What frontend and MAME setup best supports 4-player arcade on LCD?

[John.S]

I've finally sourced all the parts to build a dedicated arcade cabinet, and now I'm diving into the software side with arcade emulation. I'm aiming for an authentic experience with a focus on classic fighting games and shoot 'em ups from the 90s. For those who have built similar setups, what's the most reliable frontend and emulator combination for MAME and other systems? I'm particularly confused about managing different ROM sets, configuring controls for four players with trackball and spinner support, and getting the video settings right for a modern LCD monitor to mimic a CRT feel without input lag. How do you organize your game library and handle BIOS files, and are there any specific settings or patches that are essential for games like Street Fighter III or Metal Slug to run correctly?
