I think this was answered in the discord as well but ePSXe is good and the difference is mainly load times/cutscenes and the ability to menu hop easier on PSP.

Hello,

If you are interested in submitting a run, please note that run verifications will be locked until October 10th, 2022. This is to make sure we have the ability to properly verify runs as well as provide time for the community to enjoy the game on a casual level. You may still submit your runs but they will not be validated until October 10th. If you have any questions, please leave a comment here or DM me on Discord @ Psyonic Panda#8355

Hi, it's been 9 months but figured I would update my reply. If you want to do a run on an emulator, I will accept it. I might take more time to review it to check but I imagine the differences shouldn't be too large. Getting more runners in might be a good thing. If this game ever takes off, I might put emulator in it's own category but I don't think it will be an issue at all.

This game has a lot of loading times. I would say having much faster loading could save minutes. On top of that, it is hard to verify. Modifying game speed and other things make it more complicated. I think I am the only active mod at the moment, so making it as simple as possible would be nice.

Currently there are no runs that use it. I practice on emulator and submit on official hardware.

Edit: Emulators are allowed. Please check the post below!
