    This is awesome to hear, thank you.  I really do appreciate your feedback!  I will be honest, I haven't looked at updating the editor in a while but I will look into this now that I know ppl are interested.  I too, loved Madden 98 on Genesis, as soon as the games went o PS1 I didn't think they played as well.  I remember a few years ago when I thought about playing Madden 91, 92, 93 with updated rosters, I was sure someone created an editor but was shocked to see no one had at the time.  So it was a lot of fun putting the editor together.

    Will definitely keep you guys posted on when I can get this working for Madden 98 player names..... 

    I did enjoy that 2017 rom you put together using Madden 93...I have always loved the early madden's the most as well as the N64 version. Madden hasnt been the same since.

  2. Is Madden 64 easily editable? I believe Madden 64 would be much better than Madden 98. I have never taken a look at the hex code of Madden 64 to see if its extremely difficult to edit to find the relevant offsets. For the Genesis, I always believe that 92-93 are the best Maddens then 94. Madden 96-98 are ehhh.

    99% sure they don't have the source code. Source code repositories and versioning weren't a thing back then. The code was probably kept on some computer or tape backup that was lost 20 years ago.

    One of my favourite games is the "Cataclysm" expansion from 2000 for the game "Homeworld." A few years ago they released a remastered version of Homeworld, but there's no Cataclysm expansion for it.. because they lost the source code.

    NASA taped over the original moon landing tapes, BBC taped over the original Doctor Who tapes...

    Hell I used to have my own code repository on a computer in my basement, and I have no idea if that thing works anymore or what the passwords were etc :P

    This is true, good point lol.

    If you disagree, then you need to check your butter packets.

    It's got a lot of great plays like: HB Sweep, and Run & Shoot.

    Also, the amberlamps runs over players if they're injured:

    Here's a game between me and the Duke of Earl '94, Dan and I from days of yore. 

    I love me some Tecmo, but I wish Madden was more celebrated in retro sports communities. 

    They're so much fun to play competitively.

    Agreed, these Madden games are the best ever made. Wish it had a proper season season mode just like the same wish I have for NHL 94.

    Hello All, 

    Im going to be using this forum to create a directory of all my roms I've modified and uploaded. But his will consist of new updates, old versions as well as future project notices. In addition, Ill be posting "How To" for each rom on how I created my version, or where I was able to find the details to modify in the rom.

    • World Series Baseball 98'
    • Tecmo Super Bowl 
    • Tecmo Super Bowl 3
    • Triple Play Baseball Gold
    • John Madden Series 
    • NHL 95
    • NFL Primetime
    • Madden 64 - N64
    • Blitz - N64

    You are creating rom updates for John Madden on the Genesis and Nintendo 64? That is beyond awesome including how-tos to find the info in the hex editor. This would be really great work. I see you already made NBA Live updated, I will check that out.

  6. I know there has been discussion in the player ratings forum about how various parts of the player ratings were broken down and weighted. My question in these older EA sports games, were the player attribute ratings implemented via a lookup table structure. So, if there is a breakaway in the third period or any period and I am Jeremy Roenick or Wayne Gretzky , the statistical probability is called upon a lookup table ( to look at the all player attribute info and the goalie info) to pull the probability value of scoring vs the goalie they are facing into the main algorithm. I heard many of these games implemented a pre-computed lookup table, thus eliminating processing time and tons of conditional case and/or if statements. Could anyone shed more light on this?

    Thanks!

  7. Hello:

    I appreciate the quick reply. I attached the ROM to this message if you could please take a look
    at the hex and TM, I would greatly appreciate it.

    I can easily change text and player attributes, but I need to be able to update the small
    black and images next to the player information. I am having trouble on how to do this.

    Things I have found out:

    By going through TM - hex offsets from 0012F600 to 0014BE00 produce items that I think are the images
    but it is not in the correct palette. I have the codec displayed at 4bpp linear.
    I am not sure if the images are compressed?

    Additionally, tried to test if those offsets that I see in TM are the same offsets in the hex and
    indeed there are, when I tried to change all the hex to zero, the images when running the game
    in Kega Fusion, disappeared completely.

    I have also figured out the hex code to correspond to each image:

    For example:

    Sampras = hex values 13 06 at offset 00028719
    Stich   = hex values 13 10 at offset 000287B7
    Edberg =  hex values 13 1A at offset 00028855

    Inline image 2

    So if I change 13 10 to 13 06 , then Stich would be assigned Sampras' image.

    I am guessing if I can display images somehow correctly in TM, then I could mimic the
    image editing process that NHL 94 has and I update the images similarly. But I have not been
    able to display the images correctly, nor I am sure of what size the actual player images are.

  8. Hello,

    So I know this is not a hockey question but I know there are people here who have vast experience of ROM editing for the Genesis and have produced very enjoyable NHL rom hacks. I am trying to do update ATP Championship Tennis for the Genesis. I have located where the images sit on the ROM, but I do not know how to extract the palette information (offset for the palette via the hex editor) from the black and white image. I know EA used a similar concept for the NHL series and was looking for help. I know how to edit the text and player abilities but I would like to change some of the images. I would appreciate any assistance.
