Ok, I will do this, but than I don't understand Voultar's second post to have a working reset.
Original NES systems reset both the CPU and PPU at the same time, other models like the NES Toploader/Famicom/AV Famicom only reset the CPU, this is completely normal.
Voultar was saying that if you wanted to make the whole system reset behave exactly like the original NES models then you could add a PPU reset signal, but its not necessary for the IGR to work correctly.
Once your get the IGR working correctly you could optionally add a 'third wire' to reset the PPU as well, but there is really no need to.
...Lets just try and get the basics working correctly first!
