# Note that I have changed the default for IOP reset, as this has been
# long-term tested now, and proven superior to starting without it.
# I have also changed the default for CDVD checking, as the old default
# could cause lockup on some PS2 models if started with empty tray.
# ----------------------------------------------------------------------
Init_CDVD_Check = 0
Screen_Interlace = 1
Init_Reset_IOP = 1
Menu_Pages = 1
