Topic: taking ringcodes with a smartphone
Maybe my method can help you, because most of us have a smartphone and/or tablet nowadays. I am using the free and open source app for android "Open Camera" with it i can enable the flashligt mode so the light is always shining so you can position to the right spot where you can see the ringcode or a part of it. I have redumped only one PSX game and it worked there great too i have returned the game disc so i cant show you the example but i did it with a DVD-9 PC game so you can see what i mean. On the last two pics i have put my phone on a box so i dont have to hold it.
I used this with my old samsung phone and with the new one and it works on both, but i would also like to hear if that works for other people too so please give me feedback about it.
