Hardware wise, my PC is as follows:
Intel i7-4790k (Overclocked to 5GHz), AIO water cooled.
16GB DDR3L RAM
Radeon R9 280X Graphics card
Nvidia RTX 2060 Super Graphics card
1x 1Tb SATA SSD (Boot)
3x 16Tb SATA Hard Drives (Storage)
Currently no motherboard
Everything except the drives has been cast offs from the kids gaming PCs.
It’s kept in a Play Scene JAMMA cabinet, with the PC built using one of these:
There’s also a J-PAC adaptor to connect the front panel and CRT to the PC.
Software wise, I use windows 10 along with the AttractMode front end. The main emulators are GroovyMAME and RetroArch. AttractMode has been significantly customised to allow me to build nested menus. I’ve lost count of the number of batch files and scripts I’ve had to write to get it all working together.
I think if I ever get rid of the CRT monitor, I’d look into the shader and effects packs but until then there didn’t seem any point. I do have a Samsung (Non-widescreen) 21.3" LCD monitor that’s pretty much a direct size drop in for the 24" CRT but I’ve resisted the idea. I think once the CRT or Radeon dies I’ll think about it.
