"SEE Through Walls" Game Genie Codes!?!?

[OldSchoolGamer]

We all heard of "Walk Through Walls" game genie codes. But what about "See Through Walls" game genie codes? Would that even be possible? Has it ever been done before? How cool would it be if you were able to see what was in the next room before entering it by "seeing through walls" while playing (NES) Zelda or (SNES) Legend of Zelda: A Link to the Past.

Also could somebody please make a "X-Ray Vision" Game Genie code for the treasure chests in (SNES) Legend of Zelda: A Link to the Past.

I also posted this request in the thread: http://gshi.org/vb/threads/5327-GG-C...ast-SNES/page2

(My bad on the double posting of the "X-Ray Vision" Game Genie code request)

I'm so new to hacking, I wouldn't know where to begin In the case of Zelda, a joker might be used to scroll the screen into the next area without placing your character there, but it's just a guess. It would take a ton of codes if successful, and would be best used as a patch.

An x-ray cheat might be possible for Super Metroid, where you could view hidden passageways and the like. It would use the x-ray item, though as a consequence the gameplay might become terribly slow. The shape of the x-ray beam would need to be modified (to a circle or something), or maybe the real layer could be exposed all the time.

One easy way to get x-ray effects is to toggle certain foreground layers in your emulator, but I'm sure you're looking for something more interesting....

The super Metroid Thing might be possible, might try it but the zelda code would require alot of work to do. You would likely have to find the routine to scroll the screen and make it jump to that routine but then it would have to jump back to the original location , and it might also cause the game to think you are in that location and when it snaps back to where you where the character coordinates might be off. Of course this is speculation from experience hacking zelda and similar games.

Isn't there a "X-Ray Vision" cheat code for one of the SMB games in which it shows you what powerup is in the brick/block? Or am I mistaken?

Oh yeah, it might get ugly... You could have a routine that reads the next area and traces out its tiles. You wouldn't have to worry about scrolling if you just have a simple 2D loop... not sure how to go about reading level data though.

Such knowledge would have helped me today, as I needed to read a single tile and feed it back into another set of codes. The cheats I made are worthless without the ability to sample level data

In a more modern system like say the NDS with a heap of code types and very powerful ones and also a large area of ram to store custom routines its very possible but with whats available in the retro systems we are limited.
