I created the Crosstie for the Jogobox version of Hydorah. Simply run the CrossTie and it this will download and install Jogobox into Crossover. Make sure while installing Jogobox, you click "advanced" and change the installation path to the "c:", so the program will be installed there (instead of in the local settings), this because otherwise the key input will not work in DOSbox. so don't forget this. When installation is done, run JogoBox and search for Hydorah and install and play. When the game launches you have to press "f4" in the "screenmode" so the screen will be in "full screen proportions" this fixes the glitch in the bottum and Top. Now you are ready to play!
Note:
Sound FX does not work ingame (shooting sound/explosions), the rest works fine. You don't even notice it is missing.
Have fun!
