q1) The way how invaders sample clones are handled has been changed. You can't compare a .119 datfile scan with a .119 mame import scan when you've updated to cmpro 3.106c. Background: MAME exports several invaders sample clones while invaders doesn't use samples anymore. Earlier cmpro versions corrected them to use their own sampleset, latest allows not-existing sampleof parents.

Old MAME versions are obsolete. There is no need to use anything besides the most current MAME.
