Hi,
Sorry to post for help with my first post, I was hoping to do better. It seems I messed up something with my NESRGB install (2.0) on my Top Loader.
Did I fry something?

The image is all garbled, especially backgrounds. Everything looks black & red in Super Mario Bros. 3. Sprites look kinda OK.
My soldering might not be Voultar level but is looking pretty OK. I don't see bridges anywhere.
And the worse thing is that when powering it on a few times to take the picture above, the issue seemed to be getting worse and worse... and now my NES barely works.
I through I had been very careful with it

EDIT: I tested for continuity an found out that one of the square pin strip of the adapter board has a bunch of bad connections on one side. I'll desolder and resolder the whole thing to see if it fixes the issue.
EDIT 2: After reading through pages of this thread, it seems the lack of continuity on pins 2-9 and 14-17 is normal. All other pins have continuity to the NES board. I probably fried the PPU or something else without realizing it. After powering it on/off a few times it degraded to the point where now I only get a black screen. I'm really not qualified to troubleshoot it more that. I'll probably try swapping the PPU by a clone just to see if that's the source of the issue. If not, that'll be the end of it.
