1. SNA files are model-dependent. Once a snapshot is created for a 464, for example, it can no longer be used for another model, since the file itself captures the systemÂ’s identity
2. SNA files are emulator-dependent. They are of little use to anyone using another emulator
3. For the above two reasons, I do not want to contribute to saturation of SNA files on the web, when much better alternatives (ROM, tape and disk images) are readily available
4. Treating SNA files as regular image files means supporting save states for the SNA file. This just seems recursively silly
