You should never really mess with the xml files, there is no reason to do so. Also there is a change rom path option in the UI.

Reinstalling does NOT remove your systems and games. You have installed to the wrong location, likely inside of the Launchbox folder, so you likely now have a Launchbox/Launchbox folder, and you are launching the new one which has not been setup.

Hold the windows key on your keyboard and use the printscreen button, this will save nice high res images to your pictures/screenshots folder.

That sounds like the Retroarch message, not Launchbox. So you need to check your Retroarch details, the API and such in Launchbox is only for the Launchbox UI, the actual emulator still needs to be logged in as well.

Thats the nature of retroarch due to it having a overhead compared to a standalone emulator, as it has the whole UI running in the background while running games. It will also depend on system specs of course, throwing more power at the situation may make it fine in Retroarch as well. So a standalone will always have better performance, but that doesnt matter at all in 99% of cases as the emus generally are so easy to run. I dont mess with 3DS emulation too much as i just use a hacked New 2DS XL, for that, but its still a fairly new emulator and lots of games still have issues, so its not a perfect experience in either case. Retroarch does add support for a stylus on the right stick as well as on the fly changing of how its displayed via controller hotkeys if thats something you want.

You dont need to delete anything, just run the importer again to update.

The license is yours to use on as many of your PC's as you want. Easy way to tell is fire up Launchbox and does it have your license name at the top right of the window? As for the AV, disabling it may not be enough as it may already be quarantined, you would have to tell the actual AV to release that file.

Easiest way would be to close launchbox and delete the cache from Launchbox/Images/Cache-LB. Otherwise you will need to do it per platform by highlighting the games and hitting F5.

Yes, it will just update the existing files with the newer info.

You can just rerun the MAME importer pointing to the new location. Id uncheck all the media downloads and fill the new missing stuff in after the import to save a ton of time.

Its used to invoke the Launchbox pause screen, as MAME itself usually has full control of the keyboard, this allows the keyboard to actually work as a PC keyboard rather that what MAME is using it for. So you may find that pause screens dont work correctly for you now for MAME.

That wont help as its not Launchbox itself that is having the issue, its files written since the install. If you dont have a backup of the input.xml then you will just have to delete the one you have with Launchbox closed and let it re-create it on next Launch. This sounds like Launchbox was force closed, or your PC was shutdown while Launchbox was still writing to files after a exit.

Thats clearly a image of the FTP above, not the site. So you will need to get them there.

Correct, steam is the DRM and needs to be running when playing Steam games. Even when you launch a game directly from the Steam folder, it will still launch Steam first.

They will still need Steam running though.

It depends on the settings you use, as well as the region you specify, but i have 2852 imported.

need a tissue?

lol, nice catches i guess.

Agreed, partly.

when you say beat em up are you talking a side scroller like Final Fight, or a 1 on 1 like street fighter?

Launchbox doesnt care what version you have. It could be the default commandline though as its such a old version, you may need to remove the line in the below image.

Tools/Options/Updates, enable betas then restart Launchbox.

In fact all cores in that image say they are missing, have you actually downloaded any cores from within the Retroarch UI?
