Here's Python code. It works for both my 880 firmwares. I'll work up C
for inclusion in libharmony soon; need sleep!
bstr = '\x48\x47' + bstr[6:]
sumb = 0x43
suma = 0x21
for i in range(0, len(bstr), 2):
a = ord(bstr[i])
b = ord(bstr[i + 1])
suma ^= a
sumb ^= b
print "%02x %02x" % (suma, sumb)
Yeah, it's damn simple; just takes ages finding it in 64K of safe mode
firmware!
