I am curious by nature, what is the method of calculation? I try to do it myself but I did not find it.

Indeed, I noticed that the km is recorded in the first two lines, but I did not understand how to calculate the km.

Is there a multiplier or something else?

He is furious not to understand, I would like to sleep less ideot tonight, lol ;)

Hello,

I still do not understand! Should it invert the XOR and multiply it by 16?

[nikz]

yes, this good.......

Yes. Bytes seems to be swapped. Looking at the original dump: toDec( F5E2 xor FFFF ) * 16 = 41424 (close enough)

Or to get the new km.

toHex( 40500 / 16 ) xor FFFF = F61C
