I was interested in finding out which processor the 9200T was using and (don't do this at home) removed the cover, only to be confronted by a well glued on heatsink

So how to go about it now (me thinks).

I tried a couple of Humax tools available on the 'net to copy from Humax->PC, with no luck

Then was pointed to a tool called 'FlashReader' by someone going by the name of CrazySat

Downloading the tool and setting the 9200T with a null-modem I tried to obtain the (I assumed) 2 meg flash...and after a while (pretty slow process these serial ports) I had a 2 meg dump of what looked like the flash data.

I used the Win32 version with "flashreader 2 115200 flash.raw 3 0x000000 0x200000"

At the very top of this dump was:
"Copyright (c) 2003 HUMAX EMMA2 BOOTER Ver0.1".
So, we have a board that uses the same processor as the Topfield 5800 (I think).

Having went this far, I then looked for the Humax .hdf file to try and uncompress and establish that it was a mips processor.

After a lot of trial&error I eventually found a method to uncompress the code that runs the 9200T and can confirm that it is mips big-endian...loaded at an offset (it seems to me) of 0x800b0000.

Within the code is this (as way of confirmation):

Code:
003CDF60 3700 0000 2573 0000 5047 5854 4620 312E 7...%s..PGXTF 1.
003CDF70 3030 2E30 3000 0000 2573 2025 7320 2825 00.00...%s %s (%

If this confused you...don't worry about it. It is only intended for geeks
...maybe just me talking to myself

Nice detective work! I kind of thought it HAD to be the Emma2 given the things it does (esp. the three card trick)

Could you post a link to the FlashReader download, please.

You'll find it on this page as FlashReader4Linux&Win32.
