NES 'Game Code Modifications' :p

[Saturn]

Don't recall ever playing this one before but it has to be great, considering the name. Since I'm on a roll here and coming off that masterpiece of a game in the last post on the previous page, why not continue the series?
I've linked to a video I made of my first time through. I died a few times during the earthquake portion of Stage 3 and apparently Invincibility doesn't protect against the final boss rising up from the floor if you're standing directly on top of him lol.
Another great game imho. Wish I would have owned this in my youth. Looked like it would have been a challenge on real hardware

Edit: Removed this from the main set as it crashes when trying to retrieve items in dungeons, like the bow in the first level, causing Link to get stuck in the dungeon where he would normally appear after reemerging from the stairs. (He can walk/run in place & turn but can't move forward)

Just played through this from start to finish. A one-shot deal. Never played it before that I can remember and that's probably a good thing
Attached is a FCEUX state save at the final boss. If you have the hacks below in the rom, basically just follow him around and punch until he's dead. What an ending! (Not)

I still have this cart in the collection. Remember playing it endlessly trying to master each level and that landing sequence. Also, the refueling connection in mid air to the fuel plane. What a pain! Didn't even see the fuel plane in this hacked version as the infinite fuel completely removes the sequence. Epic
