I am experiencing problems with some of the ROMS, I get the following message
"World Cup 90" (wcup90).
Mechanical systems or systems which require artwork to operate are not supported.
"Strider 2 (Euro 991213)" (strider2).
This machine does not work and the emulation is not yet complete. There is nothing you can do to fix this problem except wait for the MAME developers to improve the emulation.
Not sure what I am doing wrong!
