The script for bios is called bios getter.Thanks. It downloads everything on the USB like it should (and filters out what you don't want) but you can't see any of the cores from menu, but you can see them if browsing file system on sftp.
Couple other things:
Is the normal update.sh also end of life?
Do you know what a good option is for getting BIOS files with downloader? Adding BIOS as a filter gets a few of them but not like PSX and MegaCD. I have them backed up but would like to find a way to easily re download them through script like before.
What's the correct way to download the scripts from the wiki? I grabbed from file viewer and saved the .sh to the mister. They didn't run. I had to roll back to some old ones I have saved.
