This is my attempt to do smooth scrolling for the Colecovision. I want to recreate Adventure of a Witch for the Colecovision. It's smooth but not perfect. It get a bit glitchy as the tree descend on the last third of the screen. Every 8 frames, put_frame update the new tree's position. Seems to run at 60 fps, but I slowed it down to capture this gif with the Gifcam. I still have Megaman 2 explosion in this. Even that made it hitched a little. If I update put_frame() every frame, then it'll have lag. One thing I learned from Making Adventure of a Witch is load handling. I update the random tiles every 8 frame on frame 3, then update the score every 8 frame at frame 5. The game needed the control and the tree update every frame. Without that, the game will lag and eventually give me an out of memory message. Although the trees are update like the original. I will add RND function to change the x and y tree's position once their y axis hits 28(to move it to 250).

In this version, I'll have the flying level be fixed. Add top down adventure mode.

There's so much game I want to produce.
