Naomi Pi 'WiPi Netbooter' - compatible with Pi 34

[Suteneko]

Hey thanks for the reply @Chunksin. I sent her a message regarding it on Arcade Projects myself though maybe better for you to ask as I am rather dumb when it comes to anything code wise.

I've been considering buying a second Naomi just so I can play other games without losing my score board but that in itself has risks as it seems that periods over around 2-3 weeks of no power kills the score board as well.

Had that happen early on, when I took a little break from the game.

So really would love to find a solution for this.

I'm probably the only one that would like this functionality anyway and really just for only one specific game. Though would be awesome to be able to do so as well on the Naomi shmup library as well.

Again thanks for your hard work on Wipi it is much appreciated!

Used BalenaEtch to write this, and on the verify it said image not burned correctly. Tried it on two different cards. Is that likely to matter? Tried one on the Cab, and I could see the wipi and connect to it, but it didn't find the netdimm (I followed the instructions on the PDF).

Do I need the Pi connected to a monitor to do the setup properly?

 

[chunksin]

No, it all works from the web interface. If you can see the WiFi network chances are it burned ok, did you remember to select SET after the IP and subnet, then reboot the Naomi? Which IP did you use for your netdimm?

 

[deanzor]

10.0.0.3

I'll try again tomorrow. Cheers Rich, amazing work as always

 

[deanzor]

The issue here was my dimm0 had died. I swapped over with dimm1 and we're back in the game! (As an aside - can I buy any functioning pair of dimms to fix that?)

Great to have the menu on boot. Some Qs from me:
- Which region should my Naomi be set to for best compatibility with the romset?
- If I'm doing is netbooting, is there any reason to upgrade my fw beyond 3.03? Any benefit?

Thanks

 

[chunksin]

Sorry Dean - slipped my mind to answer your PM about this, you're best setting to JP region for compatibility with the most games, netbooting wise you won't see any benefit from updating from 3.03 to v4 unless you ever want to use CF cards or run games from CD-ROM. Dimms seem to be slowly failing, I think a lot get killed by overvoltage, they are really sensitive on the 5v feed. If you can find a cheap non netdimm on firmware 2.06 it will work with a netdimm and you can safely update it direct to v4.

I've been told it's possible as the naomi homebrew doesn't use the SRAM storage and could potentially read the data and send it back to the Pi to be stored for later. From DMs notes:

'Game SRAM is available at 0x200000 and is 0x8000 in size. This appears to be used by games for high-score tables, as game settings and unlocks are stored in the EEPROM.'

So it looks possible but I don't think DM is interested in getting it working herself. Might be a future project for me after the card printing is finished.

update

Don't forget the new update function, download update 6.1-5 soon to get a bonus feature!

How do we update? Can’t see it covered in the documentation or any options in the 6.1-4 I’m using?chris29222022-03-02 08:03:54

 

[chunksin]

Look in Setup-Manage WiPi-Update WiPi, it should be there

Edit: see page 12 of the manual

Fantastic work! I upgraded my setup this afternoon and the load times seem much faster

Can someone confirm if the menu works in 15khz mode, please? I can't get my screen to sync (it's fine in-game though)

Many thanks for all your great work on this

 

[chunksin]

I've had it working in 15Khz on an LCD screen but not a CRT, it should be controlled by the Naomi rather than the software so strange it won't sync, could you try the Naomi diagnostics menu and see if that works? it's in 'Manage Netdimms' under the Setup menu

 

[channel27]

Hi,
Will do, thanks.

I thought it was the Naomi that did the stripping but I'm reading that some games don't run @ 15Khz: -

I'll give the diagnostics menu a go when I get home

Thanks Rich for your epic work on this, looking forward to setting this up on my pi with screen this summer!

 

[steling1]

Hey Rich,

Ive been using this for some time now and its really ace, a big improvement on using the Piforce tools...

I notice you mention a newer version 6.1-8 is available, is there anywhere I can download this as the link is for 6.1.4...

 

[chunksin]

You can go to the Setup menu and Manage WiPi - you can update from there to the latest release

 

[Suteneko]

Man super stoked for SRAM backup update!

Shame I let my Cleopatra Fortune score board get wiped already by finally loading another game but I at least took a screenshot of it first.

 

[Rob_bob_2k6]

Thanks for your work on this chunksin, very slick interface.

I’ve been using this on my Naomi driver, I’m using it to send the on screen menu. I wanted to be able to set the game assignments but it seems like it may require a joystick. Has anyone found a solution to do this in a driver cab?Rob_bob_2k62022-06-13 17:11:32

 

[chunksin]

That one is a bit chicken and egg because you need to set the analog controls to on in the OSM - one thing you can do is SSH into the Pi and go to /sbin/piforce/dm_netboot/.netdimm_menu_settings.yaml and set the option enable_analog to true

That should get your controls working but you might need to go into the menu and calibrate them if they don't work as expected. Also make sure your Naomi is set to 1 Player in the service menu otherwise it will try to read player 2 inputs and the menu will constantly scroll.
