Did the Ultra Pif mod exactly as instructed but doesn’t work. I get no video but hear audio except it’s in slow motion. This Ultra Pif was taken out of my fried Pal Console which i failed to install a ReN64 psu mod and the i put the Ultra Pif into my replacement NTSC motherboard. I then started having this problem once it was transferred. I tried converting the NTSC console into a Pal one by replacing the U7, U15 and the X2 Oscillator, and i get the same problem. Is my Ultra Pif at fault or did i miss something? I don’t know what the JP 4,3,2,1 bridge points are, don’t know what the BL point is on the Ultra Pif board and i get a flashing LD2 Red Status LED with the Green LD3.
By the way my motherboard is NUS-CPU-05 and my faulty Pal motherboard is NUS-CPU (P)01 revision. Hopefully i can fix that motherboard someday.

Here are some pics.

I have a PAL N64 (NUS-CPU (P)-01) which has a MX8330 for U15 but a MX9911 for U7. I tried the Direct VLCK method (DENC-NUS) and lifted pin 1 on U7 (MX911) and connected the pad to Xtal (pin 16 on DENC-NUS is connected to FSEL). However this doesn't give any Video/Audio. Neither Composite/S-Video/RGB or HDMI (have an additional N64Digital installed). Putting pin 1 on U7 back restores all video signals. PAL and NTSC games boot and seem to run under 50 or 60Hz (according to N64Digital). Composite is in color (via RT5x). Lifting Pin 1 on U7 and bridging the jumper on the N64Digital also works. However here composite is then in black and white. I didn't try and connected stall to the pin 1 pad and have the jumper on the N64digital closed at the same time as that probably will also cause a crash? Any thoughts on this?

I have a PAL N64 with Tim Worthington's N64RGB and I have installed the Ultra PIF chip on it. Now when it switches to NTSC mode, the screen becomes unstable and flickering. I have noticed the flickering is specifically visible on black screens. Also my N64 becomes relatively hot.

My N64 has a MX8350 PLL chip and MAV-NUS video chip. In have installed it with the direct VCLK method and with composite video. First I removed the PIF chip and soldered on the adapter board. Next I connected JP1 of the UltraPIF PCB and then I lifted pin 3 (VLCK) of the PLL chip and connected the pad to XTAL, lifted pin 23 (mode select) of the MAV-NUS chip and connected the lifted pin to FSEL. Finally installed the UltraPIF PCB on the adapter board. Do you have an idea what is wrong?

Hi! I own a Jap RGB capable N64, whitch i have a bortis RGB amp installed. Before the Ultra Pif was installed, everything was working ok.
Now with the Ultra Pif i have the following issues:

Menu boots fine with PAL settings and all is ok, PAL games works like charm.
When select NTSC for the menu or NTSC game, i cant get sync.

Thanks.

Hi Jago85.

This is not an issue but a Quick Question. Does a Pal console with UltraPIF play NTSC games at exactly the correct speed? Or are there any slight discrepancies vs an actual NTSC console?

thanks for replying if you can.

How can you reset the ULTRAPIF settings? Upon boot I toggled the 'direct boot to cart' option in the settings, but I do not know how to undo this option or get back to the settings menu afterwards to make any further changes.

Grateful for assistance as I am unable to find any user information online.

Hi,

Looking at getting a batch of these made for our store. However, the STM32F070CBT6 and SI5351A-B-GTR are basically not available for a year+ due to shortages.

Is there any sort of alternative or redesign planned? I assume you are seeing this issue too (or maybe not, as not making many??)

I am looking to install the UltraPIF into a PAL N64 to make it multi-region. The system will see use with an Everdrive X7.

I'm hoping just to clarify the behaviour of the UltraPIF in certain scenarios when used with the Everdrive X7 or similar flash cart. It's a bit complicated because the Everdrive does region detection at boot, but it can also launch any region of game after it has started up. I'm especially wondering what the behaviour will be if I launch a PAL game from an Everdrive X7 (UltraCIC-III) on a UltraPIF modded system.

Here are my current assumptions, I'm hoping if you could offer some guidance on whether they are correct or not:

1: UltraCIC-III will always choose NTSC on UltraPIF

My rudimentary understanding of the UltraCIC-III is that it achieves automatic region detection by first attempting to boot into NTSC mode, and if that fails, it switches over to PAL mode and reboots.

I think this is the UltraCIC-III code that is running in the Everdrive, and it has NTSC mode set as the initial region:

https://github.com/ManCloud/UltraCIC-III/blob/16fd1eecd8528ab2d7fd0490f24fb7738017bd39/UltraCIC-III.asm#L1038

So it looks like it'll always boot into NTSC mode when used with UltraPIF?

2: UltraPIF uses the CIC check to set frequencies

This one I'm not really sure about from looking at the project, but does the UltraPIF use the CIC check to set the NTSC/PAL mode (FSEL and clock, etc)? Or does it choose the mode based on the actual game behavior?

3: Booting PAL games

The Everdrive X7 is capable of booting PAL games on an NTSC console, and vice versa, through some magic that the Everdrive firmware does. On an un-modded N64 this leads to some weird video output because the frequencies are slightly off and the video encoder chip is still set to the console's region. I believe this causes PAL on NTSC to output as NTSC50, and NTSC on PAL to output as PAL60, and TVs don't always deal with this very well.

My assumption is that the UltraPIF won't/can't know that the Everdrive is actually booting a PAL game from NTSC mode, and will therefore always stay in NTSC mode. This will lead to PAL games booted from the Everdrive to behave as if they're running on an un-modded NTSC system, with the weird video output. Am I correct on this, or does the UltraPIF derive the region via some other method?

Thank you for any assistance you can offer.

Hi I have a problem. I’ve installed an UltraPIF acquired recently from ModinFrance with N64Digital on a Pal board. I’ve wired up the N64Digital to control the video clock speed and it works as expected. The N64Digital output is beautiful and I adore it. Problem is the analogue audio always drops out after 12-15 mins of play affecting RGB / composite. The composite output for NTSC games is also black and white which isn’t a problem for me but wondering if that indicates an underlying problem. Any help will be greatly appreciated.

I have a NTSC-J N64 with both an UltraPIF and a N64 digital installed. Everything works perfectly with sole exception of Perfect Dark which will not recognise an expansion pak. All other games tested detect it no problem. It also worked previously with just the N64 digital installed. Any thoughts on if this is an installation issue or a known problem. Thank you in advance for the help and for the UltraPIF in general, it’s fantastic!
