It let me open the swf file, but nothing loads on the screen, its just a blank google page. I really want the speedrun version.

How did you load swf for your current PB? You should be able to do it the same way with the speedrun version.

I used flashpoint, does flashpoint have the speedrun version?

Ah, I see. You will need to download Adobe Flash Projector to play the speedrun version. Check out http://twhg.info/getting-started

Thank you so much i finaly figured it out! But I must ask, why are there 8 versions of the speedrun version?

The original speedrun version is by Pzula released in 2018. Over time, more features have been added, so the current version is v8.
