Month 2025-10 focused on delivering customer-visible improvements in WAGE and Mac GUI, hardening the audio subsystem, and improving debugging/observability across the project. The work spanned scummvm/scummvm and scummvm/scummvm-web, with emphasis on UI/UX stability, cross-platform Mac GUI enhancements, and script/data quality. Key features delivered include: 1) WAGE: Dialog system and volume controls — moved dialogs to the Gui class, groundwork for a custom MacDialog, and added volume controls in the About dialog with a beep on changes, plus a hardened rendering/drawing path. 2) GRAPHICS/MACGUI: MACGUI enhancements — split blitting and painting for MacDialog, support for MacDialog subclassing, and ability for MacDialog to override event processing. 3) WAGE: Audio routing and debugging — switch sounds to the SFX channel, mark the engine as SFX-only, and add sound-related debug output. 4) WAGE: Extend and refine behavior logic — additional comparison condition for WAGE. 5) BROADER stability and refinement — script decompilation robustness, LINGO keyword cleanup, and improved debugging outputs. Major bugs fixed include: 1) WAGE: Avoid simultaneous sound playback to ensure predictable audio behavior. 2) WAGE: Sound handling validation — future scheduling, empty-sound sanity checks, and presence validation. 3) WAGE: Detect premature end of bitmaps. 4) GRAPHICS/MACGUI: MacTextWindow stability fixes and event-processing edge cases (modifier keys, text blinking, scrolling flicker). 5) DIRECTOR: LINGO regression around clickOn and related keyword handling; plus broader cleanup to reduce noisy warnings. Overall impact and accomplishments: The month delivered end-to-end improvements to user experience and reliability: deterministic audio playback, richer Mac GUI capabilities, and stronger UI scripting scaffolding. These changes reduce user-reported issues, accelerate debugging, and provide a stronger foundation for further polish in Q4. The work also demonstrates breadth across GUI architecture, cross-platform concerns, and debugging instrumentation. Technologies/skills demonstrated: GUI refactoring and architecture (Dialog and Gui hierarchy), Mac-specific UI enhancements (MACGUI and MacDialog), audio subsystem hardening (SFX routing, scheduling, and debug tracing), LINGO keyword scaffolding and debugging, and improved script/decompilation robustness.
