Exist a setting to show/hide tabs ?
As example, I no need the "Flyer" tab.

Yes. Go to the setup dialog ("Tools" -> "Options..." in the menu). On the Front end / GUI page there's a (big) "Detail Setup..." button. Click it and (de)activate / order the details as you like!

Ups, not seen yet. My mistake ...

Thanks

All tab-widgets in the main GUI also have context menus to let you choose the placement / orientation of the tab headers (but it may be hard to find the valid area for that context menu -- point the mouse directly above the header text and do a right-click).

The context menu of the "details tab" (upper right corner in the default configuration, see below) includes a "Setup..." item which will also open the detail setup as mentioned above.

BTW, the tab-widgets of the main GUI can also be "swapped" and the orientation of their splitter-layouts can be "flipped" (part of the splitters' context menus). I mention it because it may not be obvious ...

This I call hidden feature.

My last question at moment.
Is it possible to mount/load a software by using the frontend (the devices tab and its functions is not clear for me) like the device view function on MESSUI ?
Not sure it is already integrated or coming soon.

I´m not talking about the software list support which is not fully working.

r2674

If the "Devices" tab is selected and I exit QMC2 I get a crash on WinXP Pro SP3 32-bit.
With the other (selected) tabs does not arise this problem.

Heh, nice screen shot. This UI looks good, I hope you will find the courage to maintain it in the long run. At this rate, we might need your front end soon enough.

Thanks, MESSfan -- I try to keep up with the MAME and MESS devs, but it's not always a simple task. Anyway, QMC2 is around for a long time already, and I plan to keep it that way...

@Anna: thanks for the report and screen shot! It's likely a bug... I have to check. And yes, the "Devices" tab is supposed to do the job you want to achieve. There was a bug prior to SVN r2670 (see http://sourceforge.net/apps/mantisbt/qmc2/view.php?id=17), but it should work again now (with the build you're using).

What you have to do:

0) optional/recommended: click the "Configuration" button and select "Default device directory for '<machine-name>'..." so you can point QMC2 to a "primary" directory where you have your cart/rom/bin/whatever files for the current system (machine in "QMC2 jargon"). This directory will later be presented to you when you "browse" those files...

EDIT: note that the second item - "Generate configurations for '<machine-name>'..." - is a not yet implemented WIP feature.

1) click the only "enabled" button right to the device name ("No devices") to create a new empty device setup

1a) if you're going to use device files with speaking names, don't bother with setting up a name for the configuration... QMC2 will automatically do it for you -- see 2)!

2) from the (then enabled) list of available "Device instances" select the one (or more) you want to map a file to; when you click the browse button, the default directory from 0) will be used, filtered by the names that fit the "Extensions" column.

3) When you've selected a file this way, QMC2 will suggest a configuration name (when the name is still not set, that is).

4) When you're done with the setup, click the "save" button (right-most tool button, now enabled as well!)

5) The configuration will be added to the list of "Available device configurations" and can then be selected and "played"

@Anna: yeah, I get that on Linux, too:
