What could make a pirate cart only work on clone?

[infiniteneslives]

I can see /OE grounded, it doesn't allow for making use of CHR /RD signal but it's not of much concern.

So close, but so far away...

The famiclone had no address/data multiplexing, so no bus conflict. Oops.

Has anyone ever figured this out? I bought 2 copies, one for my brother and the other for myself, but I am at an impasse with how to get them running on genuine Nintendo systems. If anyone is interested, I can send the boards to you to hack on.

The answer is only a few posts back...

With a help from our friend from polish forum dic-sc7, we found a solution to make this cart working on real hardware (Famicom/NES). All you need to do is simply desolder OE pin from CHR-RAM and solder it to unused CHR/RD pin 17:

I did that, and it did nothing to get this running. That only apparently works on the 150 in 1.

I tried it with the specific cart discussed in this thread and it work perfectly. You have to lift the /OE pin from the pad and then wire it to /CHR-RD on the cart connector. If you just wire it without lifting the pin it doesn't work.

SkinnyV if you don't mind me asking, where can you get this particular multicart?

[SkinnyV]

I got 2 from a user on another forum.

SkinnyV: I have given up on my carts. If you're willing, I could pay you to get mine functioning. I would hate to feel like I wasted money on buying them, and with as many games as are on them, I am cool spending a bit more to get them working.

Remember that you can save on shipping by opening the cartridge and sending only the PCB, not the shell.

If it's only for your personal copy, I will do it for free if you are unable to do it yourself.

I have some cartridge like this(PPU /RD not connect to the VROM or CRAM)!

I found on my dumper device,it can read the vrom data,and write the cram,but on real famicom,can not read the vrom(read/write cram) data correct.

When I dumped the rom use tapedump and chip-on-board famicom,then the rom can work on emu correct.

I'm currently trying to figure out how to make work a cartridge who works on noac on my famiclone. Lifted pin 24 (OE) from CHR-RAM (chip km681000blg, who is a cmos sram) and pin 24 from a hy6264alj-10 chip ( also a sram) and use a wire soldered to pin 17 of the cartridge, but no results, glitched menu, and glitched games.

Sorry for reviving an old post, but, I don't know what else can I do for this problem.

Unless you are talking about the same cart that was discussed in this thread, it might be easier if you would show hi-def scan of both side of the PCB and also describe a bit what is happening.
