OK, I've tested these on two different PCs with completely different hardware platforms and os's (XP with nForce and 98 with Intel BX). Same results on both.
Chemeleon 1: Doesn't work in xbox
I get the Blue LED flashes on scan, and Unknown Flash error on write. A "read" shows all my banks as Unknown, and the save creates a blank 256K bios file (ff's).
The MD5 codes on each bank are

Chameleon 2: Doesn't work in xbox.
I don't get the Blue LED flashes, ever. I get the same Unknown on every bank when I "read"...and it too creates a blank 256k bios file, but it doesn't get the same "Unknown Flash" error...it tries to write for a while (status = "Writing") then eventually says: "Error Writing Modul!" (not a typeo). Same on each bank. This chip also gets really hot, like its shorting somehow.

Anyway...I think they're fubar..so I'll be applying for RMA's soon no doubt. Hopefully the Unknown Flash error one is just a buggy app, but we'll find out soon I guess.
