Gamulator is probably one of the most used ROM websites in recent times to download the best working roms. The interface of their website is really simple and helps you find the game you are looking for even if you do not know the complete name of it. It is safe to download as you have no virus threat. They provide you the option to download the game directly or through a download manager.

Yes, it should work fine to have both in the same folder. BUT it's most important that they are the same version.

Simple, for example savestates can fail or nvram can get corrupted. But your computer won't explode anyway...

I'm the same, there is no way to find the missing ones, I have partial ones, the Double Dragon and the Michael Jackson. Does anyone have them complete?

  You can but, keep in mind both exes share some directories like nvram, cfg, ini and sta. Those files will be overwritten by the last exe used, and the results could be unexpected or undesired.  Why?   If I play game X on mameui and then the same game on mame why would I want settings or saves separate?

I've changed all the controller mappings to mouse. The only advice I've found says to do that, like it solves anything.   The [tab] config menu lists mouse as a choice for x and y analog.   But mouse has no effect in the game, area 51 for example, and you can't set mouse or mouse buttons for anything.   Any ideas?
