ca0ss/ToolOPT6-Calculator — reverse-engineered prompt

Build me a small Windows desktop app for LG WebOS ToolOPT6 settings. I want to type in the decimal ToolOPT6 code from my TV, pick the matching TV series, press Reverse, and see the current hidden menu choices shown in normal labels and drop downs. Then I should be able to change options like Dolby Atmos, PVR and Time Shift, DVR Ready, WiFi Bluetooth, Motion Remote, Energy Star, adaptive dimming, Sound Mode, EDID, WiSA, and the other ToolOPT6 flags, then press Calculate to get the new decimal code to enter on the TV.

Please make the interface simple and safe, with a big warning that this can mess up the TV and that the user must copy their original code first. If the code doesn't match the selected TV layout, show a clear error instead of guessing. Include a Help button for figuring out series compatibility, and make it easy to add more TV encodings later from test data.
