So, during my first playthrough of the Ver. A Vaisaga hack for SRW OG2, I encountered a rather unfortunate bug in Stage 42. People who have played OG2 will remember that Alchemie (known as Alfimi in the English release) will join your team with her mech, the Personalichkeit, after you defeat her in that stage, and she will remain an ally for the Stage 43 if you managed to unlock it.

Well, in the aforementioned hack, a bug causes the Personalichkeit to vanish from the map after you defeat her. And while Alchemie will appear in the intermission menu following that stage, the Personalichkeit does not. As a result, while the game can still be beaten, she will remain unplayable for the final stage.

However, I happened to find a list of several Codebreaker codes for OG2 on the internet. And with a little bit of reverse-engineering the hexadecimal values, I found a way to restore the Personalichkeit for use in Stage 43. And now I’m going to explain how YOU can easily fix this glitch as well so that Alchemie can fight alongside your team in the final battle against the Einst.

A few things to note before we begin

• This method has been tested to work with the 2.8 and 2.9 versions of the Vaisaga Ver. A hack. Any version prior to these two should still be compatible with the following method, but I cannot personally speak as to that.
• This bugfix was created on a Windows computer with the mGBA Gameboy Advance Emulator. Using a Mac/Linux and/or a different emulator will probably require some alteration to the steps below.
• Using this method will make the Schutzwald and the Mind Blast weapon unusable in the final stage. I’m just not knowledgeable enough with hexa codes to create a new slot for the Lichkeit, so I had to replace an already existing mech.

The process

1. BEFORE ANYTHING ELSE!
   Go into the folder where your “.sav” file for OG2 Ver. A is and make a copy of it. This way you can restore your save data in case anything goes wrong.
2. Create a new Notepad file, copy and paste the highlighted code below into that file, and save it with the “.cheats” extension.
   • (Note: You make the file name anything you want, but you MUST save it using the “.cheats” extension.)

3. Start up OG2 Ver. A and load your save file for Stage 42’s Intermission.
4. Go to the Weapons (武器) tab, select Equip (選捩), then select the Schutzwald (シュッツバルト) and equip it with the Mind Blast (マインドブラスト). Save the game afterwards.
5. Go to the mGBA’s “Tools” tab, select “Cheats“, and Load the “.cheats” file you made earlier. The first five cheats should be On, and the latter five Off.
6. Close the cheats window, soft-reset the game, and re-load your save file.
   • When you check your Mechs tab, you should run across the Personalichkeit with all four of it’s weapons. If you see it with only part of it’s HP, don’t worry. This will fix itself when you begin the final stage.
7. Upgrade and equip it how you see fit, then when your preparations are complete, start the last stage. The Personalichkeit will now be properly deployed and ready to be used!
8. After saving beating the final stage and watching the credits, BEFORE you save your clear data, open the Cheats menu, turn OFF the first five cheats and turn ON the other five. Then close the cheats menu and save your clear data.
   • This will restore the Schutzwald and its weapons for use in future playthroughs.
