1 chip supercic/switchless correctly(?) installed still does nothing.

Few months ago started my project of modding my SNES to a get a switchless region switch in it. Now I'm 3 snesi farther with all with boards that should work. Still all show exactly the same issues. Powers up (voltages are on the motherboard), but no picture, powerlight (unless it's the stock one) or sound.

Can anybody help?

Is it relevant that they are all SNES 1Chip V2 PAL consoles? And that they work again if it's reversed?

It is hard too see what went wrong. Which chips did you use ?
What i have seen in the past if you hook up one of the supercic legs wrong it won't give a led.
And since i am as well from the netherlands and build a couple myself. Where are you located ?
Maybe i can look at the install in person

I used a SN74HCU04N (7404), M74HCT00B1 (7400) and PIC16F630 (Supercic).
I'm in near Zwolle most of the time but study and live in Enschede.

It should be a 74HC00 not HCT. I have one in my parts bin left.
If you would like to drop by, i have some spare time friday afternoon.
Send me private message if you want to drop by.

I have a 74HC00 to and just switched them around, with no difference. I'll send you a PM.
