probably not, but theres nothing stopping u from running it normally and just submitting it to the normal boards
chances are this wouldnt get accepted considering it's just IM% with a vid comic attached to the end of it
loads aren't a big enough difference for the community to want to split, and the pda time loss comes from loads. this discussion has been had many times in the community and it's always resulted in no one caring enough to split the boards. also the ps4 game is a completely different game
ps2 and ps3 won't be split, the differences aren't big enough, feel free to look at the differences in this pastebin: https://pastebin.com/dAskhTm7
Judging from the loads in your run, I don't think SSD saves a bunch of time over HDD, but from what I remember others in the community say it reduces some of the menu lag the game has. I'd also recommend you join the speedrunning discord (https://discord.gg/pnCtS73) for other questions you have. We'd be more then willing to help you with anything you're having trouble with.
This is incorrect, the load times differ from pc to pc.
Any% Episode Shadow sounds fun
I feel like timing starting on first frame you can move is a good idea, kinda like Ratchet & Clank 1 does it
