Overflow Chip Mux

overflow-chip-mux

The list/tag overflow indicator, replaced with real NES PPU sprite multiplexing: instead of collapsing extra items into a static "+N" pill, only 8 chip slots (the hardware's real 8-sprites-per-scanline limit) are ever visible at once, round-robining which contending item occupies each slot on a throttled cadence, exactly how 8-bit console flicker actually worked.
