I added a check in start up for Golden Five (and extendable to other games) where certain start up RAM values break the game.
The check looks in the GameDBinfo, so any game requiring this check will need to be added to the game DB.
Should finally fix Golden Five
This is a long way from functional, but at least now the game will boot.
It needs the keyboard to do anything (so it's in a similar state to compumate on A2600)
Fixes Little Ninja Bros and Corvette ZR1 Challenge
Still needs investigation as seqeunce is 3,3,3,4,3 when it should be 3,3,3,3,4 but need a new test case.
Also added a note about DMA timing that needs to be investigated next.
