Verify that settings are saved on exit (ensure "Save settings on exit" is checked in the settings menu).
Here is a development piece focused on setting up, testing, and optimizing this specific WIP build: Development Report: puNES (WIP D3D9) Optimization Target: puNES (Qt-based NES/NSF emulator). Version: WIP (Work in Progress), Windows 64-bit. Backend: D3D9 (Direct3D 9). Environment: Windows 7/10/11 x64.
This emulator allows for precise synchronization, but extremely high accuracy can demand more resources. 5. Immediate Next Steps Use Alt+Q to properly shut down the emulator. EmuCR-punes64.wip.d3d9 (4).zip

Test with the latest WIP changes in the puNES GitHub repository . To make this piece more useful,
Compare PAL/NTSC behavior in specific, notoriously tricky games (e.g., games using high-frequency bank switching). Backend: D3D9 (Direct3D 9)
NTSC filters (Composite, S-Video, RGB) can sometimes narrow screen width unexpectedly in fullscreen; try switching to standard scaling filters like hq3x or xBRZ if display issues occur.
