How did they make Sonic?

[eatcomics]

They made Sonic with a computer.

Yes, but "How" is the question, not "With what".

I'm telling you guys the programmers of old were wizards.... I mean you should see some of the crazy shit they pulled off and the techniques they used...

z80 ummm
m68k asm since the genesis/md was a m6800 processor
(same as amiga/st as it goes), assembler none the less

hope its ok to poke this one, i see its old but im new...

firstly yeh the 80/90 coders mainstream and hackers was well outof this world
fitting whole games in to same size we email a low res pic...
and pushing the limits ... its a bit of a lost art now SHAME

what interests me most here is the tilemap/map engine
having phannied around with these myself over the years
and i thought i got stuck in rewriting engine & tile tools after couple month chucked it all in the bin
seeing ES still pushing there engine & toolkit kinda shows me i was rather short sighted and rushed

sonic and several amiga titles have really puzzled me
(al la the loops / wall runs mentioned earlier)

when i have experimented with this, due to my lack of knowledge & ability to hit right tuts
slopes/hills have always been bit of a msytey ( and i dont class tiles with just diaganal from tl/br to be slope)
so "how did they make sonics tile/map engine"
and again i dont need to know basics square slopesor tile based jump slopes (like mario bros)

anyone care to elaborate / or point me somewhere

having stumbled on on ES & Gyros vids YT vuds (FTW GUYS BTW!) has really made me wanna revist this kinda stuff
AND BOTTOM IT ONCE AND FOR ALL lol

the way things work in that game are so interesting haha ..it's what I've been most boggled by since i've noticed it in Sonic 2 for the Genesis. like sonic can go up ramps, like a skateboarder would go up one, and like in the collision of sonic and the side of a ramp, he would launch off the ramp like a real object would. thats just awesome haha. I guess that sonic's character and the ramp objects use a kind of pixel perfect collision to get it so accurate? everything in that game is interesting from a "how does that work" perspective haha.
