I just beat the hall of fame yesterday (March 15.) but I forgot that My DS Date was set to Feb 14 (i made a month mistake) so if anyone could please tell me the AR code to change the hall of fame debut to Mar 15. 2010 i would appreciate that.
Man, so many people trying to use AR to fix everything... Use Pokesav and just change the date that way. The only thing I find the AR good for is instant egg hatch, 1-hit kills in the battle tower, and that's pretty much it.
That is the part of the US pokesav that includes the hall of fame debut changer but not alot of features are on my version: Pokesav_HGSS-ENG-Ver.0.03 but do you have a US pokesav HG/SS that includes the 'records system edit' (at the top right)
I just tried using it with the HGSS one and it isn't enabled. However, you can use the Platinum version to strictly edit ONLY the Debut, save it, and then reload it through the HGSS editor and everything else is untouched. *Make a backup of your HGSS before you do this, in case you do it wrong.
Take your HGSS save. Load it through Pokesav Platinum. Change the Records Date. Save it. Now load it through Pokesav HGSS. Save it. Done. And yes, I did it just to test it out. It works.
