If there are 200 missing games why not go look for them yourself like everyone else does ? That's what Google is for after all. Just a thought ?

yes, i have done all this. no artwork as neil9000 mentioned renaming to Arcade instead of MAME.

Yes, i have literally tried everything you mentioned and more. I have now tried running it on Windows 10 Home & Pro 64bit with latest updates and it still won't load. All settings are correct. As i mentioned it works fine through RocketLauncher and MAME runs perfectly using Hyperspin so it must be something to to with Launchbox I even tried earlier Launchbox and its not loading either. I have been using emulators for many years and I hope I know what I am doing, but for me no MAME emulator works. i will just run it through RL instead for now.

The only difference we seem to have is that i am using a MAME nonag emulator, you are using official MAME. Also you use Arcade, i use MAME as platform name. Also running on Windows 10 Pro 64bit (version 1803) PS, I have Just installing a fresh Launchbox, setup Arcade with full MAME set option using MAME 0.210 FULL SET + CHDS and emulator still won't load (all anti virus etc off) This works completely fine on my setup, using Hyperspin or RocketLauncher, or MAME emulator itself, just not Launchbox or Bigbox Tested with RetroArch and it loads perfectly on this setup, just NOT MAME emulators, any of them nonag or official.

ok, i will take a look. Thanks again

MAME working using RL. snsLaqQb297crpQGD7oca7f651CIy1KrUNjsOAlK.mp4

Yes

Here is the issue, FYI K653rRzXZhLPBOfTF1ZWdIfGoB8dPwfdCb13WeKk.mp4

no, still same. I think I will stick with RL for now. Maybe you will see an issue going forward or it's just me. Thanks anyway for your help

rename to what ?

both, you do mean the MAME.ini for the emulator itself ?

yes it's also correct.

I have also tried removing command line and still same issue

yes, all is correct. I have been using it for a long time. I thought I would try using Launchbox settings/emulator instead of RL and many systems run ok just not MAME. I have seen others also mentioning it on forums.

hi, yes they are

no i am using MAME, i was just mentioning that RL works as an alternative

I am using MAME 0.210 romset and games load fine from MAME and when I use Rocketlauncher, just not when using Launchbox,BigBox with emulator settings. If i run it through my RL setup it loads fine. Used to work fine before latest update, now just tries to open then closes. Thanks

Same here for MAME 0.210 on latest version Beta release of Launchbox Running on Windows 10 64bit

yes, but make sure it's for MAME 0.210 set.

Hi, sorry i remembered that and deleted it i thought. Thanks for doing it if it was still there.

you need to update bios files to 0.210 also one of those files is neogeo.zip, that is required to run neo geo games.

Bios file removed
