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.
Posting a ZIP file on GitHub kinda defeats the purpose. You should change the git repository to contain the source and project files (but not binaries). The ZIP file can be uploaded on the Releases tab after you tag a release.
