My version on how-to add PS3 games running on RPCS3 to Launchbox.
8.
I created a batch file to start each game individually, by doing it this way - I have more control over how each game should be run and configured.
Oh yes, each and every game I intend on running within Launchbox is encapsulated in its own folders with the RCPCS3 emulator (striped down of course.)
Creating a batch file example -
//
@ech off
color 0b
echo .
echo . Sonic & All-Stars Racing Transformed (USA)
echo .
echo . To exit Game - ALT 4
echo .
echo . Launcher created by your's truly
echo .
rpcs3.exe --no-gui ".\dev_hdd0\game\NPUB31090\USRDIR\EBOOT.BIN"
exit
//
You'll have to adjust the additional option in the emulator's GUI like Fullscreen, video type (Vulcan/Directx, sound, etc...
No doubt, It is repetitive and time-consuming when building it this way but I don't care about the disk spaces, and besides - 'IT's YOUR SYSTEM' YOU Make the rules!. This won't be an issue too much if you only play with 2-5 games - haha. ;)
Another good side effect of this method is that each game is 100% portable. This means you can copy it to other media (HDD, SDD, flash drive, fill in the blank...) and just play it without the hassle of reconfiguring it.
To Update the games, you can make a batch file to copy 1 RPCS3 that you updated to all the folders (but that's a how-to for another time ;)
