No.16137 Robbbert Senior Tester Feb 12, 2019, 23:33	The problem becomes more obvious if you run kof2001 then mslug3 - it will crash, revealing the fact that the decryption routines for kof2001 are still in effect. Strangely, the problem doesn't occur when using MAMEUI or ARCADE - only when using MAME's inbuilt UI or the Tab menu.
