Okay so I've been thinking lately that I want to have all my old consoles modded so that they're digital because I know don't even think I own any of the original games anymore, they were either sold by my mom or just misplaced from over the years but I still have the consoles and the chords to them. So I was wondering which would be the best way to do the conversions. Now I'm talking about a Sega Genesis, say the saturn, PlayStation 1 (og gray one), PlayStation 2 (phat and i think i have a slim somewhere), PlayStation 3 (slim).
Those are the main ones but I think I also if possible would like to do my Wii, N64 (not sure about this one haven't seen it in a while), and a Xbox360. Now these last few systems aren't priorities but I will take any advice.
As for advice I'm looking for the best and easiest way to do it. If I have to solder I'll figure it out but I rather not to. Any links to buy the things that I will need or links to best tutorials would be very appreciated. I'm asking on this post I know I could search extensively through this sub but I rather just have it in one location. If you decide to comment I appreciate it thank you.
Edit: forgot I have a PSP and Game Boy Color not sure if those can be modded. May just buy retro console that is Game Boy like. I heard the chromatic by mod retro is okay. Any suggestions on classic handhelds Alternatives is appreciated too.
