I suspect the - VGX things to be some code of signature. As well Nintendo changed the Fire Temple music to something else in later release versions. VGX One interesting fact about the Gold Cartridge game is that the blood that streams from Ganon's body when he is hit by Link's Master Sword at the end of the game, is red, in all other versions, 1.1, 1.2, etc it's greenish. You can find out what version you have by performing the 'Video Gamer X Debug Code' which brings up a programmers debugging screen and it shows the software compilation date. This only works on version 1.0, but there are more complicated ways using the GameShark to do it on version 1.1, etc. There is a trick that allows you to play the game without Link's sword and it creates a pile of glitches and great cheats and tricks. Then came out a version 1.2 All gold cartridges are 1.0. Nintendo fixed a bunch of glitchs and bugs in first version. Some grey cartridges are as well, but very few, many more came out early that year in 1999 as version 1.1, which were all grey. The Gold Cartridge games that came out in November of 1998 are version 1.0. The game actually came out in software release versions.
