Me and Daily as well as presumably all Windows 10 + OBS classic users have another problem, this:
OBS classic cannot capture window borders correctly on Windows 10. With many of us religiously avoiding monitor capture due to alt-tabbing or purely out of somewhat justified safety, or as with me, regularly moving windows around, this poses a pretty large problem. The only workaround for this is to first manually crop out the excess glitched border to the side of the window, and then only ever start a recording, stream or anything while Gambatte is the focused window. OBS is also fully unable to capture anything that changes in the title bar. Which means that you'd have to hard reset when switching roms, and restart your stream to make OBS work with it again. Daily also argues that it makes the title bar as useful as an overlaid screenshot of a title bar. I won't elaborate on that because I'm rather indifferent to the argument, but it is something worth considering.
I can also not switch to OBS Studio with a window capture plugin, for example, as studio is outright missing many of the important features I use.
Lastly, it also completely eliminates all possibility of playing in fullscreen, which kinda ruins the idea I had of having the game fullscreen on my second 4:3 monitor while having everything else on my primary, and I'm sure some other people (probably not too many though) also would find this annoying.
I wasn't opposed to the rule at first. It shits up stream layouts a bit blabla nothing large, but it's turning out to actually be a large inconvenience for many, where it was thought that it would not be. The main point of the rule is that you won't have newbies coming around and running on VBA, and it is otherwise very much a 'we trust you not to be a cunt' rule, as it is super, super easy to fake title bars, to the point where anyone who wants to cheat will still cheat.
My personal suggestion is a less inconvenient 'we trust you not to be a cunt' rule in the form of mandating having your emulator listed in some on-screen text. Nothing large or obnoxious, just some small text 'Emulator: Gambatte' 'Played on Gambatte' 'BGB GBC emu', whatever fits. This accomplishes the same core functions as the title bar rule does, by weeding out uninformed newbies, while it doesn't do less against cheaters, as adding some text to your layout is exactly as difficult as pasting over a title bar, and it has none of the downsides that the title bar rule does.
Perpetually lazy and uninspiring.
