Anybody who purchased DDR Extreme US has noticed one overwhelming, glaring problem - there is no way to disable your pad corners during play. Interestingly, the option still exists in the engine if not in the interface. That option can still be set by directly editing the Extreme US save file. The instructions that follow are a guide to modifying your Extreme US game save using a Datel MAX Drive.
If you don't care about losing any existing scores or progress, you can download an already modified ExUS save from DDRFreak and transfer it to your memory card via the MAX drive, no editing required. You need only go through the process below if you want to maintain your already achieved scores and unlocks.
At some point, I'll do screenshots of everything, but I'm typing this from work where they typically frown on people messing about with PS2's.
Final disclaimers: If you mess up your save, it's not my fault. Always work with backups! Be sure to familiarize yourself with how the MAX Drive works before starting this process. And keep in mind that this procedure is only for DDR Extreme US game saves.
Having said all that...
1. Copy your Extreme US save to a second memory card that has nothing else on it. This isn't an entirely necessary step, but if you mess something up, you'll at least have the original save somewhere.
2. Power up your PS2 with the fresh memory card, the MAX Drive, and the MAX Drive PS2 disc inserted.
3. Go into the first option on the MAX Drive main menu. Set your memory card as your primary device.
4. Select the DDR Extreme System save file and copy it to the MAX Drive by selecting the "Copy" option at the top of the right pane.
5. Once the copy is complete, take out the MAX Drive and head to your PC.
6. Install the MAX Drive PC software if you haven't done so already.
7. After installation is complete, insert the MAX Drive into a USB port. A new drive should appear and will typically open automatically.
8. Copy the .MAX save file from the MAX Drive onto your desktop.
9. Use the MAX converter to convert the file from a MAX file to an XPS file. Save the XPS (don't change the core filename, though - make sure you only change the .MAX extension to .XPS).
10. Open the XPS in PS2SaveBuilder. PS2SB will show a list of files within the save. Right click the BASLUS-20916system entry and select Export. Save this file to your desktop.
11. Using a Hex editor (I used UltraEdit), open the BASLUS-20916system file.
12. Find positions 0x2E and 0x2F - this is very near the beginning of the file - and you should see that both locations have the value 01.
13. Change both 01 entries to 00.
14. Save your edited BASLUS-20916system file, overwriting the one you originally saved to the desktop.
15. Go back to PS2SaveBuilder and find the Add File menu item. Click it.
16. Select your newly modified BASLUS-20916system file.
17. Save the XPS file from PS2SaveBuilder, overwriting the XPS file you made during the MAX conversion.
18. Run the MAX converter and convert the .XPS back to .MAX.
19. Copy your new .MAX file back onto the MAX Drive, overwriting the file that was there originally.
20. Yank your MAX Drive and go back to your PS2.
21. Insert the MAX Drive into the PS2 USB slot, insert your memory card, and boot up with the MAX CD.
22. Once again, select the first option at the Main Menu.
23. Select the USB stick as your primary device.
24. Select the Extreme game save in the left pane.
25. In the right pane, select the Uncrush option. You will see that it then says "Uncrush to MC1". If it doesn't say that, you did something wrong.
26. Verify that you wish to Uncrush to MC1. At this point, the save will be written to your memory card.
27. Yank the MAX Drive, plug in your dance pad, boot up Extreme and dance with no more bothersome corners.
