NES Sonic

...I feel as though I should be worshipping you.

Any particular animal you prefer in your sacrifices, or can I just go with chickens?

[Joe Redifer]

Sacrifice a hedgehog.

[evildragon]

i already sacrificed a two-tailed fox

[Vyse of Arcadia]

Buh-da-bum tish!

So how far along is this project? Can you give us a rough estimate, percentage-wise?

[evildragon]

it's been started since atleast a month ago.. percentage wise, it's about 30% complete..

it won't, and "can't" be published to the public, as it's designed for my NES DVD-ROM drive, and it uses special API's..

I can "try" and do this on a normal cartridge, but it is using some of the drives RAM as extra memory..

Put up a short Youtube video of it, I'd love to see it running, even if only for a few seconds and even if it has glitches.

[evildragon]

i don't use youtube, but i'd be glad to compress it in H.264 and put it on my webserver and link it here..

it won't have sound though, as i haven't finished coding the audio engine yet..

i am almost finished with the gameplay engine, so it should be soon..

[evildragon]

UPDATE: I added the physics engine on the NES port, and the framrate was totally raped.. The average frame rate with propper physics is 15fps (I think)...

I also changed the color palette.. I will have a video soon... I found my composite cables, so i'll be able to record via composite...

EDIT: Oh yea, the new engine also includes Tails to follow Sonic.. Come to think of it, THIS may be the frame rate penalty..

[Joe Redifer]

Awesome. Looking forward to the video.

[evildragon]

here's the NES.. i can't find out why capture cards hate 240p, but luckily i was able to capture at 240p, minus the artifacts... the color really does look this crappy on the NES.. the pallette is small..

Great, but where do I find the codec I need?

[evildragon]

QuickTime...

(I think VLC has it too. I chose H.264 to use less web server space, and smaller bandwidth)

[108 Stars]

Great work, evildragon!
Now if you could somehow manage to get a better framerate it´ll be awesome!
I would never think this is a NES game!

[evildragon]

I'm trying to figure out what is causing the slow down... possible causes include:

Diagonal Scrolling Driver (as NES can't diagonal scroll without software support)
Tails/Miles
Remnants of 68K (or even Z80) coding.. (as this is a direct code-port of the Genesis version)
Physics Engine

Somethings causing it, and it seems the NES gets stuck in a loop trying to complete a code it either doesn't know, or can't execute fast enough..

[Joe Redifer]

That's cool. It's running at 10 fps in the video. I'm amazed that it can have so many sprites on a horizontal line.
