If you downloaded a clone but didn't have the parent ROM, the game simply wouldn't show up in the list. There was no friendly GUI warning. You just saw a missing entry.
Trust me.
In the sprawling, chaotic world of arcade emulation, few version numbers carry the weight of 0.34 . mame 0.34 romset
This led to the infamous "MAME 0.34b" (Bleem! frontend) era, where users spent hours manually scanning DAT files to figure out which 128kb file they were missing to make Super Puzzle Fighter II Turbo run. Modern MAME (version 0.260+) is obsessed with accuracy . It emulates the exact clock speeds of the Z80 CPU and the analog properties of the CRT monitor.
However, the MAME 0.34 ROM set is a historical document. It represents the moment when a teenager in their bedroom could suddenly play Teenage Mutant Ninja Turtles for free, without needing a bucket of quarters. If you downloaded a clone but didn't have

It didn’t support CHD (Compressed Hard Disk) images, couldn’t emulate 3D polygonal games like Virtua Fighter , and choked on anything with a protection microcontroller.
