TASvideos.org user Zupapa discovered the MSX to make TASes on, and he just submitted his 3rd MSX TAS to the site.
Here's an oversight of what he did so far:
Nuts & Milk in 05:09
Kiki KaiKai in 05:48
Skooter in 05:41
He said he's inspired by the List of Ideas, which you can check it out in the MSX tab here.
Do you have additional suggestions on MSX games to TAS?
