By default, the inp file we downloaded should be placed in 'inp' directory which is at the same level with mame.exe.

I found this sophisticated reason by recording a inp file that shows me the sub-directory created.

We can indicate our inp directory by '-input_directory' argument.

Here is my handy bash,

MAME_DIR=/e/game/ex/mame
MAME_BIN="${MAME_DIR}/MAMEv0.248/mame.exe"
MAMEP_BIN="${MAME_DIR}/mameplus_bin_x86-0.168/mamep.exe"
MAME_0229="${MAME_DIR}/wolfmame-0229/mame.exe"
MAME_0140="${MAME_DIR}/wolfmame-0140/mame.exe"
MAME_0105="${MAME_DIR}/wolfmameplus-0105/mamep105-vc.exe"
MAME_0101="${MAME_DIR}/wolfmameplus-0101/mameip101.exe"

MAME_ROMS_DIR=${MAME_DIR}/database/roms
MAME_INP_DIR=${MAME_DIR}/database/inp

MAME_ARG="-window -skip_gameinfo -rompath ${MAME_DIR}/database/roms -snapshot_directory ${MAME_DIR}/database/snap -input_directory ${MAME_INP_DIR}"
MAMEP_ARG2="-scale_effect hq3x"
MAME_ARG2="-nofilter"

{
        local win_path="$1"
        win_path="${win_path#/}"
        win_path="${win_path//\//\\}"
        win_path="${win_path/\\/\:\\}"
        echo $win_path
}

	(

	)
	
	rm -Rf ${MAME_DIR}/database/cfg

		rm ${MAME_ROMS_DIR}/${GAME}.zip
	fi
	rm ${MAME_INP_DIR}/${INP_FILE}
}

alias mame="${MAME_BIN} ${MAME_ARG}"
alias mamep="${MAMEP_BIN} ${MAME_ARG}"

How to use, e.g.

mame_inp mystston new 2
