If you don't use vim, and not develop in ubuntu, like me. When you make with 'make ARCH=native run mainargs=k', you maybe meet this question.

[qian@localhost fceux-am]$ make ARCH=native run mainargs=k
# Building fceux-run [native]
# Building am-archive [native]
# Building klib-archive [native]
# Creating image [native]
+ LD -> build/fceux-native

This happens because ./fceux-am/nes/gen/mario.c is empty. Look through the file ./fceux-am/nes/build-rom.py, you will find mario.c is converted by mario.nes with xdd program. If you develop in fedora, you just need sudo dnf in vim-common. xdd is included in this package.

it's xxd not xdd.it's a tool to make (or reverse) a hex dump.
Archlinux meets the same problem when trying to play mario, and yay -S xxd can solve.
