I don't think frying effects depend on RAM contents.
I've never dissassembled Space Invaders, but I've never
seen any classic game at all that doesn't completely
clear the zeropage on startup.
If you'd ask me, I'd say that the only possibillity for
the frying effect would be a misreading of the FFFC/D
vector on start-up and/or missetting the PC on the
booting-sequence of the VCS.
