Hi, so I am new to building an arcade machine, I just bought a Rec Room Masters cabinet and a GMKtec NucBox M7 Pro Mini PC AMD Ryzen™ 9 PRO 6950H to run in it with 32GB ram and a 4 TB SSD. Looking at some of the TONS of you tube video's out there I THINK....big emphasis on THINK.....I may have a plan for populating my arcade. I guess I should note that I am really just wanting to play classic arcade type games (including some laser disc games like Dragons Lair) and maybe some vintage console games from Sega Genesis and Gamecube... So, my plan is to get Lauchbox/Big Box (paid version), and import MAME. I am looking at Myrient to download the MAME ROM Sets (before March 31), and I was looking at just downloading all the non merged ROM's in the MAME folder, as from what I have gathered that is easiest and would be all I needed to get started? But....Looking though at Dragons Lair specifically I have read you have to have the CHD files for that, but they are only in the "Merged" folder in Myrient....so if I go "merged" I would then need the Merged ROMs, the BIOS-devices files and the CHD files? Then organize it and let Big Box sort it out? Thanks in advance...
