So, well, I'm new and I readed the Getting Started section of this site, I downloaded a Link To The Past/Four Swords rom (GBA), a emulator and Tile Layer Pro.
So, I wanted to hack it, but everything I saw was just a bunch of random green pixels. I went out to search for some help, and when I got back, I selected the format and pallete to GBA, but everything I saw was just random colorful pixels. I tried to search for more help on hacking it, and I didn't found a answer I could understand.
So, my question is, did that happened because the file is compressed or because of another thing? Please help me!
