NES NASA and Creation NES clone mods

[SaturnHST]

I have these NASA and Creation NES clones that are PAL 50Hz and I want to mod them to NTSC 60Hz. From what I've read, it's possible to convert a PAL NES to NTSC by swapping out the CPU, PPU and crystal oscillator for the NTSC equivalent from a US NES or Famicom. Does that apply to these NES clones? They do have cloned CPU and PPU (TA-02NP, TA-03NP1, UA6538, UA6527P).

I managed to desolder the CPU, PPU and crystal from a US NES and install them on one of the clones. The clone chips were already socketed so that made it easier. Now it is NTSC 60Hz and works on all US tv's.

I have another NASA clone, but this one uses a NOAC unlike the others. Any ideas on how to change this to NTSC 60Hz? On the board there are jumpers marked "P/N". I am assuming I need to change the crystal for a NTSC one and join all 3 jumpers?

Also I noticed that behind the NES cartridge connector, there were unpopulated holes for an additional Famicom cartridge connector.

I have seen some other variants of this that has a top loading Famicom slot as well: http://www.nesworld.com/pirate-ns90a.php

I took a chance and ordered a Famicom cartridge connector, soldered it in, and to my surprise it works. So now this has 3 cartridge slots: front loading NES slot, top loading Famicom slot, and internal Famicom "built-in" games slot. Next I will try to cut a hole in the top casing for the new slot.

I'm Pretty sure that "creations" here in chile are all 60Hz.

NASA ? wtf ='D

I have NASA, SINASA, Creation, ARGO, YESS! and they are all PAL 50Hz.

Very interesting. A console with both, NES and FC slot. First time seeing such thing. Famiclones never disappoint.

The MrJamu has done the same to his clones, you might want to send him a message, he's very helpful and knowledgeable.

Yeah I've seen that, but he changed it from PAL 50Hz to PAL 60Hz. I'm changing mine to NTSC 60Hz. Also, that mod only works for the "TA" series clone chips and will not work on the "UM" series chips.

So far I've converted three of the discrete chip clones by swapping in the NTSC version chips. I'm not sure how to change the NOAC clone.

I believe he also owns that clone too, and in addition being very knowledgeable he is also very helpful. You should drop him a message and see if you could work things out.
