If this was really to prevent spam, this really did more harm than good. This was really bad for us in the KOTOR community. Much of our guides are 5 times longer than the current limit on SRC. Before it was limitless iirc, but now it's 10k characters only. We had to migrate all of our guides to Github. Which is a big shame considering this site was so convenient to use for us. I'm currently in the process of moving KOTOR 2's guides over. Big disappointment. I really hope this is reverted.
Edit: to those wondering, yes, the guides are still up. But we can't edit them without deleting a bunch of text, which isn't possible considering how complex these games are. This might have been reported already, but the markdown is super broken. You can see the asterisk, '[b]', '[h]', etc etc, now all visible and doesn't do anything. I really hope the character limit and the markdown is fixed so we can migrate our guides back over.
Emulators are something we've never really discussed. We primarily run the game on console because it will always be faster than emulation. PSXFin will work with the game just fine, but I think other emulators like Bizhawk will also work as well. ePSXe is really glitchy and versions above 1.6 are usually banned because of its inaccuracies. I've never tried out Duckstation, but it might be worth a try as it's generally allowed in other speedrun communities I've seen.
If you're planning on running Any%, only few emulators will be compatible with kernel menu. I will not provide the ISOs for Xenogears nor the Chocobo Mystery Dungeon demo disc (if you plan on running JP).
