Current guest captures were regenerated on October 22, 2026 from the working-tree JavaVCPU/JV-DOS bytecode on disposable disks. They show the actual 256 by 256 palette framebuffer, enlarged exactly 3x to 768 by 768 by the headless regression runner. No host window borders are included. The normal Swing display scales to 800 by 800.
