Enum JyBoard 

pub enum JyBoard {
    M90,
    M209,
    M211,
    M35,
}

Which iNES mapper number wired the ASIC. Selects the ROM-nametable / extended-mirroring policy and the mapper 209 MMC4 auto-latch behaviour.

Variants

M90

iNES mapper 90: ROM nametables / extended mirroring jumper-inhibited.

M209

iNES mapper 209: standard implementation (feature register-enabled).

M211

iNES mapper 211: feature always enabled (a 209 duplicate).

M35

iNES mapper 35: the J.Y. Company single-game “extended” board (YY840820C / J.Y.061). Same silicon as 209 — the ROM-nametable / extended-mirroring feature is register-enabled — so it shares the 209 policy (incl. the MMC4-like CHR auto-latch). (v1.6.0 Workstream E.)
