ok, i will investigate sfc further
btw. sfzch is in Kawaks and MESS if that lends it any legitiamacy,
(and MAME32 plus (i know that doesn't mean much, but i thought i'd stick it in because it represents a driver source)),
sfach (the clone) was not classed as a game (although it is) it was a "Publicity demo"
shown running the attract loop in stores and such, but never released for sale in the US apparently,
it's also rather rare (1 512KB rom) pm me if you need any further info
these games had something to do with Raz creating some of the first XOR tables for CPS2
because they contain unencrypted data which is the same as the encrypted data in the CPS2 version of the same game (
link).
so if nothing else they're kinda interesting in a emulation history type way.
but your right, its not a priority, just interesting...
(pauses to consider all the great CPS1 games in the current MAME driver)
oh yeah !
