Why would you flash 4.01 when you can flash 4.03 to get (non Hagiwara branded) CF and CD-R capabilities?

I had misread. I will need to look at the daughterboard and get back to you, have you checked the capacitors on that board with an ESR meter?

That's actually a clever idea for a patch. I was about to give up as I read Metallic 's explanation xD

That makes more sense, though the likelihood of anyone switching from GD to CF or vice versa without disconnecting the battery on the same setup is rather low.

It would be useful to people using regular DIMM or using NetDIMM to boot CF/GD/CD-R, this would decrease load times as it would no longer perform the (arguably unnecessary) CRC checks. If you aren't using a NetDimm, you can't really send a packet to disable the CRC check since it isn't connected...

Your NAOMI DIMM board buffer chip is toast. You will need to replace it. It is labelled as IC12S.

Getting the CRC would actually be useful to add a skip in the triforcetools that would not send the game again to the dimm if the crc matches the binary you want to send. Transfergame does this already. I am also considering skipping the memory checks altogether as a patch in the dimm firmware...

I would be interested in it as a curiosity more than anything else. Truth is however, it would not be economically viable considering netdimm can be had for €250 or less and you aren't likely going to be able to build something equivalent and sell it for cheaper.

It's very common, yes.

It seems like a dead buffer chip, you probably need to replace the fairchild DIMM board buffer chip (IC12S) to fix this. This requires fine pitch soldering

It does work, you need to connect it to an existing GDROM PCB, making this somewhat redundant, you also need to replace the menu (you can use a MENU folder on the SDCARD for this purpose if memory serves me right) with your targeted game, this means only one game at a time (or per SD card) will...

You would need to test with another PSU or another dimm board. Cartridges don't draw nearly as much power, especially on the 3.3v line so that's not a good test.

You can netboot from 2.xx (despite the error 31 at boot) and you can update straight to 4.03, I have done it on 2 netdimm thus far with no issues (using the offiical transfergame).

Something is very wrong, 4.72 on load when you started with 5.32 is way too much of a delta and should not happen, I suspect your PSU is low grade at least and has massive ripples, change it. 4.72 on load is way too low, I am surprised this system even boots, you need 5.00v minimum for naomi2...

Even off load your voltages on the JVS interface are way too high, you are literally killing your naomi board.
