Pokemon Mystery Dungeon Red - Lucario Rank Get

Note 1:
To break walls indefinitely, max out your Pokemon's IQ, and leave the 'Super Mobile IQ activated'.

Note 2:
To get a +X on your move, set it to your Set Move and drink a Ginseng.

Note 3:
Charizard learns Heat Wave at Lv1 from the Gulpin Link Shop.

FINALLY, after long gameplay hours, I managed to get the Lucario Rank, out of doing 7/8 of the S ranked missions in Silver Trench. Only selected floors are shown in the video.
