Okay I'm new to this whole R4 and stuff but I got a question; I recently brought a R4 with a microsd card 4GB. And I put "kernel 1.30" on my micro sd card. So far 2 games have worked fine; Legend of Zelda Spirit Track and Super Robt Wars OG Frontier saga whatever its called. Both games play and save perfectly fine. However I tried putting the phoenix wright game series all save/load files either got corrupted and deleted. So I decided to put different games, but every other game kept getting the save file error and load file error crap. So I was wondering if I were to put a older version of kernel lets say v1.18 (from R4DS,com) would my spirit track file get corrupted or would it work perfectly since I started the game from the newest kernal version? I just want to see if an older version allows older games work. But I dont want to ruin my save file since it took me a long time where I am now. xD Thanks for helping me.
