Wow! This looks quite nice. I may steal the 5-mode concept from you, it seems like it's working great and would lead to a robust engine.

Wow that is too great! I am amazed at how you managed to get the physics so close (well... faster but still...). On top of that, it was at 6 MHz! I tried it at 15 and it was ultra-fast.

Do you think with smooth scrolling it could be fast enough?

Its not my concept so go ahead :)

And shmibs that sounds like what i have done, we will have to compare engines :)

And thanks DJ :) I hope smoothscolling can work, as that is kind of what i am aiming with this whole tech demo.  I just need a fast enough engine and it should be good.  It is surprising how little power it takes to run this physics engine.  Even in Full i didn't get the speed increase i expected because the framerate was getting to the max the calc could handle O.O and i haven't even optimized it!  I guess the guys as Sega knew what they were doing :)

Well not every technology company is like TI ;)

Well, they did. At least for the classic Sonic games. The new ones are really not that good, unfortunately.

Spoiler For Projects:

My projects haven't been worked on in a while, so they're all on hiatus for the time being. I do hope to eventually return to them in some form or another...

Spoiler For Pokemon TI:
Axe port of Pokemon Red/Blue to the 83+/84+ family. On hold.

Spoiler For Nostalgia:
My big personal project, an original RPG about dimensional travel and a few heroes tasked with saving the world.
Coding-wise, on hold, but I am re-working the story.

Spoiler For Finale's Super Insane Tunnel Pack of Doom:
I will be combining Blur and Collision Course into a single gamepack. On hold.

Spoiler For Nostalgia Origins: Sky's Story:
Prequel to Nostalgia. On hold, especially while the story is re-worked.

Well i was talking more on the code efficiency part, they came up with a method that is super duper fast ^^

True, especially remakes of the old ones as well as ports. The worst is Sonic The Hedgehog Genesis for the GBA. It's filled with physic glitches.

Yuk, although the site i linked to does mention a glitch in the original sonic where if you fall from too high you can pass through objects D:

heh yeah they fixed it in all the later versions i believe, there might not have been even that many places in the original sonic where you could even build up enough velocity o.O

Haha I think that happened in Supersonic Ball before I slowed down falling XD. When moving down at a 4 pixel interval in a direction AND vertically, then landed in the very corner of two tiles, you went through it.

Reminds me of a flash game I played called Flipside, where you can drive up walls in your car, if you have enough speed. A calc version of flipside could be done with physics like this, too.

Wow, that flash game takes A LOOOOOOOONG while to load O.O. It reminded me when we had dial-up at school, shared between 64 computers O.O
