>>11845783 (OP)>>is a shitty emulator made 25 years ago, played through a shitty 27 year old console the best way to play a PS1 gameThis. If you're going to emulate MGS, just use a modern damn emulator rather than a 30 year old one on a system that I assume you are still going to emulate itself. That's like emulating the Sonic collection on PS2 instead of just emulating the originals.
Either play it on an actual PS1, or use a modern emulator on your PC, don't bother with Bleemcast in 2025 on either real or emulated hardware.
