I had this same issue, and it appeared that the emulator was ignoring the ini settings. I was able to fix it. The issue was with my display settings, not the emulator. I have a NVIDIA graphics card and under "Display" ->"Adjust desktop size and position", I changed "Perform scaling on:" from 'Display' to 'GPU'. This fixed it for all games. It appears that display scaling settings were overriding the emulator. Give it a try!
