Summary	08418: all with a secondary optional BIOS: MAME should not prevent running a system if a BIOS that is not selected is not present.
Description	An error should be thrown a the time the BIOS is actually attempting to load. Missing additional BIOS ROMs should not prevent a system from running if they are not needed.
Steps To Reproduce	Attempt to run any system with alternate BIOS ROMs with any of the alternate ROMs not resent.
Additional Information	Saying this is too hard to fix or saying this is how it works is NOT a reason to mark this issue as invalid. I would suggest throwing an error at the time MAME actually attempts to load the ROM, not when the emulation is launched. Saying "oh, just launch it from the command line" is NOT answer, as that simply makes the user interface pointless. If you are going to have a GUI, then support it and make it work PROPERLY.

The aggressive nature of your post is not welcome here.
