You likely need a headerless version of the game file that is required. This tool can remove the header for you.
The following are known valid CRC codes for the required game file.
70080810: Metroid (NES)
4DE6A02B: Metroid (NES) (Metroid (U))
ROM info for the file you provided:
- Filename: {{file.name}}
- Headered: {{isHeadered | yesno}}
- CRC32: {{crc | upper}} (headerless: {{calcCrcHeaderless | upper}})
- Filesize: {{file.size}} bytes ({{parseInt(file.size/1024)}} kbytes, {{parseInt(file.size/1024/1024)}} mbytes)
- {{genError()}}
- This seems to match.
- The file you selected looks like it could be a compressed file.
- If it's a
.zip, your operating system should be able to extract it by right-clicking.
- If it's a
.7z, you'll need 7-Zip (which is primarily a Windows application) to extract it.
- If it's a
.rar, you'll need WinRAR (which is primarily a Windows application) to extract it.
