There was a lot of hype when the Magic Sac was first released stating
(in big bold letters) that EPROMS would not work.  To the best of my
knowledge, this was and still is just that - hype.  I don't beleive
it is that easy to distinguish between ROMS and EPROMS with such simple
circuitry as exists in either the Magic Sac or the SPECTRE carts.
