[Copied from RHDN]
Many vivosaurs unlocked in post-game are received directly, without having to clean anything. This certainly saves time, but it also means that there is no means of acquiring more than one of them, even if you go all the way through New Game + and get to the event again. This hack aims to rectify that. All such vivosaurs, along with the Chickens to save time, can now be bought as full-body fossils from the Donation Points staff member, for a whopping 0 DP. All you need to do is put your original vivosaur in the Bank, clean one of these fossils, and now you can have two, or three, or however many you want!
There is also an optional patch, which you use INSTEAD OF the main one. It does the same thing, but it also lets you buy the elusive Debug vivosaurs as well.
A word of warning: this patch should NOT be used for your main gameplay purposes, only to acquire the duplicates on your save (which you can then use with a normal ROM). This is not just because you can no longer acquire the DP-only vivosaurs, but also because making these vivosaurs revivable involved breaking the game in very specific ways, which do not mess up the intended process, but can very easily cause problems down the line.
