When dealing with the Gameshark 5.0 PSX ISO, you will encounter issues. Here is how to solve them:
| Problem | Solution |
| :--- | :--- |
| ISO crashes on boot (black screen) | You have an unpatched ISO. Find the "No Dongle Crack" (search for Gameshark 5.0 No Dongle.bin). |
| Codes don't take effect | Ensure you entered a "Master Code" first for that game. Check that the region of the code matches your game ISO (NTSC-U vs PAL). |
| Disc swap fails in emulator | In DuckStation, eject disc, then change ISO, then insert disc. Timing matters. Wait 2 seconds. |

| ISO size is wrong | A proper rip is ~200MB (Mode 2/2352 bytes). If it's 10MB, it's a stripped "trainer" and likely broken. |
