MAME Sanity Check

[BabyBillyFreeman]

hey everyone, started my journey into LB and retro gaming in general in June and have become a total addict, building arcades, etc.

 

Anyways, I just wanted to post something here to get a sanity check real quick, since my mind can't make sense of this; I'll summarize quickly below:

- I setup MAME 0.246 in LB like usual; LB auto sets up all the following emulator settings for me:


- If I launch a game through LB; it simply won't launch. I discovered that if I remove the following command line option ("-rompath %romlocation%" this is added automatically by LB), everything works fine again, etc.

 

My question is- is this normal? Why would that option cause issues? Important, but I place my MAME rom sets/files in another location (i.e. ../Launchbox/Games/MAME_ROMs)

Notes:
- Games launch/run fine through MAME outside of LB
- Games launch/run fine through LB if I remove that command line option -rompath %romlocation%

Thanks for any info that can help e understand the cause for this; I'm sure I'm doing something wrong that LB doesn't like!

If your MAME fullset v0.246 ROMS are located in the "..\LaunchBox\Games\MAME_Roms\" folder, and if you can start standalone MAME, select a game and run it without issues, then you've already setup the rompath in MAME.  Either by editing mame.ini, or setting it up through MAMEs configuration menu.  So far so good?

If in LaunchBox you edit, say, 1942, in the Launching section under ROM File, it should look like

(Note: shown is a relative path. Which it will be if it's on the same Drive: letter as LaunchBox. When supplied through %romlocation%, it will be an "absolute\path\in\quotes".)

I'm curious where your MAME ROMs are actually located (vs an example folder) and how that compares with what's shown under one of your games' ROM File.
