Understanding FSK Issues

Typical FSK Opening Challenges

A8CAS Removed

You attempt to load your FSK file and get an error such as "%%os%% Can't Open The FSK File Extension". When this happens, it is commonly due to A8CAS missing in %%os%%. The typical path of opening your FSK with a double-click won't work because %%os%% cannot make the program connection.

Tip: If you know of another program that can open your FSK file, you can try opening it by selecting the application from the programs listed.

Outdated A8CAS

It is possible that your version of A8CAS isn't able to open your Atari 8-bit Cassette Image file due to incompatibility. Visit the SourceForge website to download (or purchase) the latest version of A8CAS. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.

Tip: Find clues on the correct software version by right-clicking your FSK file and clicking "Properties".

Conclusion: The majority of FSK file opening issues are due to not having the correct A8CAS version installed.

Associated Difficulties Loading FSK Files

Errors opening Atari 8-bit Cassette Image files can still occur even with the latest A8CAS software installed on your computer. Other FSK opening errors can be created by other system problems inside of %%os%%. Issues that aren't software-related:

• Unintentional removal of the description of the FSK file inside the Windows Registry
• Corrupt install of A8CAS or other FSK-related program
• File corruption affecting your FSK file
• Your FSK has adversely impacted by malware
• Drivers associated with FSK software need to be updated
