A prototype of the original "The Legend of Zelda" for NES has been found and preserved

Another video game prototype has been found and preserved, and this time, it's none other than the game that spawned an entire franchise beloved by many, the very first "The Legend of Zelda" for the Nintendo Entertainment System.

The prototype seems to have been found by people from the Video Game History Foundation, with the director and founder of the foundation itself, Frank Cifaldi, being the one that released the prototype for research and preservation. The prototype was found in a yellow NES cartridge, with a simple label with the message "NOA COPY 2.23.87" "THE LEGEND OF ZELDA" in it. According to the label data, the prototype dates back to February 23rd, 1987, which predates the official release for the NES by 6 months.

Twitter user MrTalida started work on a comparison between the v1.0 official release of the title against the found prototype, with the prototype has quite a bit of differences in several parts of the ROM's data banks, which mostly seem to relate (at a first glance) to actual ASM code from the game according to the game's data bank structure.



So far, the only difference MrTalida found has been a glitch where Link gets stuck into the lower part of the screen whenever Link exists a door or a cave:

It's important to note, however, that despite this being a prototype, and going by the time stamp of the prototype, this seems to be Nintendo's initial programming test case for an FDS to NES conversion of the original Famicom disk system release of the game in Japan, which was originally released an entire year prior to this prototype's date, back in February 21st, 1986.

Any plausible differences and (most likely) glitches that could potentially be found within this prototype could very well be attributed to beta code being tested for the conversion of the game from disk to cartridge.

Oh look, actual game preservation that isn't just speading the ROMs of decades old games that have long since been preserved, I sure do hope that this won't be the last one for several months that actually get any decent news beyond Hidden Palace/TCRF and isn't used over the same bunch of ROMs that everyone and thier grandma has on thier computer's hard drive the next time a ROM Site goes under.

This is interesting. I know we've found earlier prototypes, such as the 12/28/1985 FDS prototype, but it may give us some insight into the FDS to NES conversion process.

    @BigOnYa, the character has the health behavior
  • BigOnYa @ BigOnYa:
    I know you have to create a health and health max variable. Then there is a calculation you use in code to subtract width size of the health bar. Google few vids.
  • Xdqwerty @ Xdqwerty:
    @BigOnYa, the "greenflatbar" is one of the preset health bars btw
  • BigOnYa @ BigOnYa:
    Yea you can use any bar/sprite. It will just change the width. Ok good luck and have fun. I'm off to go shoot some pool at the bar. Talk to you later.
