>>>I know nothing about photoshop so i dont know if its possible to make one with a glass screen but without the glare in the image.
The main problem with this is that the glass overlay has the reflection baked into it, so separating the two would be a real pain. Plus, you then have one major problem in that, Glass itself is transparent and to give the impression of a glass screen there has to be some indication that glass is present in the image - such as a light reflection or similar. The hardest part for me is getting the subtlety right. Too much and all you can see if reflection getting in the way of the game, too subtle and you lose the effect. The 1084S monitors above are at 100% transparency because the layers are just flattened without alpha, in Retroarch the alpha is around 45% so the reflection is only slightly visible.
I am lucky here because I own lots of real hardware. NES, SNES, Megadrive, C64, Spectrum, Amstrad, Atari, etc… and lots of CRT monitors - Philips CM8833 Mark 1 and 2, Amstrad CTM644, JVC TV, Sony Trinitron CRT . So I can take photos of machines running on real hardware and observe characteristics like reflections, brightness, colour, etc… and then try and create that exact moment in Retroarch. What I would love to see is animated backdrops behind the emulated CRT, and the effects of the emulated CRT screen expanding outwards towards the edges of the TV - such as the flickering. I will have a play with the retro tv overlay and see what I can do.
satoso, I have no plans to create PVB/BVM monitors. There are not many quality, hi-res screens of these monitors on the internet, especially looking face-on.
