This includes, but is not limited to, video changes (more to do) as well as discrete sound filtering additions (more to do). Combine all that together core, memory and other issues that keep the emulation going and that only means one thing.. your ATHLON 1.2gz Thunderbird (which you yourself termed as an "old pc" above) is too slow now to run current MAME for that game. If you must use that machine, you have to use an older version more suited to it. Expecting a decade+ old processor to play the same things with versions of MAME that were released nearly 4 years apart is not logical and is not grounds for submitting a bug report. Closing.
