Save editing to respawn bosses?

[Worly]

Is it possible to edit a save to respawn killed bosses (like the superbosses) I wanna mess around with killing them with various strats, but I would like to have all items available to do it (guess you could also edit in the items but that feels wrong)

You can simply edit save files. That should work with bosses. Use the simple old .sol-Editor. It's still working, but a bit glitched and error codes are in french.
So if you using that, then just create a new file, then open the save stand you wanna edit. Then it says you that the date is wrong, you just go on that box logo, rightclick > add > date.
Then you can edit the whole file. Don't reload the file after saving it's glitched, spam [x] when you done.

REMINDER FOR EDITING SAVE FILES IN GENERAL:
- the files located in the steam file are just backups and they get replaced everytime you run Mardek (I think? But Maybe just when you saving)
-> the real save files are located in [press WIN + r, enter '%appdata%', Macromedia\Flash Player and then click through
- MARDEK__sg_0.sol is the first save slot, when you go to the first page of all the saves so 0=first row, 1=second row ... last saved and stuff... yeah you don't have to mess around with them. Just don't open them next time you start Mardek and they get replaced, just always go to the pages and edit these files, it's easier
- always create backups by yourself
- don't forget to delete place holders (when you add items to your inventory and stuff like that)
