that would break TOS ,you should look into injecting your-self

I've tried to investigate a little with the updates and I found one patch file but I don't know how I can apply it in the script. Maybe I should try to install one base game + the update and dump this via NXDumpTool to see what's the differences but for now I realy haven't the time to make these tests.

The game "Layer Section _ Galactic Attack'S" is also intresting, it structure is different than the Cotton compilation but it also need more time for discovering if it's realy intresting to use this particular game or not for multi-disc games.

The stuff I mentioned comparing the base/update is valid for all 3 games, it's nearly identical however both the .cue and .bin files do not match in hex, I could break apart the base NCA and see if there's new calls not in the first release - outside of that, I probably can't do anything else in terms of getting it to work myself

I assumed Layer Section/Galactic Attack was using the same setup - I have it on Xbox and didn't bother with the Switch version on the basis of that game being so similar. Multi disc support is a weird one, as functionally the games are identical and there's no swapping going on, it just resets the emulator

I'm wondering, this doesn't entirely pertain to the Switch version of these Saturn compilations (Although seemingly the ROM used in the Switch release is also encrypted), but I'm currently investigating the Steam release for Cotton 2 and Boomerang, as I wanted to try and either get the fan translation working with it (As using the Steam release would be a bit more legally accessible for others to play in English than hunting down a Saturn copy and dumping a ROM for it), or at least to get the Cotton2.bin and .cue files working in an external emulator (as seemingly they added an option to play as Appli), and it looks like the .ini files and game rom is encrypted on those releases of the games as well.

Attempting to use the Switch version's decrypted INI files will result in a CreateFile error that pops up on startup after the Sunrise logo. Might be possible to throw the game in a decompiler like Ghidra and poke at it to figure out how encryption is being done, but file formats and encryption in general seems like a topic that I'm currently not suited for. Has anyone else had better luck at this?

I also kind of found it a bit weird that slow motion in this compilation seems smoother (and the flashing effects are more rapid) than using slow motion through emulation, are they doing anything funny with time dilation in this release to keep the movement looking relatively smooth?

Figured I'd ask here since y'all have gotten far enough to load custom ROMs.

    If I am measuring someone's fitness then body fat percentage, various things from blood tests, resting heart rate, recovery rate, standing jump height, grip strength, possibly reaction time and more are factors that mean far more in my assessment of such things than weight and wasteline, though excess in those is by no means good

    Consuming 2000 extra kcal near a weigh measure, of course that will skew the results. It takes some time to remove that excess. Also, I want to get a clean measure, as good result as possible

    It all depends on your routine and your personality. In the gym there's a lot of machines, and trainers that can draw you an exercise plan and help you. I find it easier to exercise in the gym than at home, because at home I'm just delaying.
