NES TOP LOADER: New NESDEV AV mod!

[leonk]

I'm not sure how many people follow the NESDEV forum, but a lot of progress has been done there in regards to the regular top loader video quality.

The gist of it is:

- I purchased an extra top loader
- I took it apart and started working on trying to figure out how to get clean AV out of it
- With the help of others at NESDEV, I've managed to produce perfect Front Loader video picture quality (using RCA cables) out of a top loader.

Total cost: less than 5$ in parts.

PRO: the ultimate 8-bit nintendo game system is a real NES Top loader with the newly designed NESDEV video amp that uses the exact same video amp IC as a front loader.

CON: RF modulator doesn't work anymore.

Post the circuit to fix it.

Post the circuit to fix it.

seconded. get us some schematics.
Not being able to use the rf anymore isn't a con really, imo.
I mean, the whole point of this video mod is to not use it anymore, right??? I ripped the rf right outta my toploader anyway.

the schematics are posted in the above link.

Wow, they linked to my schematics in one post. The multicolored ones. Interesting...

i haven't been on this forum in a little over 2 months.


has there since been a fix for the 'lines' on the US redesigned 'Top Loader' NES?

if this is true, i will not go ahead and purchase the AV Famicom...

[Kamino]

clearly, i am too retarded to sort this mess out.
If someone could write a howto on this, such as those that exist for so many mods(the info found at gamesx.com , and john soper's page www94.pair.com/jsoper are prime examples) I'd be most appreciative..

Still looking for an answer to my question. Leonk?


I am not sure if omnedom is frequenting this forum regularly still but if this is a fix for the lines, and someone can do this fix as well as the AV mod for me, that would be great.

[omnedon]

I will be trying this mod soon. I have no reason to not believe that it will be as successful as leonk has found. I still have to sort out input costs and labour.

And no, I'm not able to post as frequently as before.

Click here for the schematic. leonk, can you take real world pictures of the changes you made, or even better, a step-by-step modding guide that includes pictures of the PCB at each step?

[Kamino]

Christmas is busy time for me, so not yet.
