Thanks mate!!. Good disk of emulators. Have tried it and the bbc emu works great, but the c64 emu gives me a critical error always (lack of mem maybe?).
But anyway as you said, a must have for a 500er!!!.
P.D: What´s the correct settings for the screen in the mac emu?. The options screen is good, but when i launch the emu, the screen looks like misadjusted or like. I´m using a bare 512k a500 and ks 1.3.
The dos emu works good too.
