Good news everyone Zelda II - The Nightmare of Ganon has been added to RetroAchievements.org with 45 achievements I made.
If you are going to play this romhack head over to retroachievements.org turn on Hardcore mode & see how many achievements you can get.Play with Retro Achievements:http://retroachievements.org/Game/11689
It took me a couple of days but I just finished a Hardcore Mode full run of the game and everything worked as intended all the achievements popped up at the right time & none popped up at wrong time.
Also I had no issues with the romhack I can say now it's been thoroughly tested and it's working great.
This game is really difficult & I had Game Over alot on my way through on Hardcore Mode, but as an average Zelda II player If I'm able to complete the game without savestates you can't say this is a "savestate hack" & too difficult. Keep at it, hang in there, tough it out, don't get frustrated, don't give up & eventually you will get better.
