Unrelated OVL format #302

Closed dtb01-77 closed 1 year ago

dtb01-77 commented 1 year ago

Hello, I am trying to open and modify a .OVL file for a car radio head unit. Yes, I know this is pretty far from what Cobra-Tools is for, but I have not found anything else useful in opening these types of files, but if anyone has any suggestions please let me know. All I am trying to do is edit a few images in the .OVL, and I know that the images are there because I can see named .png files when I open the OVL using note pad. Anyways, when I try to open the .OVL file in Cobra tools I get the following an unpack requires a buffer of one bytes error. Please let me know if you have any ideas on how to fix this. The contents of the olv_tool_gui text file with the debug and error in it is linked below

Thank you!

What game is this? You should provide a sample file, since it doesn't seem to be one of the supported games.

it is not a game. It is in fact an OVL for the program for a touchscreen car radio. I will attach the file below

Totally unrelated file format, as expected. You'll need to reverse engineer the structure of 'your' OVL format to be able to modify it.
