US Bangai-O Spirits not saving

I downloaded the Bangai-O Spirits rom from this site, and I cannot get it to save, no matter what I do. Is anyone having similar problems to me?

What are you playing it on? A emulator or flashcart? If emulator, change the save type, if no$gba emulator, search the forums for "no$gba 2.6a" and select Auto option under NDS Cartridge Media in Emulation Options. If flashcart, update your firmware by going to http://www.linfoxdomain.com/ds/, download the latest firmware for your flashcart, extract it, get all the files and replace all the old firmware files with the new firmware files.

Wow that's strange. I just updated the firmware about 5 minutes ago (downloaded it from the official website), and it didn't fix the problem. I just downloaded the latest firmware from the website you sent me, and now it works! Strange how some things work out...Thanks alot!

Yeah, you probably didn't update the firmware properly.
