I2CEEPROMWIN.c (Bus_Pirate-master/scripts/)

Hi guys.
In order to investigate a weird behavior in the I2C protocol while using HARDWARE mode (https://github.com/BusPirate/Bus_Pirate/issues/54), I built a new firmware for my Bus Pirate v3 (viewtopic.php?f=28&t=8498&start=60#p66716) starting from the latest repository (https://github.com/BusPirate/Bus_Pirate ... master.zip).
Inside the Bus_Pirate-master.zip archive, at the path \Bus_Pirate-master\scripts, there is a C source named I2CEEPROMWIN.c from which I built the executable for Windows.
Seems to me I2CEEPROMWIN.exe does not work as expected since always it fails while reading the starting address simply by omitting him and shifting up all the bytes towards the high putting in the end a dummy 0x00 value.
Here is an example.
This is the real content of the chip:

Also seems to me I2CEEPROMWIN.exe does not work while writing because although no alarm is displayed and indeed it is declared that everything is done successfully, actually the contents of the chip have not been altered in any way.
From the source (I2CEEPROMWIN.c) the syntax is this:

pc_serial [com?] [chip addr 0-8] [R/W] [file] (read len) (mem addr)

That it is not clear as it states that the address must be 2 bytes, while actually using

I2CEEPROMWIN.exe com3 0 R TEST 2048 0000
I2CEEPROMWIN.exe com3 0 W TEST 2048 0000

or

I2CEEPROMWIN.exe com3 0 R TEST 2048 00
I2CEEPROMWIN.exe com3 0 W TEST 2048 00

It does not make any difference for the result.
Maybe the fault it is due the syntax I use that is wrong, maybe it does not work anyway.
Is there somebody here who can explain the thing?
What it is wrong?

Thanks!

Be seeing you.
