Tip: Using Lunar Magic's "Change Properties in Sprite Header" dialogue, you can adjust the sprite slots in which sprites can spawn. For example, by using a sprite memory setting that doesn't use slot 07, you can easily prevent Reznor breaks in your hack.
to apply patches, type cmd.exe in the run program, then drag and drop xkas, then press space, then drag and drop the patch, then press space again, then drag and drop your rom, then press enter, and you are done! now you applied a patch with xkas
For those who can't figure out how to use this, you need a copy of the command prompt .exe file (cmd.exe) in the SAME folder as xkas. You open cmd.exe, NOT xkas. In the command window, type "xkas (file name) (patch name)"...without quotes and parentheses, of course.
Hopefully, this will clear up any issues people are having. DOS is a lost art these days, it seems...
