I'm currently working on a Midnight club LA remix tas. Its not gonna be perfect, as these types of games are very hard to truly optimize. The RTA record is 7h17m and is a complete mess. Theres even several races where he doesn't get 1st place. Which to be fair, I couldn't do it any better in 1 sitting.
Optimizations include: not banging into walls on turns, maintaining a high speed, using slow mo ability when necessary, not crashing into any cars, heavy use of slipstream turbo(pretty much required to win).
My only fear is encoding is gonna take forever. On my machine, I'm using intel n150 with 16 gb of ram. Running linux mint zara. The linux build of ppsspp currently doesn't recognize input. I'm sure if the linux build was fixed, it would be boost performance. But for now I have to use wine..
If the linux build is fixed, I may restart the run. There is some routing errors in my current WIP.
