Download and run

Download MagSID-Editor-v1.51-win-x64.zip, unpack it anywhere and run MagSID-Editor.exe. There is no installer.

• Needs Windows 10 or 11 (64-bit) and the .NET 8 Desktop Runtime for x64.
• The exe is not code-signed, so Windows SmartScreen may warn about an unknown publisher: More info → Run anyway.

What's fixed in 1.51

Menu → Load and Play .sid now plays tunes driven by a CIA timer. Before, such a file was refused with "The tune asks to be driven by a CIA timer rather than once per frame, which this player does not emulate."

• A PSID song whose speed flag asks for CIA 1's timer has its play routine called at the rate the tune sets in $DC04-$DC05 — read again after every call, so a tune that changes its tempo is followed — or at 60 calls a second, the KERNAL's own setting, when it sets none.
• The song length, the loop point and WAV/MP3/FLAC export use the same rate. Summer of 64 (Kristian Myklebust, Offence 2013), for example, runs at 100 calls a second and loops after 1:31.

Everything else is as in 1.5.
