If it was a DVD image that you burned onto a CD that alone will stop it working

Marvel Vs Capcom is a CD originally on the PS2 Capcom Vs SNK 2 is a DVD originally even if it is small

The structure of a CD vs a DVD is not the same, you can't burn a DVD image on to CD and expect it to work or vice versa without re structuring the contents first and even if you do there are some games that will still not work
