Holy cow.  Well done bruddog!

Thanks to Bruddog's reverse engineering source code, I can add the information for in-game subs to this post!
 
At x21FB9, the in-game sub order begins with 10 for the backup QB.
At x21FBA-21FC0 is the backup order for Running Backs and PR/KR in all formations (12 is RB3, 14 is RB4, 16 is WR3, etc.)
At x21FC1-21FC5 is the backup order for all Wide Receivers in the 3-wide and 4-wide formations.
At x21FC6-21FCA is the backup order for all Wide Receivers in the 2-back formation.
At x21FCB-21FD4 is the backup order for the Tight End/4th Wide Receiver in all formations.
 
 
At x21F99-21FA8 are the pointers for the 2-back formation subs, one pointer for each starting position, QB through PR. A9 9F points to x21FB9, AA 9F points to x21FBA and so on.
At x21FA9-21FB8 are the pointers for the 3-wide and 4-wide formations. You can see in this list 3 B1 9F in a row, one for each Wide Receiver.
 
So if you'd like to mess with substitution order, you can do so by changing these pointers for a single position, or change the order of the subs overall. I know this isn't that useful, but I thought I would add it for my sake at least since I do use it.

This is such a huge moment in the community, i can't wait to get my hands on it and see what I can make. Thank you so much to bruddog

Was hoping to push it out today but need to change/fix a few more things.

Set all bytes to 00 in the following locations. 
0x5C180 thru 0x5C18F  
0x5C1E0 thru 0x5C1EF  
 
These are sprites and not background objects like the remainder of the helmet
BEFORE FIX

 
AFTER FIX

Yea, a little background, I own an IT company (20 years running), My brother and I have been Tecmo bowl fans since it came out. He is a diehard Ram fan, I am a Niner fan, so the Everett vs Montana rivalry on Techmo Bowl was out of control lol
 
We are moving to design a website with full content management , that can automate league creation on the server side, and make things very user friendly. Once we have our "game plan" developed (over next month), I will run it by the forum for feedback.
 
Our assembly language guys are excited to dig into this.
 
 

The dynastyphile (tecmobowl.net) site isn’t being maintained anymore. The person who created doesn’t have the time anymore.
 
And it does have a few bugs and issues from what I’ve heard. Its not heavily used but a few active leagues use it.
 
Definitely doesn’t hurt to have another possible option if this is mostly a labour of love type of thing.

Still targeting some time in April…

Confirmed in the code agility value is definitely used when changing directions for a man controlled player, however it doesn't effect the qb for some reason. Or at least the QB doesn't use this code both behind the LOS and past the LOS. 
 
The table for offensive players is at 0x1d4FF in the rom
06 06 05 05 04 04 03 03 02 02 01 01 01 01 01 01
 
The table for offensive players is at 0x1d50F in the rom
07 07 07 06 06 05 05 05 04 04 03 02 01 01 01 01 
 
These numbers represent how many frames it takes until it responds to you changing direction. I made the values 20 = 32 frames = ~ 0.5 sec and it was EXTREMELY noticeable. Its like trying to change directions in mud. 

So of the two players who are currently in the WR1 and WR 2 spot on the field, one of them will have a chance to pause their route. 
 
I guess its supposed to be a hot route of sorts where you can make a quick throw to the WR. But this seems kind of annoying if you need them to them run a bomb
 
I haven't calculated the chance yet but the greater the reception skill the greater the chance the WR will stop. 
 
The table is at 0x18B37
18 = 06 rec skill value = 9.7% chance of stopping route
20 = 13 rec skill value = 12.8% chance of stopping route
...
90 = 100 rec skill value = 56% chance of stopping route if selected
 
Every skill increase = 3.1% additional chance of stopping route
 
So really the chance for the WR1 or Wr2 to stop a route on any play is half that chance since only one of them can get selected per play. 
 
I'm pretty sure  these percentages are correct.

Still targeting some time in April…

Hope is still alive…maybe April of this year.

More info figured out.
 
The computer gets a random amount of presses....
 
75% chance to get one press every 9 frames...

Weather has the same impact on player attributes as TSB 1.
 
The table starts at 0x18bb7 in the rom.    
0 = no change
FF = -1 to all all attributes but ms/ps
FE = -2 to all all attributes but ms/ps
 
S= snow, R= rain

In SNOW buffalo gets no penalties. In rain they lose 2 notches to ALL attributes but max speed and passing speed. 
 
TB is the only team not to get a RAIN penalty. 
 
 
These are quite massive adjustments. It would be like one team having their whole team in good and the other having their whole team in bad before even factoring in the actual conditions. 

Yes

Even more info on this
 
 
Player 1 takes 10 +30 = 40 frames to get up after slipping 
Player 2 takes 10 +30 = 50 frames to get up after slipping 
 
10 frames = ~0.166 seconds

Holy juice for NE. Lol For reference the 49ers are  345 on the original rom. The Colts are a 30. Average team around 200.
