is there any kind of cheat or mod to complete the game easier? i've lost my save file after the game crashed and i don't want to do it all again
If your save is corrupted, you could try the 'Rescue' function.
1. Place your save (Game.rxdata) in the Rescue Folder.
2. Start the game.
3. Activate Debug mode (Down Arrow + X on the Title Screen).
4. Select Rescue on the Load Save screen.
Debug is a powerful tool, but it's also potentially very risky. If you can't rescue your save, I recommend sticking to giving yourself Rare Candies and other items to skip the grind, rather than trying to set Flags to re-create your save.
Note: Debug is known to cause at least one bug simply by activated (Typhlosion's unique bed scenes crash). You'll want to re-extract the Map files from the archive and overwrite.
