Dragon Fighter – Fixed Version (Hack) Description:
“Now you can include a dragon at any time, without the accumulation a half of power-scale. Note: don’t turn on the dragon, if the power-scale is equal to 1, otherwise the dragon will disappear immediately.
Shooting special (fireballs) now is faster (hold B button for 2 seconds, instead of 4 seconds in original).
Slightly increased the life scale at all (except the last) levels.
The last level has become a little easier, allowing you to finally pass the last boss. However, the game hasn’t lost its level of difficulty, and it’s awesome.”
