The design section acts different than a true pointer. The first byte is checked for if >x80, then >xA0, then >xC0, then >xE0 with each moving to a different branch of code. So when the design starts with xCC, the branch of >xC0 and <xE0 is ran and that part of the code subtracts x20. When the design starts with xB0, the branch of >xA0 and <xC0 is ran and that part of the code keeps the value intact. Short answer without a lot of details but hopefully that helps clarify why.

The entire code is in the rom from the following link. Its been a long long time but following the notes should help.

Its been a long time but I believe everything was sent directly over email.

Best bet would be to see if TecmoTurd still has the assembly code that I sent him. I'm 99.9% sure I lost it when my computer died a few years ago. The amount of code compared to Tecmo Super Bowl is extremely small.

Switching Individual Teams into different divisions
jstout replied to Tombor's topic in Hacking Documentation
It would be a ton faster and cleaner just to swap the full rosters and change the names and logos to match. All that is really simple. -

Holy cow Bruddog. You are still working on those files I created like a decade ago. I'll be really interested in seeing what you created in all this time.

Anyone Care to Share hex info for Ken Griffey Presents?
jstout replied to Ian Jones's topic in Other Games
Nice work on the graphics. Its been almost 15 years since I messed with the game but I helped slim_jimmy7 with graphics in the past. I have no notes any longer but I can tell you the logo graphics are compressed in the game. Back then, I wrote a program that decompressed the logos and was able to learn many of the commands through a text output which allowed me to write the new logos by hand into the game with a hex editor. You'd have to ask slim_jimmy7 but possibly he still has a copy of my decompressor (if the code is still with it than it shouldn't be to hard to figure out from that). -
I appreciate the kind words from everyone. I actually stopped by to find out what happened to Gridiron Heroes and ran into this thread. I feel a bit bad about disappearing from here. A few years back, I had a hard drive crash where I lost countless notes. Then I basically ran out of ideas for fun hacks and slowly stopped popping by. I spent most of last year with a computer that would blue screen randomly a few times a day so doing anything became a massive headache. But I do stop by now and then but usually not signed in.

What data are you looking for? I use to play Tecmo NBA Basketball as a kid but it was too easy vs the CPU and later moved on to playing NBA Live 95.
-
Yeah, I'm doing fine. Bruddog is correct that its Games Played. The "Adjuster" part is if you had some scrub that say played 1 game and had a star performance then you could set this value higher to cut down the final value to a more logical score.

New Base NES ROM (32-Team Original TSB Gameplay)
jstout replied to GameplayLoop's topic in ROM Editing Discussion
You guys might be way over complicating the mini helmets. Detroit already uses the grey color so just remove the special byte that places the black facemask and instead use the standard grey facemask. Cleveland has Black for the dark brown so if you recolor the tiles it should be good. No need for changing pointers and such. I got the following in just minutes. base-2017-update.nes -
The evolution of reverse engineering TSB
jstout replied to bruddog's topic in ROM Editing Discussion
That is highly impressive Bruddog. The time it took for me to get the original disassembly was a huge pain by itself. -
I don't remember all the changes but finding them should be extremely simple. Set breakpoints for offense of reads to: Special Teams/Formation Pointers (11 Pointers): $A000-$A1E3 Play Pointers (11 Pointers): $A400-$ABE7 Extra Pointers (12 Pointers): $AE00-$AF7F Set breakpoints for defense of reads to: Play Pointers (11 Pointers): $A000-$B5E9 Extra Pointers (12 Pointers): $B600-$B77F After a fast check: (remember your extra pointers need 8 pointers for the 7 players like my CIFL rom had) The pointers needs the X index changed from x0B to x07 at x2573B and at x25810. Could be it or even a few more spots but you should be able to figure it out with breakpoints.

Attached is a rom stripped down to only display the TSB Game Field with the source code. I'm only posting this since it might make it easier for someone to edit the game field. Controller: Pressing left and right will make the field scroll and pressing up and down will change the crowd animations. Animations are 0 = cheerleaders and no crowd movement, 1 = cheerleader celebration and crowd movement, 2 and 3 = cheerleaders and crowd movement then the next animation cycles back to 0. The game field data is located at x2010-x2B38 and needs to be pasted to x2C419-x2CF41 in an actual TSB rom. The graphics would need to be copied over as well. **Note the rom does absolutely nothing but display the game field using code from the actual game. GameField.zip
