Since I'm currently working on some Master System stuff and I've wanted to try and advance my C programming abilities for a while now, I've made a program to fix the Master System's checksum as the BIOS won't run the ROM otherwise, making it cumbersome for ROM hacking. Just drag a file and drop it, or include it in your batch scripts. https://www.dropbox.com/s/u2hsoje4c091uzo/MSChecksumFixer.zip?dl=0 https://github.com/Dandaman955/MSChecksumFixer Post any bugs you have here.
