Thank you very much for your opinion.
I used the @herb_fargus hint, to take screenshots
1.1 About psp system, I put as playstation portable, and psx only as playstation. Only if it is something of resolution to have deleted the "portable" of the system logo
If you take a look at github, the file is correct there
Try to download the image of the psp logo again and put it and see if it corrects. If this is the case I create a new logo with the brief writing and solve the situation, I put "Playstation Portable" because I found it more interesting that way
1.2 In relation to the pc engine. I made the separation of the name of the system with Japanese and Western model name
I will correct the logo written "tg" for "TurboGrafx".
I tried to follow a pattern according to the documentation https://github.com/RetroPie/RetroPie-Setup/wiki/PC-Engine
If so, try to access your es_system system file and change the system theme
1.3 About the CPS system, I put it in Roman numeral because usually in the logo arts it is used that way. I thought a lot to put conventional numbers 1 2 3, but I ended up opting for Roman numeration, I'll test with a new logo to see if it gets better
2 In my case that was the intention, remove information let's say nobody reads. And leave only the name of the game cover and the video preview. Since I also left a lot of empty space on the screen, I honestly did not find a better way to fix it. I will test using the array of games list more in the middle of the screen to see how it is
3.1 That part I sincerely thought a lot about it, in showing or not the next logos.
Showing the next logos, it does not mix very much with the theme of pipboy, because it is a command line system.
About the "blurred" effect on the game selection screen, I thought I'd implement something like that, but unfortunately I could not do it. I ended up getting only in the list of games, which I particularly enjoyed the effect.
I will try to give a researched and try to update the theme with this, it will be much more attractive with this effect
I agree with you, my theme got pretty good for the handhelds, but the way I did, I say resolutions, settings etc etc probably will not work properly, even though I do not have screens of other resolutions to test this theme, unfortunately I only tested on the 32 inch tv I have
