Patch used to be small but isn't anymore?
Hello,
I'm trying to create a patch that will convert from one version of a classic game (Little Big Adventure 2) to another. Primarily the major space-hog is a CD image, LBA2.GOG (both versions over 600 MB). The GOG format is actually the same as a BIN with an accompanying CUE file for describing the layout of data on a CD.
I would expect there to be a lot of duplicate data between the two versions of the file. Granted it may be in completely different places and difficult to find. But I don't think it would be compressed.
Currently the Patch Maker algorithm seems to be finding no similarities between the files that it can use to save space. I would simply accept that the algorithm can't figure out any similarities. The only thing is, at one point in the past I somehow built a test version of my patch that miraculously came out to only 8 MB (i.e., at one point something "clicked" and Patch Maker actually found many similarities between the files).
Is there some way to coax Patch Maker into seeing the similarities between these two files again, maybe something that was present before but then got changed somehow? I don't think I accidentally left an identical file when I built the smaller patch (I tested this just to make sure and it would have been less than 4MB).
If it would be helpful I can try to send the files somehow (over a GB of data) but don't want to go through the effort unless you think it will be useful.
Thanks,
Sebastian
