Does this change if using ROM 2.0? I believe later coverdisks used FFS and I know for certain my copy of Deluxe Galaga only works with the 2.04 ROM because I put it on a FFS formatted floppy. (as I owned an A600 there was no reason not to)

So the question is, does 2.0 use more RAM than 1.3 and so in turn would it actually be useful to have 1MB chip?

Its kinda mute at the moment anyway, Mr Nutz is still crashing on rc2-4 but worked fine on rc1, so there are more important issues to deal with right now I suspect than RAM allocation.
