Sorry, I said Motorola SREC format but it could be Intel HEX as
well, but the same reasoning applies either way...<br>

Where do you get 246kB for the hex file? Is that the size of the
file itself? <br>
In that case you can expect it to be a little more than double the
size of the actual code, because it's in Motorola S-REC format,
which has the whole code in ASCII hex, where you need two
characters for each byte of code.<br>
<br>
What you see underneath "dec" is the base 10 representation of the
code size. I see 130,328 bytes for the .exe and 122,573 for the
hex. This is the size you should be worried about for downloading
code into ROM, right? And the exe should just barely fit into
128kB (131072 bytes).<br>
<br>
I wonder if there is any issue with the lack of text and bss
sections when you convert to hex.. maybe somebody else will know
about that.<br>
