  • Opcode: 0xE3
  • Short name: BGROL2
  • Long name: Background Roll (Reverse)

Memory layout

0xE3 B A

Arguments

  • const UByte B: Bank to retrieve A, or zero if A is specified as a literal.
  • const UByte A: The ID of the background area to roll, as specified in the background's sprite.

Description

Similar to BGROL, except the roll runs backwards through layers, rather than forwards. Rolling backwards past layer 0 for the area specified results in no background being shown.
