I got this patch for Hikari no 4 Senshi - Final Fantasy Gaiden from a chinese website and it has a leaf icon. I've tested it and it works on my EZ-Flash V+. I can load my saved game now.

I don't know how to read chinese but I can navigate through their website.
Here's the google-translated instructions on how to patch the rom:
Currently out of the village to look for Princess, the largest map of the fighting. Not found black.
Usage:
1, download attachments run the patch extract obtained from
2, click the lower right of the "patch"
3, select the game in order to ". Nds" as the suffix of the ROM file
4 to determine the replacement
I decided to overwrite my rom with this patch and now it works great so far.
To save your game, search for a man in a brown suit with a tall hat in town. He'll ask you first if you want to save yes or no. Then his second line will ask if you want to continue the game or not with a yes or no choices.
