Ok, so I did the work a week or two ago. I had some issues but it’s all together now and works fine. Here are my observations.
The “optional” wiring can be tricky. Wiring it to a %100 Grade A made in Japan PCB is no problem at all, the new screen driver PCB has solder pads not so durable…I’ll leave it at that.
The pre-wired touch sensors are bullshit. You will accidentally hit them constantly forcing you to cycle through every stupid Radio Shack ghetto blaster color pallet to get back to the only usable one. I hate this feature soooooo much.
“Retro pixel” mode is pretty much required and of course its default OFF. So you “need” the OSD wires soldered in to turn it on…right? I don’t know. I have in fact somehow switched it on and off with just the touch sensors. Too many fucking inputs for a damned screen!
Battery life isn’t too bad as long as you use the best batteries on the planet, either Neo Champ or Enerlop. If you try to use a flash card, this screen, and cheap AAs it probably won’t even power up. The vast VAST majority of all current is going to the new screen. I honestly wouldn’t be surprised if batterie wires or something ended up getting brown from easily several times the current going through them nonstop. Noob collectors who buy shit all day and never play it will never complain about this.
Super bright sunlight, which is where the NGPC/NNGPC looked FLAWLESS is now a joke, the sun totally overwhelms it.
When I switch the system off to change carts the screen doesn’t want to power up with the rest of the system. I have to wait like 30 seconds. Tards flipping channels on their flash carts won’t care, I use only real carts so it pisses me off a lot.
The combination of the stupid touch buttons, stupid modes, and insane current draw basically turn your perfect piece of 90s Japan into janky Chinesium eBay bullshit. The if you buy the replica shell to go with it your NGP experience has you literally not touching or seeing or even in some cases hearing ANYTHING made by SNK, only the ROM on your flash cart is theirs and the hidden away PCB. To me this just isn’t right.
HOWEVER, attached is a picture of my playing Densha de Go! in front of a fire…and I’ve wanted to do that for literally decades. For this there is no substitute, you need the no-name Chinese bullshit, and therefore I am grateful for the bullshit. I will be keeping my old screen though for when this one dies for no reason in a year or three.
I do NOT recommend doing this to your only NGP.
