Spectranet emulator in a browser!

Post by desertkun »

https://speccytools.org/emu/?tnfs=tnfs.markround.com

A tool to feature TNFS resource to anyone outside spectranet community.

Limitations:
  • It requires a proxy (browsers don't do TCP/UDP) so I provided one. Should the proxy die (see source if you wondering how it works), let me know.
  • It cannot "listen" or "accept" (so only outgoing connections work)
  • It ignores IP settings and DNS queries go to 8.8.8.8
  • It doesn't preserve ROM state (refresh discards all changes)
It's based on jsspeccy3, source code is available here https://github.com/speccytools/jsspeccy3

I have a hyper nerdy bug report :D

The flash ID read sequence is ignored, and so returns the second byte of the flash page rather than 0x20 for a 29F010 (or B5/B6/B7 for a 39F0x0 as in the newest boards)

Is support for the 128 model planned?
You could do persistent Spectranet flash by base64 encoding the whole 128kB and stuffing it in HTML5 localStorage :lol:
