So, the CSV was just something I did to organize them all in the hopes to import them. I should have checked if it was even possible first, so scratch that.
Problem Statement:
Let's say you had 200+ games that launched from a variety of different paths (C:\program files\XXXXX\X.exe), batch files, etc. You wanted to load them up under a single category for ease .. so say Windows.
Is the best option to create a new XML that defines them each as a unique entity? Because I'm perfectly capable of doing that either with a PS script or just use an LLM to build it out for me using my CSV as the source file.
Ultimately, I have a crapload of unique stuff, some of the batches run windows games with custom parameters necessary, others run a special version of mame highly customized with 1 rom, etc. Its just easier for these not to dump them in raw and instead create them under 1 new category so I can keep the work I did years ago in place on these.
