I was hoping for a better post, successfully reading/writing the chip but sadly that is not the case. Not good when we want to get an image of it. They enabled the read-protection bit, so you can't read back the chip, and the only way to clear that is to erase the device. Unfortunately, bad news, and I had a feeling this would happen. From what I heard, Hydro uses 546-0024-03, so my plan was once I got Hydro Thunder, copy the BIOS from that chip and plop it on this one, and see if that works, instead of physical transfers.īought the programmer, downloaded it's software, got the pinout of their custom JTAG header, and fired it up! So I went on ebay and managed to find one, with the sticker of 546-0014-02. And in pictures, I saw they provided the header on the card! Easy as pie! So being a tech guy, for shits and giggles, I looked up that part. It seems that even getting that specific card in general is hard, let alone with the correct BIOS chip (the one with the sticker). It is in working condition, and I saw that one of the rarest things to get for these things when they go out is the Video Card (The 3DFX Quantum 3D Obsidian2 90-2440). I have Hydro Thunder on the way, waiting on the freight delivery. Click here for the latest update: Ī little bit of background. We are getting the Diego board to unlock itself using a 0014-02 card, with ONLY editing of the Hydro.exe file on the hardrive. : MAJOR UPDATE: This is partially working. : MORE MAJOR UPDATE: This seems to be working 100%. I'm not responsible if you trash your EXE, or anything else for that matter.

If you can use a Hex editor (kind of like a text editor), and know how to open the HYDRO.EXE on your Hydro Thunder computer's hard drive, then you can probably follow this.
#Hydro thunder video game Patch#
HOW TO AND INSTRUCTIONS: Not sure where/if I can post the patched CHD image here, or even just the patched HYDRO.EXE, so for now I posted the instructions and hex code on how to patch your own HYDRO.EXE.
SCRIPTS I WROTE AND USED TO HELP ME BYPASS THE CPLD: HOW IT WORKS/WHAT THE CPLD/SECURITY CHIP WAS DOING AND WHAT THE PATCH DOES: I did not post a CHD or a modified EXE because I am unsure of the legalities of it, so the instructions on how to patch your own EXE are provided. : Refer to the links right below for information, as well as how to get this to work on your system. I'm trying to keep this as the in-depth development/testing thread and the other one more "user friendly" to everyone.
