Newbie to hex editing?

I have something im trying to do, and i cannot seem to follow the directions, can you guys help?
heres what directions say:

Confirm “key ability: 10” displayed in lower left corner
5. Close winrw32.exe
6. Open KEYGRACE.IFO with HEX editor
7. Place cursor on 0A (08)
8. Goto EDIT and SELECT BLOCK or Ctrl+E
9. Make sure START OFFSET 8, END OFFSET 8, LENGTH 1 AND ON HEX
10. Change offset 08 from “0A” to “0F” then save for ability 15 and “14” for ability 20
STEP-7

my biggest question that i cannot figure out is:
then save for ability 15 and “14” for ability 20
i cannot figure out this part!

i had 3 other pictures but this site wont let me upload but 1

For hex editing, the instructions just say to change ‘0A’ to either ‘0F’ or ‘14’. We’re not sure what ability 15 or 20 means and you’ll have to ask in a forum that works with winrw32.exe.

While I’m not familiar with KEYGRACE.IFO or TCMs, it seems likely that you’re tweaking settings. My guess is that this is related to the values you’re putting in. My interpretation of these instructions is that you need to change the value at offset 8 in the file to hold a desired ability value. The hex value “0F” corresponds to the decimal value 15. The hex value “14” equals the decimal value 20. Presumably the byte at offset 8 stores the ability setting, so updating it to “0F” will give the ability 15 and “14” will give the ability 20. What that means, I have no idea.

For more information about how hex values work, you can see Wikipedia.
