`TUBO` on page 1 is also one of those bistable/latch type cells. I'm not sure what function it provides there. I find this whole circuit around that cell very confusing....
Also there are `CYTO`, `FEMU`, `FYFO`, `GEXU` and `KEZU` on page 13, `BUTA`, `DALA`, `DANE` and `JEME` on page 15, `GOFY` and `GUGU` on page 16, `FOZU` on page 18,...
Just found `ASOL` on page 1 and `LYXE` on page 4.
I found out how to distinguish between those two latch types without looking at the supply rails: 
Same goes for the volume envelope of CH4. It needs AO_MUX_2 cells instead of AOI_MUX_2 for `FOLE`...`ELAF`. The two AOI_MUX_4 cells on the same page (page 20) also need to...
Also on page 20, the AOI_MUX_2 `KAVU` gives a different sound when changed to AO without I. I tested it with FF22 = 0x83. When `KAVU` is an AO it...
> Also is it correct that OAM_A_D7-0 is XOR'ed with inverted H7-0? How does that work? This works because OAM_A_D[7:0] and OAM_B_D[7:0] are also inverted. See #57. All data inside...
Yes, exactly
Just wanted to throw this out there, because I think it is interesting: After eliminating ``VAVE`` in #22 and "re-connecting" ``VYPO`` in #20, the net labelled ``P10_B`` is the only...
@rgalland thank you very much, that's great to know. I haven't simulated the PPU yet, so I wasn't sure about this ground connection, until now. ^^
