V ROM

8 bit ROMs containing PCM audio samples in cartridges.

In early cartridges, the ADPCM-A and ADPCM-B samples were in two separate V ROMs. The PCM chip was later used to merge both types in the same ROM(s).

V A ROMs minimum speed: any will do (>2µs).

V B ROMs minimum speed: 350ns (see YM2610 bus timing).
