; 2. does not have the player start in floor two of the player's house (instead sending them to [wLastMap])
; 3. allows wild battles to be avoided by holding down B
; furthermore, in the debug build:
; 4. allows trainers to be avoided by holding down B
; 5. skips Safari Zone step counter by holding down B
; 6. skips the NPC who blocks Route 3 before beating Brock by holding down B
; 7. skips Cerulean City rival battle by holding down B

; bit 2: the target warp is a fly warp (bit 3 set or blacked out) or a dungeon warp (bit 4 set)
; bit 3: used warp pad, escape rope, dig, teleport, or fly, so the target warp is a "fly warp"
