I was doing so a while back, when I had more time and Balatro single-deck runs were my main way to chill out between classes. School ramped up though and eventually other games replaced that though.
For those who care & know enough to want to volunteer, mod apps are currently open on the Discord server:
Dunno if anyone really cares, but the Discord invite attached to this leaderboard doesn't work anymore. Just felt like dropping an FYI in case someone would want to replace it.
While true,
(1) We time by IGT, and I can't imagine there's a big difference there between the two.
(2) To my understanding, PS2 is just really good, 99.9%-compatible PS1 emulation, with some small perks according to Google. The main benefit you might get is a slightly faster time RTA, especially with the fast disc speed option, but apparently that can cause crashes.
Pretty sure there are some nuances between PS1 and PS2 that the better runners are more familiar with. Though most activity right now seems to be more or less split between PS1 hardware and PS1 emulator AFAIK.
