Thank you very much

Hi there,

this is just a guess cause I'm using Retroarch for VIC20 and do not have much experience on this system. But from your games listed I played "Demon Attack" without any problems.
Your screenshots show that you have lots of Expanded Memory activated. Did you try with some different setups? As far as I tried it, the VIC20 tends to have some problems on some games when there is too much RAM recognized.
According to this website "Demon Attack" runs on an unexpanded VIC20.
Maybe you want to give this a try?

thansk, i tried as you suggested and i tried with all the different ram blocks combination, but i always have same error... i tried the others games with different ram settings, but i always have same error...:(

 

Anyone know how to fix it?

thank you!
