I'm somewhat planning on speedrunning Poptropica at some point and was wondering some things.

• Can I use Flashpoint for speedrunning AS2 islands?
• Can I use an old version of Chrome to speedrun AS3 islands?
• Would I be allowed to switch between Flashpoint, Pop on old Chrome, and Pop on new Chrome in order to do runs with multiple islands?
• I'm kinda new to speedrunning, so how do I set up a timer in a recording/stream? Thanks
