Mame cores broken on Nvidia Shield Portable

On my Nvidia Shield Portable Kitkat, both Mame 2000 and Mame 2003 cores crash when trying to load content. The Mame Git core works, but it is too slow for many games such as Outrunners.

Is there a workaround/fix?

is there a logcat?

logs attached first file ending in 35 is from mame2000 the other from mame2003

Never mind the cores work they only crash with orunners.zip content but other roms work
