@koekie...i just wonder why you are using notepad++ which has more feautres than notepad but you can't even save file to .pnach?
shortcut if u can save as .pnach directly :
1.save it to any kind of files.
2.from your windows explorer highlight your files.
3.press F2, and change the name. (e: Your CRC.lol to Your CRC.pnach...)
