Rotating BIG sprites

[Sumez]

I can barely see the tearing on my PAL SNES+CRT TV.

"It looks a lot better after it's been blurred out."

Three words: R, G and B.

RGB from SNES is kinda blurry, due to what seems like the DACs only being able to source current (transitions toward 5V are straight lines but towards GND they're gradual). 1chips apparently fix that. Still way less blurry than composhit, and no dot crawl artifacts lol

Today I wasted time trying to make a double buffering system that start the next rotation frame directly after it gets done with the previous frame if it takes more than a frame to draw.

My big mistake was using a double buffer instead of a triple buffer.

Now that I got it running at practically 60 fps, I think I'll add scaling into the mix, but I have to rearrange the format again just to apply it.

Do you have a ROM demo of this ?

[psycopathicteen]

Yeah

[Stef]

Thanks, just tested Definitely impressive, i wonder if you will be able to get a full game from it at some point

Looks great on bsnes, but black screen on hardware (3 attempts) and ZSNES.

impressive, i think there is some hardware init problems, it works fine on snes9x, but the music works only after a reset .
If you let some foes coming to the most left side and kill them, there is no slow down even with sprite rotation.

@psycopathicteen: Do you rotate the entire sprite or only the alf and use mirroring for the other half ??

[psycopathicteen]

I rotate the entire sprite.

I do notice some framerate drop with the rotating sprite when I let enemies follow me back.
