Difficulty Differences
The Japanese version allows the player to go through all nine stages on any difficulty setting, whereas the English version restricts the game's length on the lower settings: PRACTICE ends the game on Mission 3, while WARRIOR ends on Mission 8, leaving Mission 9 accessible only on SUPREME MASTER.
Continues are available by default in the Japanese version, whereas the English version requires the player to enter a cheat code at the GAME OVER screen that changes after every third stage. After choosing to continue, the player will be taken back to the main menu and will be allowed to change the number of players and difficulty setting before resuming at the last stage they left off. The length restriction will still be in effect after entering the continue cheat. This means that if the player lowers the difficulty level to PRACTICE on Mission 4 or above, the player will be warped back to Mission 3 instead. Likewise, lowering the setting to WARRIOR on Mission 9 will cause the player to continue the game on Mission 8 instead.
Enemies seem to be more aggressive and have more health points in the Japanese version's DIFFICULT setting than they do in the English version's equivalent setting of SUPREME MASTER.

Will there be someone who would like to restore the difficulty of the Japanese version on the USA games.
There are 2 solutions either there is an English translation on the Japanese version or someone creates a hexadecimal code for the USA version which will potentially make it compatible with other Hacks.
