I need some help.
What is the best way to mirror the byte?
(for ex. 10010011 -> 11001001)
I mean, if there is a simple way to do it (may be with OR, AND, XOR and so on), I'll be able not to store a mirrored copys of sprite in memory..

Hi everyone
If i select the Image Editor on YSM Sprite Designer and try to use any option (S for colours, C to clear grid etc.), nothing happens. It doesn't work.
Why?
I'm running it on FUSE 48k

Thanks
