Good luck with any game systems handheld or otherwise getting TPT on it anytime soon. If you really want to put TPT on a game system, then code TPT in C# or get a dev kit to make it compatible for a game system. They are very expensive. Then, you would have to recode pretty much all of TPT to where it would work right in another language. Then you would have to keep it up and go through peer reviews and get licenses for every game system you want to put it on. It is a hassle, costs a lot of money, and isn't worth doing.
