Hacking SDK version ?

[arfgh]

is there a way to know the used SDK to compile the game update we want to mess up ?
i have seen that some updates for 7.02 can be installed in 6.72 because it seems that the used SDK to compile it was just 6.72 precissely.
So is there a tool or a way to reveal that info ?

thx in advance

I made a simple Bash script that reveals both SDK and required firmware: github com hippie68 fw
I can't post links yet, so replace the space with dots.

If SDK is lower or equal than your firmware, you can theoretically play, but also:
If FW is higher than your firmware, you might need to spoof.
