MAMEWorld Forums - Hardware - Ground Up Emulation Setup Thoughts (CPU, Monitor, Cab)

Hi all,

Completely new to arcade emulation. I'm tinkering with a guy on met on the set of a shoot who is great at rebuilding custom cabinets but hasn't had experience with creating emulation setups. I'm currently plotting out the main guts for the job and wanted to get the experts thoughts
-Computer: Trying to get something that's cheap but will do the job up through GameCube system. I honestly don't think I'll dive into PS3 or WiiU for example. Here's one I found quickly on Best Buy: https://www.bestbuy.com/site/lenovo-...?skuId=6325578
-Monitor: I'm hoping to have a 32" screen mounted into the cab. I'm thinking it will auto adjust between 4:3 and 16:9 right? I don't care about black bars for 4:3. Not sure if a computer monitor vs. tv monitor monumentally changes things based on usage. Current target: https://www.bestbuy.com/site/tcl-32-...?skuId=6315439
-Cab: He has a centipede cabinet available that he can use as a base. We'll have to get into if the 32" screen size will work but what are your thoughts on the space for a 2 player setup with enough buttons to play the vast majority of games available for MAME and other systems?
-Misc: How do you do save states with arcade cabs? Do you have to go to the back end with a wireless keyboard or can you get dedicated buttons in the play area?

THANK YOU so much for the help!
