Bunny Must Die .dat files.

[Spookiopath]

Hello, I post this thread in the hopes that someone might know something about this topic which has plagued me for ages now. In the attached images, I've included a comparison of the files between the PSVita and Nintendo Switch versions of the game. The PSVita version has unobfuscated files, which is great for ripping, but unfortunately seeing as it's an older handheld system, the sprites are all very low quality. The Switch version however has very high quality sprites, but unfortunately as you can see all the files are compressed into DAT files, and renaming them into a zip has no effect like with some other games. So my question to the people seeing this thread, are there any other games that do anything like this that people are familiar with? Does anyone have a clue as to how to open these DAT files?
