Is this possible? I know that the eboot from PS1 exists and it's stable, but I don't know is it allowed for speedrun

I haven’t played the PSP version of this game in like 6 years, but i can’t see anything being wrong with it. I forgot you could play it on that - I’ll add the platform so you can submit a run. Although I anticipate the boss fight and prison ship to be quite difficult without R2 and L2
