Can you post the state file here

Yup you have encryption on as I suspected.You need to turn encryption off.

@Ghost In nestopia itself.

Make sure use internal compression is unchecked. 
 

Well, thanks for looking into it at least. Appreciate the effort. 

Downloaded the vanilla version and could not duplicate the failure. 10 times in a row the computer DID NOT kick an onsides kick. 

Yes…

SET(0x22117, 0xEAEAEA)
 

Yes…

@Tombor its doable but not a simple fix. This would be a complex hack that requires re-writing the playoff logic. And possibly the memory structure for saving the playoff teams

I think I had dug up that post before in a search but mus not have scrolled to the bottom or something. Dumb of me.

Thanks man. You confirmed my thought that the last byte had to be a combination of pallete and overlay. And you got into my next question of where the logo palletes are located. Not that it matters all that much. More info to add to the hacking guidebook.

Its faster to skip the halftime show rather than remove the graphics. I assume that would be fine @rkrenegade31

Try this rom out. This is just the OG rom. These are the hex locations to adjust to change the injury rate. 
01= 1/256 chance of injury
00 = never injured
FF = always injured (unless no more subs)

 
99% sure I fixed the problem of the previous hack where it would use the starter position (QB, RB1, RB2, WR1, TE1) instead of the actual roster ID (RB3 etc)
custom_injury_rate_test_rom.nes

So far so good
 
 

I've ran about 20 games and so far so good. Its gonna be a fun mid-season tourney where all fumbles and losers move on, Ill make sure to post about it here on Tecmobowl.org. Should be alot of fun. Thanks again bru!!!

Lots of different ways to do this but this should be the simplest since its just one byte
 
SET(0x258FE, 0xA9)
 
This changes this from loading a variable in memory to loading an immediate value that will make the routine branch to the no onsides exit)
 
I didn’t test this so let me know if it works.
 
This doesn’t apply for  skp vs skp games.
 
 

Yes, there is. Post something when i have time

This is the concept I came up with a while back to deal with variable number of teams. Easier to modify to have any number of teams.
 

Rankings are a bit off. Was doing this quick just to make something.

See examples of helmete and team data text. @JJT did the helmet graphics

@SBlueman It takes rearranging where the team names start on the team data screen. As well as moving the conference  name over.
 
But you will also have a problem on the blue screen stats page because there is a 10 character limit. The only way around that is to use small letters instead of large ones for  the team mascots on the blue screen page.

It requires a different trick because the name is too long…

This will skip past the yardline check and always set it to the twenty. 
 
P1 side:
SET (0x24502, 0xEAEAEAEAEAEAEAEAEAEA)
 
P2 side:
SET (0x24C8A, 0xEAEAEAEAEAEAEAEAEAEA)
 
I didn't double check this but it should work
 

This fixes the bug of the game always loading the worst avoid kick block value no matter what the kickers avoid kick block skill is. Found here: http://tecmobowl.org/topic/64764-big-buggame-is-always-loading-the-worst-avoid-kick-value/

 

 

(SET 0x293E1, 0x8D) 

(SET 0x293EB, 0x8D)

(SET 0x29487, 0xAC)

 

Thank you come again. 

Hello all, 
 
Over a period of years I managed to reverse engineer the entire Tecmo Super Bowl game into 6502 assembly source code with every piece of code documented and every variable labeled. There was a potential project in the works with said code but that project looks all but dead now. Because of that I am targeting the 30 year anniversary of TSB as the date I will publicly post all of the reverse engineered source code.
