Pet a raison NET dimm =/= dimm board

il te faut une prise réseau et tu peux multiplier le prix par 2

Edit : voire 3 https://www.leboncoin.fr/consoles_jeux_video/1022484129.htm?ca=2_s

il faudrait un original Virtua fighter recent qui contient le GD rom de maj et le security chip kivabien

Le kit de mise à jour était bien avec virtua fighter 4 FT (le gdrom vf4 ft + le gdrom de mise à jour). Le dongle est le même que VF4 ft.

On le trouve maintenant tout seul, mais à des prix bien abusé (+100 euros).

4.01 firmware will play everything and support CF as a storage device
3.17 firmware will play everything
3.03 introduction of net booting/net boot keychips
2.xx introduction of basic ALL.net functionality
1.xx standard dim board - no network

4.01 is the best bet for all uses, 4.02 is a hacked firmware to remove the CF mfg name check, that's the only difference from 4.02, it must be net booted, as obviously it's not a pressed hack.

There is also 3.17 CDR firmware which has been around for donkey's year, which allows CD-Rs to be used - the only issue with this is it bombs out after a couple of hours.

bon y'a un type qui y est arrivé  :-/

Which brings me to the question if there's a way to downgrade from 4.02 to 4.01 (or even further down), or is it a one way street?

Yes, downgrade is possible by netbooting a hex edited firmware update so it thinks it's installing "4.03". The actual firmware binary is unmodified, it's just the installer part that is modified.

andygeezer wrote:
Not possible, there is no code in firmware less than 3.03 for net booting, so I can't explain how that worked!!

And yes you can downgrade, by holding down the test or service button (can't remember which) on the Naomi mainboard while booting the firmware disc  (puts the Naomi into force mode).

Damn  Wish I had kept one of them as it was then for trying to find out how come it was working. Here's the only pic I have of netbooting pre 3.03 (upgrading from 2.17 to 4.02)...

EDIT: Or am I looking at the wrong numbers?
