Problems with Sprites wider than 16 pixels when the Blitter is ON #8

Hi Mr. Pink;

Congrats for this amazing Lib. I find it very useful :)

I guess there is a little bug in Blitter.C because when the sprites are bigger than 16 pixels and Blitter is ON there are a lot of flicker and sometimes the sprite is not printed in its totality. When the Blitter is OFF all is ok when the sprites are bigger than 16 pixels.

Thanks in Advance, José Mário aka MadAxe

I'm glad you are using and enjoying the library!

I have a few questions about this issue:

Are you noticed this problem on real hardware or on an emulator?
If emulator, which emulator are you using?
Do you have a small code sample that reproduces the problem?

Hello!

I'm using an emulator. I tested on both Steem and Hatari and I get the same result.

Well, I'm coding a little shooter but you can see this happens in your sample BLITTER1.C after raise the sprite and mask width from 16 to 32 for instance.

Hi!

Did you find anything wrong in GodLib or that's me who is doing something wrong in my code?

Cheers, Mad.
