Emulated Online. A few hours later after I submitted the run, I just noticed that I just failed to look at the rules for the run. and there is a better chance for this to get rejected. There goes my run...

Mod edit: I had a look at the online emulator used in this case. My findings: The page is extremely questionable, I do not recommend using it. Despite that it uses emulatorjs.com to emulate games, which uses the open source project EmulatorJS. The payloads to load EmulatorJS in this case requested the core "gb", which according to the documentation will use the Gambatte core. As Gambatte is an allowed emulator according to our rules I did look into if EmulatorJS runs it accuratly. It seems to be doing so (concluded by me after some simple verification steps I did with this video). So I will allow this run to be verified, but please in future runs use standalone versions of one of the allowed emulators, my personal recommendation is Gambatte Speedrun.

yeroc5311's note: Thank you for letting me through. I have redone this run on the gambatte emulator and a better timer on a Virtual Machine. (computer in a computer program)
