[What do I need to download for mame .251 complete set?]

Your merged set has more-than-enough games (ROMs) that can be played.  

Some of those ROMs require a CHD (Compressed Hunks of Data [yes, that's the actual name]) file as well.  For simplicity, think of a CHD as a CD 'game disc'.  There are about 660 CHD's.  Excluding clones (Japan version, US version etc.), there are 371.  Of those 371, only 58 are considered "Working" in MAME.  (note, some of the non-working CHD's may work with other emulators. But don't count on that being the case)

If HDD space is not an issue, just place all the CHD folders in the same directory your ROMs are located and you should be good to go.

An example of a game that requires a CHD is Area 51.  

../Games/Arcade/area51.zip
../Games/Arcade/area51/area51.chd

 

Use the Arcade Full Set Import Wizard tool to import them.  When you get to the filter section, if you decide to not use games that require CHD, you can check the option to exclude those. Note the 1st checkbox  option will skip the games unplayable in MAME.  So for the ones requiring CHD's, it'll whittle down what's imported into LaunchBox to those approx. 58 (plus all the working arcade games that don't require CHD's).

 

Note that LaunchBox doesn't touch your ROMs at all during the import process.  So if your Games folder has 40,000 ROMs and after import you have 14,000 games in LaunchBox (depending on your selected filters), you'll still have the full 40,000 ROMs in that folder.

[Feature request: Multiple games delete]

Oh krikey!!  I need to pay closer attention that there are Android sections on the forms.  My apologies. 

[Daphne window not active when run from BigBox]

May be a shot in the dark.... try creating a shortcut to the batch file.  Right-click the shortcut and select Properties.  Change Run to minimized.  Click OK to save.  In LaunchBox, change the path to point to the shortcut instead of the original batch file.

[NES Super Mario Bros. Retroachievements glitch]

Check how your games Title is named compared to how it is on the Retroachievements site.

[Feature request: Multiple games delete]

When you select a single game, you can then hold the Ctrl key, click on other games to select multiple games.  When you have a few, several or a bunch selected, click the Delete button at the bottom of the screen to delete them all at once.

As for the multiple popups during the deletion process, there's no getting passed that built-in 'safety feature'.

[Mame_UI/Flip disk - Using retroarch with mame core (Apple II)]

If Retroarch-MAME (vs standalone MAME) has a mame.ini somewhere, as stated you should be able to set ui_active to 1 (1=on, 0=off).  In standalone MAME's mame.ini, it's located under the CORE INPUT OPTIONS.

#
# CORE INPUT OPTIONS
#
ui_active  1

 

Alternatively, if the RA MAME core acts like standalone MAME, you can press Scroll-Lock [key] to toggle the emulated keyboard during emulation.

i.e.  Press Scroll-Lock, then you can press Tab to access the MAME menu.

im getting an error that says "failed feedback lever initialize" how do you get passed that?

2 solutions

1)  enable force feedback option with -force-feedback in cmd line (or ForceFeedback = 1 in Supermodel.ini)
2)  enter service menu->game assignments->feedback lever = disable
 

[Where are the small category icons located?]

Where do we tell LB what icons to use, or does it just automatically figure it out for itself?

If you name it the [exact] same as your Platform (Platform Category, etc.), it'll just automatically figure it out for itself.

The one's in the Details pane are in \LaunchBox\Images\Platform\  And it too will 'just automatically figure it out for itself' if you copy an image file (vs. icon file) into it.

how do you exit out? usually i just hit start and select on my controller, but thats not working.

Make sure you have it still mapped in LaunchBox.  Tools, Options, Game Controllers, Mappings.  Note that LB and BigBox are mapped individually.

Also, make sure your controller is on prior to starting Dolphin.

yes, see my screen shot above.

That's for your emulator.  Can you edit the game and show a screen shot of the Launching section and another of the Emulation section?

The error is saying Dolphin.exe, but your emulator is is pointing to DolphinWX.exe.  Is your game pointing to the correct version of Dolphin?

["Bulk Run Before/After Main Application"]

I see that the "Bulk Run Before/After Main Application" has been removed and "Add" replaced it.

Those names are the same thing.  I think I renamed it at some point to make it clearer, thus making it more confusing. 😊

The plugin is the same and still works the same.  The plugin to download is called "(Bulk) Add Additional Applications".  But when you right click your selected games, the option (plugin) to select is titled "Bulk Run Before/After Main Application".

I've tried going into Tools, Add, under Metadata...Additional Apps...Add apps.

You lost me at "Tools, Add".  Sound like the process you're doing was attempting to add a new game.

Do you have the newest DLC wave 3 and version 2.2.1? Because what's in your screenshot is V0.

I guess I don't.  But it's also the only Switch game I have on my system. Plus, it seems to run.  At least for the little that I've played it. 

[Launchbox not responding to any keyboard keys except pause, fastfoward, and escape to exit. Any ideas? Cheers]

It's not a LaunchBox thing.  What emulator are you using?

If it's MAME, press the Tab key, then try your other keys.

[problem launching switch games with yuzu]

Not sure if it helps any, but this is working for me...

[Philips CD-i games not launching]

Glad it works.  As far as 'cheating' and getting passed the initial screen and directly into the game, I don't believe there is a way.  But hey, this is what gives you that authentic feeling of when you played CD-i as a kid.  

[Can the checkbox "Remove file extension and folder path" in the Edit Emulator screen details tab could be separated into two separate check boxes.]

Appending the .ext was my 1st thought.   

 

1 hour ago, rye74 said:

I don't know if its thats something the devs would wanna change that though.

The best way to set this in motion is to create a bitbucket request.  At the top of this page click HELP & SUPPORT and then REQUEST A FEATURE.  Once completed, add a link to it here to gain exposure and get upvotes.

 

In the interim, you can always create a 2nd batch file for your other 'emulators' that [would] use the same batch file and use %1.  

Or get super crazy and add a Default Command-Line Parameter for the different emulators using the same batch file.  Example "path", "file", "fileExt".  Then in the batch file, add

if %1==path (set param=%2)
if %1==fileExt (set param=%~nx2)
if %1==file (set param=%~n2)
echo %param%

I've run into a situation where i want to pass the filename and ext but no path and I can't seem to do it because the way its setup, Please let me know if this is feasible or if there is another way I could accomplish what I'm trying to do.

If your case use is passing it to a batch file, in the batch file you use %1 to reference the full parameter.  Instead, UNCHECK the "Remove file ext..." and in the batch file use %~nx1 in place of %1.  This will result in just the fileName.ext.

 

To test, create a batch (test.bat) with the following:

@echo off
echo %1
echo %~nx1
pause

Drag and drop any file onto "test.bat".  The resulting Command Prompt will display the full path to the file on the 1st line and just the fileName.ext on the 2nd line.
