New update I have added a 74HC373 to my ver 7 NES and it works great with the powerpak.
everything seems to work great. Most of my problems seem to have been from bad connections.
at this point I would say this is a universal fix for any front loading NES with a RGB mod to enable powerpak compatibility

I tried a duo ppu mod Rgb/composite+RF.
For the most part I piggy backed both PPUs then I select the ppu I want by supplying it with 5V from a switch.
I was also going to use a rgb led for the power led. If I am in rgb mode it will light up blue and red for composite video mode.
I Had everything working but it added more vertical lines/noise.
I went back just used the RGB PPU to minimize the vertical lines.

A funny /dangerous /stupid thing I did was piggy back both with PPUs to see what would happen.
I got no video but the sound would still play but it was playing very fast.

After playing around I noticed older v4 NES systems have more vertical line noise in the image than the ver 7 NES.
this is something to consider when RGB modding a NES.
Games run from the powerpak display vertical lines more intensely.

Been checking the retrozone website for a while and noticed today that the power pak is available to buy if anyone is interested.
