Attempting to use a mac_qfb_driver for more different resolutions?

[brunocastello]

Describe the issue
I am attempting to use the following rom as outlined by the said rom dev: https://github.com/SolraBizna/mac_qfb_driver

However I am getting the Property 'q800-machine.fb' not found error. Is there a way we can find to make it work, so we can get the Quadra 800 to drive more custom resolutions? I am personally aiming for 1440x900 here

Configuration

• UTM Version: 4.7.4
• macOS Version: MacOS Sequoia 15.7.3
• Mac Chip (Intel, M1, ...): MacBook Pro M4 Pro 48GiB/1TB

Edit: I should add that I have a working quadra 800 vm with stock configuration, running MacOS 8.1 at 1152x870x8, the max possible resolution with the default display.
