What's New#

What changed in each release of C64 READY., in plain language — newest first. The version you are running is shown at the bottom of the About dialog.

2026.8.0 — August 4, 2026#

Better sound, and a way to get your work out of the emulator.

• A new SID engine. The reSID transistor-level model now runs as compiled WebAssembly and is the default, so the sound is the same as before but far cheaper to produce. Options ▸ Sound still lets you pick reSID JS or the older Legacy engine, and all three play at the same volume.
• Record what you see. A new RECORD button captures the window with sound to an MP4 you can trim in QuickTime or drop straight into a video editor. Works in Chrome, Edge and desktop Safari, up to 1080p.
• Master volume. A real volume slider, with MUTE folded into it.
• Disks you can write to. BLANK to insert a fresh disk, FORMAT to prepare it, then SAVE into it from BASIC. Deleting files works too, and a disk can be write-protected or exported back out as a .d64 file. It all runs through the real 1541 DOS, so a program cannot tell the difference.
• Tidier save states. Rename a state from the Load State dialog, and find it again in an alphabetical list.
• A sharper picture. The display is now sized in whole multiples of the C64's own framebuffer, so no scaling step softens a pixel. On a phone held upright it fills the width.
• A new Retro Vibes scene. An 80s bedroom, and a reworked IK+ Sunset built after the original game's backdrops.
• A welcome screen. First-time visitors get a short introduction with a teaser video instead of landing cold in the machine.
• A much smaller install. The installable app went from about 12 MB to 1.9 MB, and the documentation now works offline once installed.
• Fixes. Audio no longer lags after a keypress or when returning to the tab, gamepads work in the installed app, mouse and paddle inputs report correctly on an empty port, and the Android soft keyboard behaves.
