- Menu: Don't include iNES header in menu-only binary to discourage accidental execution (requested by rainwarrior and dustmop)
- Menu: Display error if key block is missing a screenshot (requested by dustmop)
- autosubmulti: Map from mirroring to map mode bit 0 was backward (reported by RogerBidon)
- a53build: Prints exception message for each ROM that failed to load (requested by JRoatch)
- a53build: Paths are explicitly relative to config file's directory (requested by JRoatch)
- a53build: Config file can change path of menu binary
- a53build: Screenshot converter shares NES palette with savtool
- a53build: Filename of config file no longer hardcoded
- makefile: make dist builds and packages both the menu source and one or more collections
