where 65,816 fits
Why 65,816 is special
It extends the 6502 to 16 bits while still running 6502 code, which let developers carry skills and tools forward. Backward compatibility as a commercial strategy shows up in game consoles as clearly as in PCs.

6 × 10,000 + 5 × 1,000 + 8 × 100 + 1 × 10 + 6 × 1 = 65,816. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Related numbers & connections
The 65816 extends the 6502 line to 16 bits while still running 6502 code, which is why Super Nintendo developers could carry forward the skills they had built on the Commodore.

why?
Strength 0.50, confidence "high".
Technology & computing
The 65816 runs 6502 code unchanged while offering 16-bit operation, so developers moving to the Super Nintendo kept their existing knowledge and tooling. The same reasoning kept x86 alive for fifty years.
