On top of this, is the new L2 pixel priority engine and lighten/darken L2+ULA modes which you can get by setting the SLU order to %110 and %111 respectively.

- Added Next OS streaming API ( see readme )
- Added DMA reverse mode (R0 BASE, bit 2)
- Added BSLA DE,B (ED 28) shift DE left by B places - uses bits 4..0 of B only
- Added BSRA DE,B (ED 28) arithmetic shift right DE by B places - uses bits 4..0 of B only - bit 15 is replicated to keep sign
- Added BSRL DE,B (ED 2A) logical shift right DE by B places - uses bits 4..0 of B only
- Added BSRF DE,B (ED 2B) shift right DE by B places, filling from left with 1s - uses bits 4..0 of B only
- Added BRLC DE,B (ED 2C) rotate DE left by B places - uses bits 3..0 of B only (to rotate right, use B=16-places)
- Added JP (C) (ED 98) JP ( IN(C)*64 + PC&$c000 )
- Added new sprite control byte
- Added sprite expand on X (16,32,64 or 128)
- Added sprite expand on Y (16,32,64 or 128)

- Removed 12 sprite limit, limitations still apply when expanding on X (100 16x16s per line ma
- Sprite pixel wrapping on X and Y (out one side, back in the other)
- Added "lighten" mode. L2+ULA colours clamped. (selected using SLU layer order of 110)
- Added "darken" mode. L2+ULA-555 colours clamped. (selected using SLU layer order of 111)
