Is there any way of translating ROMs If yes how

Yes. This is commonly done by teams, but also by some individuals. Basically, a ROM hacker use a hex editor to search for patterns to find words, like "sword." They then use these patterns to figure out what all the other hex codes stand for. Finally, they dump the text into a file, and give it to a skilled translator. The translator will translate the words to the target language, and give them back to the hacker. The hacker will modify the hex code of the ROM, and try to place the words back into the game. This is a very time-consuming process, and daunting if you've never done any modifications before. Fortunately, most teams make their translations public, so you can just download an IPS patch and play the game in your emulator as usual.
