Installation:

GTK+2.0 is required. Since GTK+ could be configured differently on different systems, you will need to link Xe manually.

Easy Way (Installs to system directory):

1. login as root
2. 'make' to link the software
3. 'make install' will install it to the system directory

Manual way (Installs to system directory):

1. login as root
2. 'make' to link the software
3. 'mkdir /usr/local/lib/xe' to create system directory
4. 'mv modules /usr/local/lib/xe' to move modules to the modules directory
5. 'mv xerc /usr/local/lib/xe' to move configuration file to local directory
6. 'mv xe /usr/local/bin' to move xe into your path

Manual way (Installs to local directory):

1. 'make' to link the software
2. 'mkdir ~/.xe' to create local directory
3. 'mv modules ~/.xe' to move modules to the modules directory
4. 'mv xerc ~/.xe' to move configuration file to local directory
5. move 'xe' to your local bin directory

System Files: (in /usr/local/lib/xe)
bios/	store BIOS in this directory
modules/	store the modules in this directory
xerc	configuration file
xe.bg	wall paper (Image File: jpg, png, etc)
User Files: (in $HOME/.xe)
bios/	store BIOS in this directory
modules/	store the modules in this directory
saves/	Xe automatically saves back-up RAM in this directory
xerc	configuration file
xe.bg	wall paper (Image File: jpg, png, etc)

Notes:

• Neo Geo (and Neo CD) BIOS need to be in big-endian format. You can byte-swap using the command 'dd if=asia-s3.bin of=neogeo.rom conv=swab'
• Only the AES (Home System) BIOS is supported.
• 68K ROM data is stored in big-endian format.
• SPR ROM format is stored as Plane 1, Plane 0, Plane 3, Plane 2 (Same as Neo CD).
