February 20Feb 20 The game contains .dat files that appear to be compressed similar to those of Mario Tennis Aces, another Mario sports game on the same system by the same developer. However, the actual compression used seems to be different from that of Aces, which apparently uses what seems to be rather unique type-0x50 compression, and there exists a tool to decompress those files which I have tested on these ones, and it doesn't seem to work on them. Moreover, I have compared one of the compressed files in Super Rush to its equivalent in Aces in a hex editor and it seems the initial byte is indeed different, indicating a different compression type. For that game, the magic number is indeed 50, but for the this one it's 94. I have attached a sample file from this game in hopes of figuring out how to decompress it like the other game's. msg_kernel.zip Edited February 20Feb 20 by PaperSplash Link formatting.
February 20Feb 20 Author Update: Apparently the compression algorithm for this game is just LZ4, as documented in this ZenHAX topic. For some reason, I didn't see it when I was searching earlier... Update 2: Despite attempting to use the QuickBMS script for LZ4 compression shared in that topic, I only see garbled text upon opening the resulting decompressed file, even though it's supposed to be a text file. Not sure what I'm doing wrong, if anything. Is it possible that script just doesn't work on this file? I also reached out to @LolHacksRule, who originally made that previous topic and did hear back, but unless I misunderstood, LHR doesn't seem to remember anything... msg_kernel_dec.zip Edited February 20Feb 20 by PaperSplash New update.

He provided decoded files. If the results don't please you try CyberChef, for example (just a wild guess because I don't know the language's country, well it's not Japanese...): edit: tried a dozens, forget about it. The solution is somewhere else. Edited February 22Feb 22 by shak-otay
March 3Mar 3 The game text is compressed using LZ4 and encrypted, so you can't view it. When you remove it, it looks like this. Edited March 3Mar 3 by Digote
