⚠️ The #1 Reason Patches Fail: 512-Byte Copier Headers
If you patch a Super Nintendo game and the screen stays black, you encountered a Header Mismatch. In the 1990s, backup copiers (Super Magicom) added a useless 512-byte header to the start of ROMs.
Exact multiple of 1,024 bytes (e.g., 3,145,728 bytes = exactly 3.0 MB). Modern No-Intro standard. Required by 95% of modern translations.
File size ends in 512 bytes extra (e.g., 3,146,240 bytes). If a patch was made for unheadered ROMs, applying it here corrupts the code execution.
