Would probably still eat up a lot of DMA time, wouldn't it?

Well here's the thing.

Currently I have to do 3 blits for each background plane, their sizes are 19 words wide by up to 184 pixels in depth (3,496 words of data).

So each frame it does 3 blits of 3,496 (10,488) to render the entire background with the blitter.

[Incidentally if you look closely on round 5 of Rygar I just about have enough cycles at the start of the frame for it not to need a double buffer

But with the hardware sprite technique described I would need to copy in 5 words by 184 depth (3,680 words of data) for each sprite, multiply that by the 4 sprites and it's (14,720).

So the way I look at things... 10,488 words are processed with my current solution versus 14,720 with my proposed solution, however... and this is the kicker, if I double buffer the hardware sprites and run the parallax at 25 frames (which is pretty normal for a background layer) then I can half the words processed per frame cutting it down to 7,360.

So frame 1, update buffer 1 with sprites 0 and 1, frame 2 update buffer 2 with sprites 2 and 3...loop.

I have a hangover today, so all this might be just a load of shit that I'm thinking...but it feels do-able.

I saw the live yesterday and it seems Rygar has been updated again, it seems smoother, a bit slower.. very very close of the Arcade speed !!!
I see also, the stone from the end level entrance has been reworked...
Sincerely, yesterday, i when I arrived, I was pretty sure it was the Arcade version that was running ..., and the menu appeared, and it was the Amiga version

Thanks for watching and very appreciated.

Any one who was watching would have seen some odd bugs there which I am still trying to sort out. While they are not show stoppers, they are a little annoying.

I'll try and fix them before release... if not then I will fix them as patches.

The good news is that @jotd as built a WHDload version ready for release.

Good stuff.

Geezer

The boxed versions are for the developers and a few other people....

however if people want a floppy disk and a nice label then I can send them one for a small fee (i guess just PM me).

Just watched 1 hour 45 minutes of the stream. Good to see many known faces on there; even ross turned up

Real shame that I missed it live...
