LIBRARY
- DMA
- added HALT_Z80_ON_DMA flag in config.h to enable Z80 halt on DMA (avoid corruptions or sound issues on Tectoy MD).
- deprecated 'vdp_dma' unit now forward calls to 'dma' unit.
- added wait DMA checking (DMA fill or DMA copy operation) before doing a DMA operation.
- SPRITE
- simplified sprite sorting (always enabled, just need to use SPR_setDepth(..) method if needed)
- fixed a regression which was causing 1 frame latency in sprite update.
SAMPLE
- minor change to sound sample
