I’ve pretty much solved this anyways:
I am going to simply offer the following as components to be ticked/unticked.
1. JFLP patch (or whatever final patch we can come up with)
2. Widescreen
3. JFLP DLL, with a warning that it may be seen as cheating on some servers.
Any dacom.ini particular edits will be done post-install by after script.
I think that will cover most bases tbh.
Anything else you think I should add guys?
