No idea. It was doing exactly the same thing for me in 1.666 but I found the problem in the driver and fixed it in 1.7; now it works as it should.
as i said not bothered but i do luv a mystery why do you think this is happening +T+
I'd suggest not altering the ROMset in any way then maybe try it with a completely clean install of the emulator.
yeah i got fantasy zone 2 working and yeah it was a rom issue,nothing you havent heard before lol..
what a great update from the master system/arcade game of fantasy zone 2 thanks for this also i see that you added shinfz.zip which is basically a korean bootleg with shinobi and fantasy zone 2 as well.
just so you know when you play rtype 2 the music starts fine but if you lose a life then the music will either go off or you sometimes get a load of blips and beeps.
you probably know this already but just thought i would let you know.
