This is the address for editing signature skills of the player you are currently editing whatever game mode 11DD67C 8 bytes in cheat engine (in green). I used this address to edit mycareer signature skills as well as my teammates'. To have the Lebron coast to coast or gatorade perform pack or randomize assist bonus or offensive awareness bonus, just change the value to any 19 digits numbers, or view lebron's signature skills or input 9000000000000000000 for the gatorade perform pack for any player. To find the address in roster.iff, scan the value of the signature skills of the player in cheat engine. the rest is trial and error in hex workshop (except players who have unique set of skills like Lebron). If you just want the signature skills for mycareer and not roster.iff, which is easier, cheat engine is all you need. just scan the value of the current signature skill of a player. Change it using the readable address, scan the change you made. An address starting in 0CXXXXXX will show up. Play mycareer and change the address to the value you want. Same process for attributes, coach profiles, play style and tendencies.
Another important address is 11DD5CC 4 bytes for play type and play iniator. Try to edit the play type of any player to find the value of the play type you want while viewing this address in cheat engine. For editing roster.iff, it is much easier if you already found the address for signature skills. For cheat engine, scan changes you made to find an address starting with 0CXXXXXX.
Coach settings addresses and tendencies can be found and changed through cheat engine, hex on steroids names ratings profile and hex workshop.

viewtopic.php?f=153&t=92732 Coach profiles addresses can be found and changed by trial and error in cheat engine, 4 bytes. Readable addresses (in green) are not working in editing coach profiles. If you find an address starting with 0CXXXXXX, that's the one. Anyway, Just change the coach profile to a percentage and search changed value, try to shift the cursor and scan unchanged value. Repeat the process and you'll find the address for any team you want. Then, reset roster to find the original value for example of the offensive tempo, fast break, and help defense. Save the value. Change them to 100%, save the value again. Go to Hex workshop and find in roster.iff the original value in 4 bytes. Change and save the value of the coach profile addresses like I did. Trial and error again. Viola, Super coach is in.
Tendencies can be edited by finding their signature skills first. Using hex workshop, skip the many zeros you notice in the memory addresses. Then, you'll find the attributes in the order in Hex on steroids a total of 42. I just press the right arrow key 41 times from the start of the attributes. Here comes the tendency values. A total of 58 values and I did the trial and error to know what comes first. I'll save the work for you
