==Running the game==
[[Image:Oni 2 - Shadow glitch.jpg|left|thumb|x220px|You will see issues like this with shadows unless you run PCSX2's renderer in Software mode.]]
[[Image:Oni 2 - Initial Attack.JPG|right|thumb|x220px|Characters will often be "blacked out" due to an issue with the lighting code. This is normal.]]
The ISO can be found on epforums.org (registration required) and is playable on a modded PS2 or in an emulator. The only mature PS2 emulator is PCSX2. Although PCSX2 is available for both Windows and macOS, the Mac version has poor performance and exhibits graphical glitches with this particular game. (Lighting problems occur even when playing on a PS2, so it's likely that graphics code was being worked on when this game build was produced.) Thus, if you are on a Mac, you will ideally want to use Boot Camp to run the game in PCSX2 for Windows. PCSX2 has also been reported to work on Macs running Windows within Parallels Desktop and VMware Fusion; it does not seem to run in Oracle VM VirtualBox, which has problems with 3D acceleration as of v5.1.

To prevent glitched shadows when playing Oni 2 in PCSX2, you need to switch the GSdx plugin to Software mode; this will severely cut performance compared to rendering in Hardware mode.

==Playing the levels==
Once Oni 2 is running, there is only one level available by choosing New Game. Fourteen additional levels, however, can be chosen from the Load Game menu. Levels can take a couple minutes to load, and some do not have loading screens, instead displaying a gray screen until they're done loading. Beyond this, an additional 80 layouts can be made available by patching the game disc ISO (instructions [[OBD:Oni2AS|HERE]], patch tool coming soon). "Layout" is the engine's term for what we would call a level or a room; some layouts are quite small, and others are large and complex. There is a total of 95 layouts in the game (including the 1 + 14 levels available normally). However, many of these (24, by one count) are nonfunctional. All the layouts are documented in their current functional or nonfunctional state on the [[../Levels|Levels]] page.

==Launch arguments==
Oni 2 accepts various launch arguments. To pass arguments to the game, you must use the package [http://websvn.chrilly.net/listing.php?repname=Oni2&path=%2Fps2launchargs%2F HERE]. Note that the patch tool provided in the previous section will allow you to play any level without using launch arguments.

The syntax for arguments which require a parameter, such as "-layout", is "-argument=parameter". The descriptions given below are taken verbatim from the game, and the effects are based on our testing.
