Cartload: memory card backup from the browser
Hi. One of my hobby projects is cartload.org. It’s a browser app for backing up cartridges from various systems with a GBxFlash and (optionally) Analogue Pocket adapters.
Recently, I added support for backup of PS1 memory cards with the Sony Memory Card Adaptor (CECHZM1). You can back up a whole card to .mcr, or individual save files to .mcs. No support for writing data back yet, though it would be possible.
It uses WebUSB, which is available on Blink browsers: mainly Chrome, Edge, and Opera. This includes Chrome on Android, but not iOS.
I’m not totally sure I’ve implemented everything correctly. I’m pretty sure the .mcr dumps should be good. For .mcs, I support non-contiguous files and broken sector remapping, but I don’t actually have applicable cards to test with.
Currently the interface needs work. The app was originally built around backing up cartridges, which always have ROM data and sometimes save data. But, if you have the adapter, and need a quick backup, give it a try.
