[bug#73770] [PATCH 0/2] Add freedisksysrom

[Maxim Cournoyer]

This is a free BIOS implementation of the old Nintendo Famicom (NES) that
replaces the nonfree, firmware blob 'disksys.rom' (extracted from the actual
device).  It is useful with NES emulators such as jg-nestopia.

Maxim Cournoyer (2):
  gnu: Add asm6f.
  gnu: Add freedisksysrom.

Perhaps we should add some dashes to make it "free-disksys-rom"?  I
wouldn't split "disk" and "sys" despite the camel case, but I'm in the
mood for kebab otherwise.

More importantly, is it expected that users can just install the
package and run with it or are extra steps needed to import it into jg
et al.?

Cheers
