Is it able to download the nopackage Arch Linux NTSYNC CI version or nopackage Arch Linux CI version?

Is Valve xbe nopackage based on WINE10?

You can download various different Proton-tkg versions (and Wine-tkg outside of Steam) by enabling Advanced Mode from the About menu.

NTSYNC support is only available in the main branch as of #517 and is not in a release yet. Support for nopackage Arch Linux CI is referred to as the Wine Master build in ProtonUp-Qt, it was implemented in #187 a couple of years ago and can be downloaded with Advanced Mode enabled.
