Yes there are dissaambler prgs out there and they maake it easier tosee how a bit of code works, funny how many people think that reverse engineering was invented on the PC when Commadorians have been doing it for years.
As for is theree a special part/place to go to in a game I cant explain tottally I just examine everything I possibly can, certain areas are reserved for set things / music / gfx / prg code, and sometimes it works.
Although Ive lost many hours that I dont have much to show for.
Take C64 music,its easy enough to know that most of it starts at mem location $1000 that is to say where it initialisess, then say it plays at mem location $1003, that part is the easy part, but now you have to work out exactly where it ends, if U miscalculate it, you mightt miss getting all the instruments, which can often be found near the end of the music, this all also depends on what sort of music-player the tune was made in, in the first place,experiment.experiment and yeah experiment
I use my AR cart to rip music,I also use it to hack into games.......... _________________ http://noname.c64.org/csdb/scener/?id=1971 |

Interesting post
SID chips are quite sought after in the electronics community. I have seen people interface them with a microcontroller and make their own music player out of them. It's quite impressive.
I was going to give it a go one day (when I get around to it) It would be great to have some SID tunes playing in the background to one of my little LED games.
I would have really liked to have been born a little earlier than 1982. I would have liked to perhaps have been the age I am now when the C64 was in it's prime - no doubt i'd be fidling around with code just as you did.
Man that would have been fun! |
