Posted October 31, 2020 · Report post I run a program to check and recalculate EDC/ECC after I patch every PS1 rom, and in doing so I got this error which it seems prevented this. The game runs just fine on a modded PSP, so it probably didn't have malformed EDC/ECC to begin with, but I thought I'd let you know about this if you didn't know already. I'm not sure what it means but maybe it makes more sense to you. .\error_recalc.exe '.\Monster Tactics.iso' error: image not in 2352 byte sectors Share this post Link to post Share on other sites
