Summary	06734: ROMs return to "available" list when launching a Genesis game with "Hide romless" set to on.
Description	When you launch a Genesis game from the "unavailable" tab, all the romless sets return to the "available" list upon return to the UI.
Steps To Reproduce	Make sure "hide romless sets" option is on. Launch MAME. Click on the "Unavailable" tab. Note machines and sets shown. Double-click on "Genesis (USA, NTSC)" in the "Unavailable" folder, double-click on any software item. Press escape to return to the UI after the cartridge has run. Upon return to the interface, "Unavailable" is now empty, and "Genesis (USA, NTSC)" can be found in the "Available" folder. I am finding that it deposits the caret at a random folder. I have been returned to "Available," "Working," and "Unavailable."
Additional Information	Using Windows 10 Fall Creators, v1709, patch level 16299.19.

When launching a set from those machines, the machines stay "Unavailable" on return to the GUI. So far, only launching a Genesis (NTSC) software set repairs the "Unavailable" and "Available" folders.

If not, please do. It will make make them not 'hide' so they will show up. It is On be default as most people only wanted to see what they had romsets for. All romsets which do not require and unique romset, or are 100% clones of another and have no unique roms are now shown, including the machines you've mentioned. It doesn't check that you have software, it only checks the romsets required to start the emulation.

When I exit a game run through the UI for Genesis, it brought me back to Unavailable listing - right where I was before I launched the system and chose the softlist item to run. Can you duplicate this one in a completely clean install environment? I can't discount the fact that a stray setting in an .ini or .cfg file might be interfering with things.
No.14370 Zaghadka Tester Oct 30, 2017, 12:53	Tried a clean install. The behavior doesn't happen with a clean install on my end either. Clean install was: mame64.exe, a roms folder with "megadriv" in it, the hash directory, the plugins directory, and a "mame64 -cc" generated set of INI files. I'll have to see what it is about my particular install that causes the behavior. This will probably take a while, but I'll see if I can't pin it down. Incidentally, on a very minor note, Mega Drive (Europe, PAL) is what shows up in the available list when "hide romless" is set to on. This is marked as a clone, however. It might be better to mark that as the parent and Genesis (USA, NTSC) as a clone if that is the behavior going forward. Right now, Genesis (USA, NTSC) shows up as the parent in the UI.

When I replaced it with a clean file, the problem went away. I'm posting the ini file to see if it replicates on your end. If it does, I'll look through it setting by setting to see what's causing the problem. (I should note that I believe this file was probably generated by mameui64 at some point, so it is unlikely anyone else will get to the precise state I'm in with vanilla mame.)
