No sprite flicker rom and 15 sprite per scanline rom for AVS

13 posts in this topic

These are only meant to be used in hardware or emulators that can take advantage of the no sprite flickering.

 

 

This rom completely removes sprite flickering with the following patch

 

SET(0x2d04C, 0xA901209ACC4C3C90)

TSB_no_sprite_flicker.nes 

 

You would need to use this in nestopia with the Machine->Options No Sprite Limit checked

 

 

This next file would take advantage of the upcoming AVS's 15 sprites per scanline feature

 

This patch changes the check from 8 sprites per scanline to 15. You could also use this in nestopia as with the above using the no sprite limit option to see how much of an improvement it makes (A LOT).

There are no other hacks on this rom? I love it. I'll send this to my contact and see if he can post another video to compare it

Mog had loaded these on to a power Pak and said the results were very interesting. He should have a video available soon

Hello, I am the one who is posting the AVS recordings on youtube.

 

Here is a video showing both of those ROMs with 'extra sprites' off and on. The 'sprite limit 15' ROM looks pretty awesome. Nice job!

Thanks for the demo! Can you hook me up with a free AVS? Just kidding. 

 

That looks about like what I expected. Only the 15 sprite limit rom is OK to use in the AVS even with the extra sprite setting turned on.  

 

I checked the sprite counters in FCEUX and you still get more than 15 sprites per scanline in certain situations like kickoffs, punt returns and tackles where there are a bunch of players all on/near one horizontal line.You'd need something like 22 or so sprites per scanline to be safe

 

The 15 sprite limit on the AVS improves the flickering by a lot.

1. Does this overwrite any other known hacks or is this a fairly isolated location?

2. Did you test this out in Nestopia without the No Sprite Limit checked? Are there any adverse effects?

1.It is isolated.

 

2. Yes. It worked great from the little bit of testing I did. If anything there might be a tiny bit less chance of slowdown since it cuts out cycling the sprites and some logic checking.

WOW! Awesome hack! I tested it with VirtuaNes, no problems either. Really retarded question. If this hack were applied to a rom that got burnt to chip, what would happen to the game when someone plays it on native (NES) hardware? Would it bomb, or just not have an effect?

The players would dissapear completely if there were more than 8 sprites on a line so you wouldn't want to use  this on an old cart + nes
