oh wow, fast response, and thank you.
Almost any edit that I make will cause a corruption. For example, I first wanted to edit the level of my 1st pokemon, and it did not work. I then proceeded to edit more data (which I used for testing purposes), and it did not work. I am not able to edit anything without having a corrupt data. I do have a working back up.
If this counts, I used to use Pokesav with Pearl/Diamond in 2007 all the time by editing ANY amount of data with an R4 without any problems. I'm pretty sure I'm doing the same exact thing with HG/SS, but at the same time, I feel that I may be missing something.
*and to follow the guidelines of this board, I am not using these "hacked" pokemon for any wifi event or to flood the trade networks. Im using these customized pokemon offline and for my own use.
Thank you Evan, I appreciate your help.
