Oni 2 (Angel Studios) Layout Patch Tool
by Iritscen

Requirements:
- The contents of this folder
- An ISO of Oni 2 (Angel Studios) for the PlayStation 2

The purpose of this tool is to allow you to enable the hidden levels, known as layouts, on the ISO.  Once you patch the ISO with this tool, the unlocked layouts will appear in the Load Game menu.  Since Oni 2 only allows 63 layouts to be active at once, and there are 95 in total, you have to choose if you want the first 63 layouts or the remaining 32 to be enabled.

Simply call this tool from the command line, e.g.:
Windows
cd path\to\oni2aslpt\
o2aslpt.bat "C:\path\to\oni2dev_ps2.iso"

Mac
cd /path/to/oni2aslpt/
bash o2aslpt.sh "/path/to/oni2dev_ps2.iso"

The name of the ISO you provide is not important, but it must be an original unmodified ISO.  A patched version of the ISO, named appropriately, will appear in this folder when the process is complete.
