Interesting, I am goign to give it a try. Was the GUI inspired by the one from Crystal Soft's PC-98/FM Towns/X68000 'Virgin Angel'VN released in 1995?
Yep, that's the one! We're going to have a motherboard then throw a bunch of bullets on the table XD
The middle part is 4:3 and when put in the middle of a 1080p game, it creates enough space for those iconic thick borders.
