Buy one of those $50 hotair stations (like the Atten 858) and just heat the pins/pads until the solder melts.
Any risk of damaging the PIF using the hot air? Looking at a Swedish version of the Atten 858.
Yes there is a risk, but that is also when soldering it. Just try not to heat it for too long. I do not know if you can regulate temperature, but if you can try not to put it too high. Maybe also look up some videos. At some point I think I will buy a hot air station as well.
In my experience chips can take an awful lot and it is really hard to destroy them. But it never hurts to be careful.
I do not know if I ever mentioned this, but I am currently working on a VGA adapter for the N64. I have the thing installed in my N64, but unfortunately it is not working yet and I have no clue why (I am getting an image, but it is jumping all over the screen in a weird pattern, at least the FPGA and VGA signal seem allright
). It kind of sucks, because everything is lying at my parents and I am only there in the weekends, so I can not really work on it a lot. Once I finally get it to work I am planning to also have a look to add the clock switching. I should have enough extra I/O for it.
Interesting fact is that the version made for the prototype with long wires is working correctly (with some minor glitches from time to time), but the custom-made board is not. I think it is a timing issue considering the prototype board has a much newer FPGA.
I will most likely not add the PIF switching. I do not have an NTSC N64 and if I did I would not be too eager to mod it (unless I can get it very cheap). I have a flashcard for N64, so booting up NTSC games is not a problem for me anyways.
