So I have a new, functioning digitizer/LCD in my lite. I bought the switch as a “damaged unit”, and it had a cracked screen and casing. I think it was thrown or sat on. Anyhoo.. I’ve had to replace an İÇ, a few caps, and an inductor coil (red circle in pic) and it’s finally up and running. But the touch screen doesn’t respond to anything. I threw in a functioning motherboard and it worked as it’s supposed to. I’d love some pointers as to how I’d go about troubleshooting.. thanks!

Bottom left corner of the board is where jkyoho spotted whatever that is. Definitely doesn't look normal, whatever is there. Could just be the pic though

Oh.. thanks for clarifying @Illuminaticy. I thought that area had to do with audio processing. Here are better pic. The original pic was just to show what components were replaced.

    Rp5 is shipping with 8gb of ram now

    haha hello
  • Psionic Roshambo @ Psionic Roshambo:
    @K3Nv2, I think the RP5 has had 8GBs for a while? I know mine has 8GBs not sure it's needed for emulation though? Probably 4GBs is enough for 99% of what it's fast enough to emulate? I could be wrong if it can do like GC and PS2 stuff maybe more is needed? Probably stream the ROMs like the consoles did off the drives.
  • Psionic Roshambo @ Psionic Roshambo:
    I believe what they do is OS and translation layer (emulator) and the emulator has its RAM like 36MBs for PS2 so like 3 times that maybe as things are shuffled around, a frame buffer and. Load the data from the ROM file into that systems RAM. I think I read that even 2GBs is enough if your just using a Pi for emulation.
  • BakerMan @ BakerMan:
    What's an RP5?
  • Psionic Roshambo @ Psionic Roshambo:
    Raspberry Pi 5
  • Psionic Roshambo @ Psionic Roshambo:
    For me it's just an emulation machine
  • Psionic Roshambo @ Psionic Roshambo:
    Like a super mini system, I use Batocera as an OS and it's pretty easy to set up, has a ton of UI skins you can make it look almost anyway you want. Still would kill for a WiiFlow like skin (some are close)
  • Psionic Roshambo @ Psionic Roshambo:
    I bought the 8GB model because my thoughts on that is the the difference between the models is like 20 bucks so why not get the good one just in case.
  • Psionic Roshambo @ Psionic Roshambo:
    Almost never hear anyone complaining about too much RAM but not enough? Yeah best to avoid that one. Lol
  • Psionic Roshambo @ Psionic Roshambo:
    I did kind of overshoot on storage, a 2TB nvme drive and I think 1TB would have been plenty.
  • Psionic Roshambo @ Psionic Roshambo:
    Probably have like 700GBs of stuff on it now, and don't think I can add much more.
