In order to avoid request threads from spawning here, I am going to add some 'tips' (rule is a way too strong word imo, and everything is covered in the Universal Rules
THE SPRITERS RESOURCE GUIDE
This section is for your general doubts in sprite ripping. If you want to make custom sprites, go to Sprites and Pixelart
If you want to submit sprites, go to the Submissions
section and make a topic in the right place. There are guides that will help you on the way.
REQUEST THREADS WILL BE LOCKED ON SIGHT AND THE OP WILL BE WARNED.
There is a reason newcomers can't post in the requests section of this site. There is a difference between asking for help and flat out requesting.
Questions concerning how to rip sprites should be asked in the Ripping Questions
after using the search function and/or Google etc.
Thanks for reading!
