OCS sprites outside of bitplane area is possible (officially supported on/off bit only in AGA): write to BPL1DAT once somewhere in the beginning of scanline and sprites appear normally until end of scanline. (I don't remember if BPLCON0 needs at least one enabled bitplane but at least this works outside of DDFSTRT-DDFSTOP range)
Can be combined with normal bitplanes (and can cause some display "alignment" issues) Useful if you want to save DMA cycles but for example still want to have something visible in left or right border.
