Bleach Dark Souls "data corrupted, now deleting everything"

well i am new to using roms and i am using Acekard 2.1

whenever i being playing Bleach: Dark Souls it says "saving data or something" i understand that this is when it is making a .sav file on the micro sd cards..am i right?

well after i go through some stuff and turn off the game and pley it again it says "data corrupted, deleting everything"
but when i downloaded the rom it came with a .sav file. was i suppost to paste that on the micro sd card?

and it came with a bunch of other files..
well i tried using a rom from somewhere else. the files had the ..r00 .r01 and so on until 20

so does anyone know what could going on?

thank you for your answers

 

Where did you download the ROM (the first time) from? The .r00 etc. is still a compressed archive.

Try updating your firmware. https://www.romulation.org/forum/index.php?topic=1462.0
