Hello everybody, today I will be showing you how to determine your Secret ID in Pokemon Heart Gold or Soul Silver. You can also hack your game using this method, but I won't go into detail about that. 1. Go to your NO$GBA BATTERY folder and copy your save file elsewhere in order to back it up in case you make a mistake. 2. Open NO$GBA.ini in Notepad, and scroll down to the line: SAV/SNA File Format == Compressed ...change this to: SAV/SNA File Format == Uncompressed ...and save the file. 3. Open No$GBA (make sure your save type in NO$GBA is FLASH 512 kbytes) and continue your game. Save the game, and quit NO$GBA. Check the size of your save file in the BATTERY folder. It should be over 500KB (mine was 512KB). 4. Download the following program. You will use it to convert your save file: No$GBA --> VBA Battery Converter To use it, click the "Configure" button and follow the instructions by clicking on the buttons in order. In the text box named "New .SAV File" enter a name for the new file you will make. Now select your Pokemon save file and press convert file. It will create a new save file with the name you typed in. 5. Now open up your Pokesav program for Pokemon HGSS. Click the button that says "open", and select your new converted save file (the one you made in step 4). Your ID and SID should appear in the text boxes corresponding to each. That's all folks! If you have any questions/concerns, please post a reply.
