ROM Hacking

[olivier]

Hello.

I'm Olivier, a french guy, turned 35 and a huge fan of Classic Genesis
Sports. I've been following CGS since ... well several years, and have been both impressed and delighted by the hack on those good ol' games.

Does any information regarding how to hack the madden 92 rom exist (roster and uniform) ? Once upon a time I've retyped (instead of OCRed !) the wole Madden 92 roster stat (I might still have it !), I'm quite familiar with Genesis and 32x programming (check and may
have some time to put ... why not the '11 stats ?
But I really don't know how to do it. I've once read that the stats are "zipped" into the rom", so it' ain't easy to figure how and where.
If you tell me the "where", I would make the "how" and will give you the "what".

Cheers from France,
Olivier

Hi Oliver,

I just put the most recent four roms into a RAR archive and posted them for download, you can read the message in the Rom Download sub-forum here; gensports.proboards.com/index.cgi?board=downloads&action=display&thread=1619

As far as editing the Madden roms, for player ratings, etc, a hex editor is needed to edit the hex values to change colors, player ratings, length of clock and all sorts of other game attributes.

To get started I would suggest googling how to "Hack Sonic for sega genesis" or something along that line, and just look at the basics of how to change the number of lives, or the change some of the colors. All you need to know is the locations of the information you need to change, and it is easy to edit.

You can look at the forums on NHL94.com and they have lots of info on hacking NHL94 roms, which are similar to the early Madden roms.

With just a bit of understanding, you can look in the Madden2007 folder, there is a Guide to the Madden roms and hacking them.

I plan to do more roms, but my health has been poor in recent years, so I do not do as much as I would like. I would like to do a new NFL rom and new NCAA rom soon perhaps.

I am glad to see that there are people outside North America who are interested in North American football!
