Recommended patch: https://glfs-book.github.io/slfs/download/p20-emu/p20-emu-d75a83-no-debug.patch
Recommended patch: https://glfs-book.github.io/slfs/download/p20-emu/p20-emu-d75a83-system-roms.patch
Apply a patch to build without any debugging information, which allows for a slightly faster binary:
patch -Np1 -i ../p20-emu-d75a83-no-debug.patch
Optionally, apply a patch to search for the ROMs in a system-wide location and not the current directory:
patch -Np1 -i ../p20-emu-d75a83-system-roms.patch
Install p20-emu by running the following command:
make Musashi/m68kops.h && make
Now, as the root user:
install -vDm755 emu /usr/bin/p20-emu
If you have applied the systemwide ROMs patch, install those ROMs
as the root user:
install -vDm644 ../U1{5,7}-MERGED.BIN -t /usr/share/p20-emu/
make Musashi/m68kops.h: This command explicitly generates a header file used during build time to avoid a race condition.
