This is an UNIF PRG and CHR splitter and extractor, which was part of the test phase of my python tool to convert UNIF files to iNES files, for broader compatibility. Instructions : 1. Go to this website : https://tomeko.net/online_tools/file_to_hex.php?lang=en, make sure to uncheck the checkboxes and upload your UNIF file. UNIF files generally have .unf or .unif extensions. Press the "copy output to clipboard" button 2. Go back on this project and paste the clipboard content. It may take a while to load. If it only displays blank characters and that the button to answer disappears, it is normal, just press enter. 3. Your ROM will then be splitted in banks. You can also have an headerless iNES file at the very bottom of the output list, alongside the full PRG and the full CHR.
This version is fully functional and was tested with : Zelda (ES-1096)(Ch)[!] "塞尔达传说-三神之力" 45-in-1 JY-120A
