Found a temp workaround to get Mala to import 108u4 xml without the SaveBiosList bug.
this is working 100% on mame 108u4
1.output the xml file from mame eg. mame -listxml > 108u4.xml
2.edit the xml file with notepad & find the line "<mame build="0.108u4 (Sep 15 2006)">" (no quotes)
3.change the line to "<mame build="0.108 (Sep 15 2006)">"
(no quotes)
4.refresh the game list
Thats it!
hope this helps
Big thanks to swindus for all his hard work
