I think I've pinpointed the “culprit” ;)
By default, when creating the database, users are given the option to exclude certain games from the database to make it smaller and speed up overall processing.

This is particularly true for MultiGame (/Mini-Games) titles...which most ...

Have you thought about placing the BIOS files for these systems in the “roms” folder in MAME (the steps are outlined in the Emulator tab)?

I cannot find how to get the bezels/marquees - whatever they are called now - to show?


I'm guessing you're talking about the “My Arcade Room” theme!? All you have to do is specify the folder containing your marquees as the “Cover” folder for that theme.

As for the list of shortcut keys, you'll ...

This setting is now part of mGalaxy main application. The panel is named 'Controllers panel' and is called by the 'c' key by default!

Which version of mGalaxy and which version of Mame, please?

Hi Rob,

It’s true that my main job has been taking up a lot of my time lately… but I’m still working on mGalaxy, just so you know!
The thing is, maybe I shouldn’t have worked on three new themes at the same time… but rather released updates after each new theme ;)

When creating the database for MAME, mGalaxy expects to find (in the MAME executable folder that has been specified)

No, it's not included in the “Arcade” themes (btw, are you using 'Arcade' or 'Arcade Room' theme?)... but I can make you a beta version where it will be (and then integrate it into mGalaxy permanently).

If you are upgrading from an older version, simply reinstall the new version in the same folder...and when you start it up for the first time, an update will be performed! (As a precaution, first test it on a copy of the folder from the older version!)

If you no longer have the “old version ...

'Favorites' (as well as 'Tagged') info have been moved to the system database file (xmlout.xml).

Disney,

Unfortunately, the list is too long for me to look at each system individually.
However, the fact that you tell me that some systems are not original in mGalaxy, or that you have copied and pasted data between versions, makes me understand what must be happening.
There have been updates to ...

Rob,
Would you please list the systems and emulators that you can't get working and explain the symptoms ?

OK, mGalaxy is minimized in the taskbar...but if you maximize it, does it respond? I mean, can you browse the games list, for example?
