#REDIRECT [[J.Y. Company ASIC]]
FCEUX's source says [[iNES Mapper 035]] represents [[wikia:c:bootleggames:Wario Land 2 (Famicom)|a pirate ROM hack]] of Kirby's Adventure.
{{DEFAULTSORT:035}}[[Category:INES Mappers]][[Category:Mappers with ROM nametables]][[Category:Mappers with scanline IRQs]][[Category:Mappers with cycle IRQs]][[Category:Mappers using J.Y. Company ASIC]]
That implementation looks a subset of [[JY Company]]'s mappers, supporting/using only the registers at $8000-$8002, $9000-$9007, $C002, $C003, $C005, and $D001.
 
$6000-$7FFF: PRG RAM bank
$8000-$8002: PRG regs
$9000-$9007: CHR regs
$C002:  Any write here will acknowledge and disable IRQs
$C003:  Any write here will enable IRQs
$C005:  IRQ Counter
$D001: Mirroring reg
    Mapper 35  JY Company
  ------------------------
  %00 = Vert  %00 = Vert
  %01 = Horz  %01 = Horz
  %10 = 1ScB  %10 = 1ScA
  %11 = 1ScA  %11 = 1ScB
 
This is probably either a duplicate of one of mapper 90's variants, or yet another variant.
