Pokemon Mystery Dungeon: Red Rescue Team; How to save on a flash card?

So normally whenever a rom can't save on my GBA flash card i use IPS patches to fix it. Sometimes i can't find the right patch, and i give up. But i'd really, really like to play this game on my GBA.So, if anybody could help me out here and either tell me a way how i can make the rom still save, or give me a working IPS patch. I've tried a lot of IPS patches for this game and none of them seem to work, so don't just get a link and post it here please. I'd appreciate it if you test the patch before telling me it works.So, can anybody please help me out here?Thanks.

Fixed it, finally.For anyone who would like to know, here is how i did it.First i used an ips patch to patch the rom. You can use any ips patcher for this like Lunar IPS or GBATA.After this i had to SRAM patch the rom as well. You can do this using GBATA. It has a built-in SRAM patcher.Good luck!
