As of the Version 3 of the game, which spans up to chapter 15, hard mode only applies to chapters 7-10. Changes include--

- Harder Enemies (stats/levels)
- Changed enemy inventories
- More or less units allowed into battle
This is all so far as I can only auto implement hard mode into chapters with battle preparations. I decided not to add hard mode to chapters 14 and 15. However, as of chapter 16 and on, hard mode will be implemented.

In order to play hard mode, you must use the "Hard Mode/Unlocked Savestate.sgm" file that comes with the game. Load this savestate using VBA by either loading Tactics Universe and then going to File->Load save or renaming the file. If you game is called "Hack.gba" then you could rename the hard mode savestate file to "Hack1.gba", "Hack2.gba", etc., and then Press F# to load that state. If you renamed it Hack4.sgm, then you'd load savestate 4, because of the '4' at the end of the save name. Once you load this, start a new game and choose Siegfried's/Lyn's hard mode. You can do the same for Anakin's mode, however there is no hard mode programmed for that part of the game yet.
