I'm not sure what I'm doing wrong. I used the Mame Compiler 64 to compile 165 with no issues, but when trying to compile 179, nothing works. First when trying to apply the patch, I get "PatchDiff(): The system cannot find the file specified" (even though the Diff Patch File path is correct). Ignoring that, if I try to compile without the patch, I get "CompileMame(): The system cannot find the file specified" Under General Options, my paths look right: they're the defaults, and I've downloaded the MAME source and the build tools, etc. I've tried clean compile checked and unchecked and no love.
I'm sure I'm missing something simple, but I have no idea what it is. Any suggestions? (This is on Windows 10 running on an older i7.) Thanks!
