Zach found some time to keep on working on his Tetr*s game called Chetiry.

Author notes:

Just wanted to let you know that I haven’t given up. I’ve had more time for programming this summer and got a lot done this weekend. Mainly I’ve been busy adapting the game to standard memory, rather than the RAM+ bankswitching.

With the latest demo you can move pieces and rotate them, but rows don’t dissappear yet when they are full. Note that the score and next-piece icon are not active yet. Also, I took care of the wrapping problem when moving to the left or the right, but you can still wrap while rotating.
