This game was converted from SG-1000 version of BombJack, an old console from SEGA.
(That's why it has a big SEGA logo when the game starts)
I would like to Thank to Ricardo Bittencourt for teaching me how to port this game from SG-1000, and for making the loader program for me. No way I would be able to do this without his help.
I would like also to thank Daniel Caetano, which helped me out with my SN76489 emulator. He was very patient with me, even when I was asking VERY stupid questions ^_^
