Review: Approve review/compile
Moste of the code is correct, we mave some "Upgrades" form 8bit to 32bit,
that where broken before but got unnoticed, but now they will become visible.
Please check my inline comments
Id really like to have some coverage tool that checks that this code is actually
tested. Still OK for me.
Will run some test now and try to play a game perhpas today.

Values of this calucation may have changed as the cast to uint8_t may have
limited the value to 256,
I took a closer look but got not clue what this is finally about, mmh.

Mhh, instead of protection against underflow, we now dow this we the next
statement.

a const was lost here?
