You can tie pin 2,3, and 4 on the pic chip together as it all pulls high.
The collector of the pnp transistor connects to the rgh nand.
You can eliminate that pfet as most chips now uses the same chip as the tx coolrunner, even the clones. they all have the same cr-en point. This should cut cost down some.
You can also ground out pin 12 of the pic chip as the debug can be modded on all glitch chips anyway.
The 2 led pins needs to have some pads for the resistor.
When i do try this out, i will be using the squirt secondary nand pcb as it has all the pinouts already.
Will update/edit as i am waiting on some answer from the author.
Here is a picture schematic of my revised. Paint for the win!!!
