With all the holiday activity, I never posted an update. I seem to have gone backwards on this project. I purchased a pair of Type-3 Chihiro for practice. I have every reason to believe that they went into the shipping box working, and the bubble-wrap was done very well, but the both had...

Package received and in good order. Thank you.

Seems I have signed my self up for an ADVENTURE. I will let everyone know how it goes. Thank you everyone for your help so far.

Msg sent.

Dang. I knew I forgot something. Got pictures of the BIOS screens, ping results, even the force feedback belt (I'm trying to find where to buy them). No pictures of the Chihiro. I really should have taken a photo of the top board and its jumpers. In looking through this forum, it looks like...

I am attempting to help a friend/local arcade operator get their Outrun 2 cab back to being reliable. Current status: the system often fails to boot, complaining that the GDROM lid is open. It will sometimes be running fine and stop, complaining that the GDROM lid has been opened. They have...

It is really hard to find DIMM firmware online and 4.02 is the only "known good" firmware I have. 3.17 would be fine, but I don't know if that failed because I am doing something wrong, or because the file is bad. 3.03 doesn't seem to ....*blink*.... wait, now the whole netboot thing is...

Anything unusual about pushing a firmware update to a Triforce Type-1? I tried the same "TransferGame.exe" and "FW_Netdimm_402.bin" that upgraded a 256mb NETDIMM on a Naomi just fine. On the Triforce, it seems to accept the transfer, the screen goes black for awhile, then it reboots, still...

No firmware changes needed. You're not too far off on JVS. It is RS485 over the D+/D- lines. Same ground. The +5 volt line is instead a "sense" line used on startup for each device on the JVS chain to be identified by the master. While the ground and data are bridged across the JVS input...

Oh good. I used the same pinout. Thank you for letting me verify.

(replying to a question on ebay) I'm not sure what device is the "UD USB". Is that the "Undamned USB Decoder"? (Had to go research that) So, um, it would work...Let me tell you why this project exists. I was intending to build a single one-off of this JVS adapter, with hand soldered custom...

I don't think any rewiring is needed, you should just plug the USB2DB15 (or rather, all 4) into the DB15-to-JVS and it would all work.

Let me try explaining. Every GD-ROM title is encrypted using a unique encryption key (think very long password) the key chip stores the decryption key (password). You can't mix and match keys and titles. The deal with the zero key is for preservation using copied titles. GD-ROMs at this...

Had a slightly odd NETDIMM upgrade, so I thought I'd post. NETDIMM (sourced from Hong Kong) reported itself as version 3.13 in the BIOS test. It would not accept "FW_Dimm317.bin" (maybe I wasn't supposed to use that one), but accepted the file "FW_Netdimm_402.bin" directly. Oddly, the upgrade...

Got it. I was trying to upload the wrong NETDIMM update ROM. The steps above absolutely create a valid zero key using the PicKit 4. Thanks everyone.
