Optional alarm fix on spads level. I wasn't happy with the results so I'm adding it as an optional fix.
What does it do?
In original spads level the alarm button is black and without textures. I couldn't find a better solution and since I'm not an expert I just moved the texture further from the door and moved the alarm a bit further as well since that was the only way I could figure out how to fix that. There're people working on really good HD upscale with use of different upscaling techniques and they fixed the blank alarm better than me so when it gets officially released You'll probably want to use that.
