Why

You might already be happy with your choice of an OC emulator; after all, there is already a plenty of them. So why would you want to reconsider your life choices now all of a sudden? A fine question, indeed; perhaps, a list of features will persuade you.

Powered by ocelot-brain

At the heart of this emulator is ocelot-brain (uh, don't ask me), which is essentially the source code of OpenComputers stripped of everything Minecraft-specific and packaged as a Scala library. This makes Ocelot Desktop the most accurate emulator ever made. Your programs will run on the same version of Lua as used by the mod and have similar timings. The performance and memory constraints present in OC are also emulated.

Customizable setups

Computers can have the following components:

the 3 tiers of graphics cards
all kinds of network cards (wired, wireless)
a linked card
an internet card
a redstone card in the both tiers
a data card (again, you can pick any of the three tiers)
hard disks
a floppy disk (in T3+ computer cases only)

The choice is restricted by the tier of a computer case, just like in OpenComputers, to avoid building impossible configurations. Oh, did I forget to mention that Ocelot Desktop has both the CPUs and the APUs? Memory can likewise be installed according to your needs.

If one computer is not enough, you can add another one. Or two, or a thousand, as long as your host doesn't collapse under the load, of course. The network cards are there for a reason — these newly spawned machines can communicate with each other. And relays may help you manage the wired networks.

Or, instead of employing an army of computers, you might want to connect a dozen of screens to a single machine, like in the movies. No problem — we've got that covered, too.

Pretty graphical interface

A slick interface allows you to customize the setup to your liking. Add more computers, organize the connections between components, build complex setups, and manage your screen real estate to avoid distractions.

Many additional options are hidden in the context menu — try hitting the right mouse button on the various things. For example, components will let you copy their address to the clipboard, and right-clicking on the TPS counter on the bottom allows you to change the simulation speed.

The emulator uses hardware acceleration to offload the daunting task of rendering its interface to a specialized device, so make sure you have a OpenGL 2.1-capable graphics card.

Persistable workspaces

It would be sad if, after all the hard work you put into adjusting the workspace, you have to do that again. I mean, OpenComputers can persist its machines just fine, right? By basing the emulator on its code, we've essentially inherited the ability to save workspaces on the disk and load them afterwards.

Just in case, Ocelot Desktop will warn you if you smash the quit button without saving.

Cool features

A few smaller features are worth mentioning, too:

Screens are resizeable — drag the bottom-right corner.
Windows are labeled with the corresponding block's address; however, you can set a custom label — look for an option in the context menu.
The button in a computer case window shows the performance graphs: the used memory, processor time and call budget.
Hold the Ctrl key while dragging blocks to have them snap to the grid.
