Hi, long time no see. I've been away from the "scene" of retro hacking cause reasons (mostly work and vacations from time to time).

basically the same codes as above (please include them in the Aladdin III entry) but THESE CHANGE

This isn't registered anywhere in the NES game section of codes

Also I had a hard time looking for codes for Super Mario World (NES) (Unlicensed) because it isnt' anywhere in the NES game section, nor in the Famicom section. I don't know if the Magic Carpet 1001 code is hidden somewhere. You can access if you know the game id (in Super Mario World is:
GameHacking.org | Super Mario World (Unl)
GameHacking.org | Super Mario World (Unl) [a1]
)
I don't know the game code of Magic carpet 1001 (Don't even know if the game was deleted from the list with all its codes)

I hope you can fix the issue of Unlicensed games not appearing in the NES code section, at least they aren't available through the links in the alphabet index.

Thanks in advance a lot. Looking forward to have this codes available for anyone who's having a hard time passing those games.
Greets! Cya!

PS: I can send you the "source" from which I tested this codes in PM so you can check them
