However, being a long RPG, especially one that nobody outside of Japan would have played without the translation, a Japanese TAS of Mother 3 would be completely boring. I watched the Star Ocean TAS (which was the non translated, Japanese version) and I was bored out of my mind, especially since I never played that game before.
When I played Mother 3 English, I did notice that there was a lot of visibly noticeable lag sometimes with VBA (which might have been improved in VBA-M, but I dunno). I wonder if this lag exists in the Japanese version... Even if that lag did not exist in the Japanese version, the English version would probably be better for entertainment anyway.
Oh, and Mato posted that there may be news about an English v1.1 patch coming out soon in a recent update at
Earthbound Central. By the hints, it looks like it's just fixing spelling errors, though.
