"The Legend of Zelda Optimum is an optimization patch for The Legend of Zelda. It converts the ROM to MMC5, and its graphics format to CHR-ROM.
This patch is to be applied to the English version, The Legend of Zelda, not the Japanese version, Zelda no Densetsu. This hack was only tested on FCEUX 2.2.2. It was not tested on other emulators. Please see readme for details.
ZeldaTech (Overworld Editor) and DungeonMaster (Dungeon Editor) have been tested to work with this ROM.
According to the author, this is now the most enhanced Zelda ROM to work with, and is definitely recommended to anyone wanting to hack this game."
