As of 2023 May, both are extremely inaccurate in problematic ways. * MAME * ePV-1000 (Part of Common Source Code emulator system by TAKEDA Toshiya ) [http://takeda-toshiya.my.coocan.jp/pv1000/] Both are problematically inaccurate. Here's a list of what they do wrong: * regF8, F9, FA: square wave channels should be different volumes (fixed in MAME release 254) * regFB: missing mute and ring/XOR modulation support..."

During each of the 192 active scanlines, if enabled in the configuration register, the ASIC does the following: BUSREQ is asserted from pixels 20 through 267; the other 40 pixels it's deasserted. The first two pixels are during hsync. While the Z80 asserts BUSACK # the ASIC continuously asserts /MREQ # the ASIC runs the same 8 pixel 4 fetch pattern: TilemapEntry Bitplane Bitpl..."
