I’m looking into building a racing MAME for my grandpa because he and I used to love competing against one another when I was a child. He can’t really get out that much and recently mentioned that he loved doing that with me. I wanna surprise him with a game we can play together and want to know how I should get started with the software. I have Launchbox because I build and sell custom arcades so I’m pretty familiar with that already. Any tips or recommendations would be greatly appreciated! thanks!
