I continue experimens with possibilities to build soldering-less RGB adapter for famicom/nes. Device works via cart port as pass-through adapter. It based on ppu bus sniffing. No frame buffers or something, it draws directly to the screen on the fly.

Actually i didn't replicated ppu, i used trick similar to one used in mmc5 for tracking current beam position, using this information i can decode ppu fetches and throw pixels to the screen. Only sprites evaluation process vas partially replicated

Call me an idiot. I really don’t understand this, but the idea is amazing. So you’re building a 2nd NES motherboard inside an adapter? Cuz i’d think you need CPU, graphics chips, etc. ....to do this. I think i am misunderstanding this complete post.

Каким размером будет готовый адаптер? Насколько маленьким он может быть? Нужно ли ему дополнительное питание?

Размер не больше чем нужно чтобы вывести ргб разъем за пределы корпуса приставки. Доп питание не нужно

So no issues with light guns etc? No latency should mean they work fine which is great!

Wow, that looks great. I hope you pull it off—the current one involving desoldering a DIP-40 is too hard to install.
What would happen if a game changed things mid-scanline? For example, dialogue windows in the Japanese version of Mother.

Any tricks like this isn’t problem. Adapter display exactly what was fetched by the system ppu

Maybe you should focus more on fixing the numerous bugs and glitches on your old products instead of releasing new bug-filled products.

Very cool, you always impress.
I am waiting for a certain soldering pro to say something negative about this lol.
