A naive check using https://psxdatacenter.com where I assume that no english = not available. If there are instances where there is a NTSC game that has a PAL release in a non-english language let me know. Also let me know If I've been fooled by alternate names

I'm a bit worried deleting stuff is double deleting so let me know If I'm missing anything
