Summary	08348: gba [pacmancl, pacmanclu]: Game crashes after title screen

Steps To Reproduce	Just press Start at the title screen.
Additional Information	Research points to August 15, 2016 as the regression day. Primary culprit seems to be: https://github.com/mamedev/mame/pull/1244 https://github.com/mamedev/mame/commit/9ec0c60147662085a23914e01966823e73c21f5a

Most bugs are obvious bugs but the flag is only when there is a debate of whether or not a bug actually happens on original hardware or not.

Fortunately, there is only about a week worth of source changes to critique and there is is some ARM7 action among them which is likely the cause. (January 8, 2012 - January 15, 2012)
