ok so i have checked out those 4 and Robot i think is the best, even tho Xing ji wu si has good character design's the broken game play kill's it for me. Super robot just jumps its ok i guess and warship is just an night arrow hack that is birds and a bow and arrow? Cool that these games have been made tho. This got me thinking has there ever been a NES Robo Warrior/Bomber king hack? with new levels and maybe new bosses? And i checked the AVP nice code bootleg looks good enough to play, if the nes rom has been dumped maybe some one like pacnsac dave can translate it or any other better hackers. They could probably improve on the graphics and maybe make more levels and have a ending boss.
