I find the new Lua plugin for hi scores works fine. I don't think you'll get much of a performance boost from compiling your own MAME. From the MAME Wiki page:

Your post caused me to re-look and obviously it worked from the command line as I had forgot to add the -f option. I must be tired, as even though I quoted your post about the options order, somehow I still had -g -f. All working now, thanks.

I'm having the same issue using Cemu 1.6.3 If I start Cemu directly and than load the game, works fine. If I start the game from the command line using Cemu.exe -g "C:\WUP-P-ARDE\data\code\RedCarpet.rpx" the game loads and starts fine also. Whenever I use Launchbox (with or without the -g command option), I get the "Unable to open file" error from Cemu. Any suggestions? Edit: Reverted to Cemu 1.6.1 to see if it was related to the Optimized file operations + AES-NI support in version 1.6.2, but same error.
