REBUILDING FROM SOURCES:

AMIGA:

Prerequesites:

• Bebbo's amiga gcc compiler
• Windows
• python
• sox
• "bitplanelib.py" (asset conversion tool needs it) at https://github.com/jotd666/amiga68ktools.git

Build process:

• install above tools & adjust python paths
• make -f makefile.am

When changing asset-related data (since dependencies aren't good):

• To update the "graphics.68k" & "palette*.68k" files from "assets/amiga" subdir, just run the "convert_graphics.py" python script,
• To update sounds, use "convert_sounds.py" python script (audio) to create sound*.68k files.

NEO GEO:

Prerequesites:

• Windows
• NeoDev kit (Fabrice Martinez, Jeff Kurtz, et al)
  https://wiki.neogeodev.org/index.php?title=Development_tools

Build process:

• install NeoDev and set path accordingly
• clone repository
• make -f makefile.ng OUTPUT={cart|cd}
  • (OUTPUT defaults to cart)

Install process (MAME):

• make -f makefile.ng OUTPUT={cart|cd} MAMEDIR={mamedir} install
  • (mamedir defaults to '.')
• paste galaxian.xml into MAME's hash/neogeo.xml file

To run in MAME:

• cart : 'mame neogeo galaxian'
• cd : 'mame neocdz -cdrom roms/neocdz/galaxian.iso'
