After some effort, i manage to get the gamepad and emulators to work.

but it turned out not as fun as i though. those games back then were insanely hard to play.

contra: just one man vs an entire army, get shot once instant death
ninja turtles: one ninja vs infinite amount of minions (seriously!), press attack button until thumb also sore
megaman: i shoot boss soooo many times, he lose 1% health, boss touch me one time i lose 30% health, did i mention boss health bar is twice longer than mine ><
castlevania: the game in slow motion one, sweat. also one touch by enemy instant death
mario: keep falling into holes, floor damn slippery, touch by enemy also instant death

i'm beginning to see a trend, those games back then, they wana earn money by players insert "coins" real money after they die to continue. thats how the earn $$ so must make the game very hard to play and very easy to die.

kids these days are less patient, lazier, so modern games difficulty is much easier,
but have to use real $$ to buy weapons to make the game less repetitive and fun.
