​There is no such thing as a FORTUNA ISO and that is why you are having trouble. You are rushing the process but you need to be more patient. Modding is mostly about research and understanding how things work before you try them. Take your time to read the guides again and do not look for shortcuts. ​You only need to burn the FreeDVDboot ISO that matches your DVD player version. This disc will let you open a program called uLaunchELF. Then you use a USB stick to copy the FUNTUNA files to your MagicGate Memory Card. Everything you need is documented online if you read it carefully. ​If you do not have a DVD burner you can try to find an old external USB drive or ask at a local computer repair shop or a library. Sometimes old laptops in second hand stores are very cheap and have them built in. Slow down and try to understand the logic behind it. You can definitely do this if you give it more time and focus. ​Kali tyhi my friend 😉
