Sorry, the Mediafire link for the Hex Packet Readme template does not work, so instead I will give it to you right here:
Make a new txt file and copy and paste the following into it:
Hex Packet Information
Arranged by Stickman
Hack by [Your name here]
[NTSC-U]
Directions:
1. Open hacksample.hex, hacksampleFIX.hex, and your smashbros_sound.brsar in your favorite hex editor (I use HxD).
2. Copy the contents of hacksample.hex by "Select All" (Ctrl + A) and then "Copy" (Ctrl + C).
3. Now in the .brsar, "Go to" (Ctrl + G) offset [sound location].
4. "Paste (overwriting current data)" (Ctrl + B)
5. Now copy the contents of hacksampleFIX.hex by "Select All" (Ctrl + A) and then "Copy" (Ctrl + C).
6. Now in the .brsar, "Go to" (Ctrl + G) offset [FIX location].
7. "Paste (overwriting current data)" (Ctrl + B)
8. "Save" (Ctrl + S).
9. Enjoy!
replace the words in brackets with the info that applies to your hack. Sorry for the inconvenience.
