Supersonic Ball (by DJ, in Axe) is a better sonic clone than that, physics-wise. It just doesn't have much in the way of content.

actually Super Sonic Ball was kinda buggy in terms of physics too, since it was made before Axe added fixed points and stuff and it was one of my first true Axe game ever. I had to add a speed cap too, since otherwise you would end up going through wall corners. Notice for example how accelleration and gravity aren't increasing/decreasing smoothly. With my coding skills, I think Super Sonic Ball would be more suitable for the HP Prime.

Yeah I think the uploader added some other 8 bit rendition of Green Hill Zone over the game vid, it sounds like the Sega Master System version actually.

I'm sure you remember the Sonic project on UTI back in the day don't you James? I doubt the 84+ CSE would be able to keep up that well with a sonic game like you say. The older models wouldn't be that bad though.

I've long hoped for a really cool Sonic game on the 83/84(+) series. I wonder how feasible it might be on the 84+CSE? Horizontal (hardware)scrolling should be fine, but I don't think vertical would be an option (alas, that is why Alien Breed on the 84+CSE will probably never happen )

Actually I think vertical might be possible, but only at reduced frame rate. The max would be 8 frames per second at 160x240 resolution.

Also I can't wait to see your first 84+CSE game!

EDIT: That reminds me, since I am getting a CP400 soon, I might test how fast graphics are on it. If there isn't the 0.3 sec delay between every graphic object drawing like on the PRIZM, then maybe games could at least have rectangular stuff to draw walls.

I can't help but like the game. It looks pretty sweet. ^^

looking nice!
