Hi all first time post, started using Launch box for my build and all was going ok. I then started using Retroarch and it all started to confuse me. When i first added an emulator through Retroarch i picked it in the first drop down menu and then on the second drop down menu i clicked on the destination path of the Retroarch exe file. All seemed to be ok and started on the next one, on the first drop down menu it says Retroarch has already been used ? . So i used the name of the core for the emulator i was using and picked the exe for Retroarch again but it wouldn't work ???. Going through this process i accidentally deleted a working emulator and i cant seem to work out how to add an emulator for all of the roms eg Sega Genesis, i have 30 roms and can work out how to put the emulator on singular roms but not as a batch lot.
My 3rd question (if you understand my last 2) is how hard is mame to get working, I obtained some roms and nothing they dont work with any of the emulators. I even tried getting a 164 rom and loading 164 mame but still nothing.
thanks for listening i thought that the woodwork wood be the hardest part of the build, it is proving otherwise at this point lol
