This is the GBCPatch ReadMe File

Installing GBC Patches For V.1.0.1 and V.1.0.2

Operating Systems Win95, Win98, Windows ME
(these need the 1st. released patch only to make V.1.0.1)
Operating Systems Windows 2000, Windows XP
(these need the 1st. released patch and the XP-patch to make V.1.0.2)

NOTE: you may not need the 1st. Released patch if your CD installed the V.1.0.1
See "A" below on how to find what version is installed before patching anything.
Go to the Golden Bears Den, http://www.goldenbearsden.com,
and on the News Page you will find the links to patches that you may need.

A.
You may need both patches unless your CD was one that was produced after the 1st. patch was out.
If yours is one of these you will be already running version V.1.0.1
To find out follow these steps to check your version.

Start the game, and on the start screen where all the buttons are click the "Info and Credits" button.
This will display a scrolling screen with credits, on the bottom left you will see the version number.
If yours is anything but V 1.0.1 then you NEED the 1st. patch,
If it is V.1.0.1 you don’t need the 1st. Patch.
If you are running Windows Operating System 95, 98, or ME, and your Version is not V.1.0.1 you should Download and install the 1st. released patch to update your game to the V.1.0.1

B.
To run GBC under the operating System of Windows-2000 and Windows-XP you will need to get the XP-Patch from the Hypnos site, by using the link on the Golden Bears Den as mentioned above.

By clicking on the link to the XP-Patch on the News Page at Golden Bears Den you can get to the Hypnos site.
Follow the instructions there to get the XP-Patch from them.
Once you have the 1st. GBC Patch, (If needed as explained in A. above), and the XP-Patch, you are ready to Re-Install GBC on your XP System, but you have to do a little house cleaning 1st.

C.
To do this correctly, follow these steps to a better installation:

1st. thing to do is uninstall the copy of GBC that you have installed if you have it already on the XP Operating System.
Once you have uninstalled the game it is best to reboot the system to make sure you have a clean boot.
Now you are ready to start installing the game under XP with the patches you have downloaded that you need.
Start the installation as normal, and when it gets to the part that ask these 2 questions,
be sure to say "NO"

1. "Do you want to install Direct-X 6"
(this is an older version and you don't want to install an older one).

2. "Do you want to add an Icon to your Desktop"
("BE SURE TO SAY "NO" TO BOTH OF THESE QUESTIONS!")

NOTE: Before installing the game and any patches, you may want to go to the Windows Microsoft Site and D/L the latest version of Direct-X and install that, just to make sure your system is up to date. Not only for this game but also for all other games and applications that you may run.

D.
Now that you have the latest Direct-X installed and also a clean install of the game, you are ready to apply any patches you may need. (Refer to "A" above)

IF you need the 1st. patch then go to the folder where you have it stored and double click it.
This will start the installation of this patch, just follow the prompts and let it do its thing.
Now your Game should say it is V.1.0.1 if it did not before.
If you had to install this patch follow steps in "A" above to check it out.

E.
Now you are ready to install the final XP-Patch in your game to update files to work under Windows-2000 or Windows-XP Operating System.

To do this, and once you have your XP-patch file, and the information they sent you in an E-mail with your password and information needed for the patch.
Go to the folder you have downloaded the XP-Patch and start the installation by double clicking on it.
Follow the instructions on screen and enter your password and info as it asks for it.
Once it is done you should be able to now play the game with no problems.

BE SURE TO PUT ALL YOUR PATCHES AND ANY INFORMATION WITH PASSWORDS IN A SAFE PLACE SO IF YOU NEED THEM LATER ON TO REINSTALL YOU WILL HAVE THEM.

Additional Information that may help:

This is a quote from another thread on this posted by Kurtman9, on the Forums at GBD that may help you out:

I finally got this solved with some help from Hypnos.
For those who may encounter this problem, here is what worked for me:

1) Uninstall Jack (completely)
2) Reinstall the Standard version. From the CD, copy only those files in Setup/JNGBC/Data that are not in the Jack 6 Data Folder on the hard drive (I found when I overwrote the files, the game didn’t work right)
3) This should give you a full install
4) Then, if you have version 1.0, apply the 1.0.1 gbcpatch, (located at Activisions web page)
5) Then, install the XP JN6 upgrade
