This was announced during state of play for PS+ Catalogue feature however, you can also fully own the game: PSN Store Page

From my initial testing, it runs much smoother than the PS2 without any major FPS drops, better loads, more responsive...etc. Although, it does not feature SP glitch which isn't really an issue compared to the overall performance.

The game comes with all available version:

• NTSC-U/C
• PAL
• NTSC-J

You cannot change the NTSC variant because that depends on the PS4/PS5 System Language setting. You will clearly notice that with the game cover art change for NTSC-J vs NTSC-U/C.

We have added PS4 and PS5 platforms, since you are now able to play the game with these. Keep in mind that additional tools that they came out with such as save states are not allowed in the runs.

If you have any other questions about this before attempting a run, do not be afraid to reach us in the dms or discord. Thank you and Happy Running.
