I have been doing some research with mobile TAS tools, and have found a few things.
First is that BlueStacks has been looked over for tasing for a few reasons. I think most of those problems are now fixed, except that it will probably not ever have frame advance. This is due to the fact that BlueStacks tries to be as close as possible to a real android device.
Second is that pre determined input is near impossible with tools like GameGuardian. However, with BlueStacks, it is possible to make a “Script” to play predetermined inputs with a specific time between each input. This is extremely close to tools like FCEUX and allows for scripts to be shared very easily, by only needing to copy-paste the script.
Lastly, there is a large community wanting to TAS mobile games, and it has been brought up before (
here) This will allow people who maybe were intimidated to TAS the opportunity to see a new era to TASing.
I think this is the time to show that absolutely anything can be TASed, even multiplayer games, and show that it is easy and possible for anyone.
