Universal Patcher

[zack4200]

I just played around in the Patcher a little bit with a couple P04 bins (one is the stock file I originally read from my pcm, the other is VATS deleted, some DTCs deleted, and some changes to fan temps and VSS settings, maybe a couple other things. doesn't really matter much though - just that there are changes)

Looks like the basic process to create a patch is:
1. open the Patcher
2. choose your original file
3. in the upper tab group, click the 'Create Patch' tab and select your modified BIN
4. Click 'Compare' just under the modified file button
5. on the lower tab group, click 'Patch editor', you should see a list of all of the changes you made.
- here you can either select them one by one and create individual patches for each, or select the entire table and hit 'Save' and a normal windows save dialog should appear. give it a name and save

to apply that patch, go back to the 'Modify bin' tab in the upper tab group and hit Load patch and select the patch(es) you just created, then click "Apply current patch". From there I only tested using File > Save Bin As because I didn't want to accidentally overwrite by stock bin, but you should probably also be able to hit 'Save bin' at the right side of the window.

One note, I have two different versions of UP "installed" on my laptop (I can't remember why, I should probably just delete the older one) and I noticed that when I was saving the patch, it was defaulting to the other UP directory, not the one I actually launched Patcher from. Be sure to save them in the 'Patches' subfolder inside of the UniversalPatcher folder where you launch Patcher/Tuner/etc from, or it won't find them when you try to load a patch

I don't have any e38 bins or I'd give them a shot too, but since it works properly for p04 I don't see why e38 and others wouldn't also work

Also consider checksums. I'm not sure if UP automatically ignores checksums or if it will put them in the list and expect you to deselect it. If the patch is to be applied to multiple different operating systems then UP will need to calculate the checksums, not expect and apply them blindly from a compare. As this may be one of the first times someone in the community has created a patch it'd be good to get this right now so we don't end up with bad patches floating around.

Hi guys. Thanks for the replies. Checksums are supposed to be automatically calculated when the bin is saved. At least I think so. I can create a patch, but when I apply the patch, it says successful but shows 0 bytes changed. I have tried both ways described, but fail one way or the other. Using the patcher or tuner method.
Thanks zach4200 for the detailed steps of the patcher method. I could not figure out how to save.

[antus]

Yes they are updated when saved. My point is to not include them in the patch. It is not a given that the patch generator is aware of them or considering them. It may, but it also may not. So as the author of the patch, its something for you to check. Post up the XML of the patch if you want more help. It sounds like it has no changes in it thus 0 bytes and success.

Hi antus. I just tried re-creating the P59 no vats patch, and it worked. Original P59 bin + P59 no vats bin = P59 no vats patch. Tested 2x. That's using the tuner method. I think I'm out of luck. I did write the author of Universal patcher and asked if it supported creating patches for the E38. Hopefully he replies. I don't think its supported. The patches I have made for the E38 write 0 bytes to the bin, no change. But it works with P04 and P59. Thanks to everyone for helping.

I used the Patcher UI to create a patch with the 2 bins you PM'd, and it applies 3 bytes to the stock bin.
Afterwards I opened all 3 bins in Tuner and compared, and the patched bin matches the no vats bin you sent.

Hi zach4200. Tried re-creating the vats patch and to my surprize it worked. I sent you the bins I am using. Maybe you can see something I can't. Thanks for all the help.

This is the author of Universal Patcher's reply to my email.

Hi,
Yes, it support patches for any binary file.
Because it have configuration for GM E38 files, it automatically skips checksum locations.

Well it was a bug in the program. Here is what Jouko wrote to my second email. I changed the link out of respect to Jouko. It's a beta version untested.

Hi.
Looks like a bug.
Please test this version:
https://XXXXXXXXXXXXXXXXbeta
Note: Logger have lot of modifications, waiting for testing.

Failed in tuner. 100% success with patcher. One thing I notice is under OS it's listed as 12614088, not E38. I assume the patch is only for 12614088 OS ecu's, but I don't know for sure. I will test to see if it works on other OS, when I have more time. Will keep you updated.
The patch created, disables 68 dtc's successfully. I will post the patch if a Moderator like antus or others says it's okay to.

Thanks to everyone for your comments and replies, definitely learned some stuff. This site rocks. Thanks again and have a great day.

12610488 is an E38 OS.. The patch is OS specific and will not work on any OS..
