; SL0P MENU - a top-level cheat menu opened with SELECT in the overworld
; (hooked in home/overworld.asm). Table-driven: each entry has a name in
; SlopMenuText and a handler in SlopMenuHandlers. A handler returns:
;     carry SET   -> a map warp was started; exit the menu and let it proceed
;     carry CLEAR -> return to the SL0P menu (redraw)
; Handlers may be submenus (WarpSubmenu, GiveItemSubmenu) or direct actions.
;
; To add an entry: add a "NAME" line to SlopMenuText, a `dw Handler` to
; SlopMenuHandlers, and bump SLOP_MENU_COUNT.
