Nintendo Entertainment System (NES), Famicom klonas.
UMC UA6527P – Hybrid (“Dendy”) CPU made by “UMC”. I know it has better DPCM, timbre and overall sound quality than TA-03NP1, but has 25%<->50% duty cycles swapped (6502 core)
UMC UA6538 – Hybrid (“Dendy”) PPU made by “UMC”. I’ve confirmed red/green emphasis swap on it. It has more saturated palette than TA02-NP-6538 and RP2C07-0.
