PearPC Trying to Sue CherryOS
Varg Vikernes writes "PearPC developers are taking in donations to sue Maui X-Stream, the developers of the MAC emulator software CherryOS. There have been allegations that CherryOS is nothing more than PearPC code, which is open-source, but with a GUI attached to it. One of the PearPC developers tried to get in contact with someone from Maui X-Stream, but eventually were told to "speak with an Attorney" about the allegations. "
It might be worthwhile mentioning that CherryOS (PearPC) is not a "MAC" (sic) emulator, but rather a general PowerPC architecture and motherboard emulator. PearPC presents itself as such. However, CherryOS markets and specifically targets itself at Mac OS X. Unfortunately, Apple's Mac OS X license agreement specifically states it can only be installed on an Apple-branded computer. Aside from the PearPC issues, CherryOS is a commercial product actively encouraging its users to break Apple's Mac OS X license agreement. And yes, this license agreement is binding: that's why no one makes clones. (And no, Apple "ROMs" are no longer required. Haven't been for ages.)
Funnily enough, Maui X-Stream president Jim Kartes said:
We are building an emulator like they are that uses Mac language. PearPC uses Mac language and next thing you know, they say we are using their code. This is a totally different architecture.
This comment makes no sense. "PearPC uses Mac language" has no meaning, and is, if anything, indicative of the fact that this company does not fundamentally understand the operation of innards of their product, which isn't surprising, since they didn't create it. PearPC is essentially a PowerPC motherboard emulator, which emulates a PowerPC processor, and various necessary elements of a PowerPC motherboard. I think what Kartes is trying to claim is that because PearPC and CherryOS do the same thing, it's no surprise that they'd appear similar. This claim is absurd, because the evidence is overwhelming that CherryOS is using PearPC as the emulation engine. CherryOS is essentially a graphical wrapper for PearPC, which does nothing more than pass instructions to PearPC and execute PearPC within itself. It tries to conceal, rather poorly, that PearPC is what's running underneath. Aside from the proof of very unique shared strings and symbols above, CherryOS also shares PearPC's featureset, or lack thereof in the case of support for sound and networking, and even PearPC's specific bugs. In sum, any claim that CherryOS and PearPC would share unique strings, variable names, and symbols simply because they're both emulators is ridiculous. Also, saying "Mac language" is really irrelevant because, aside from not making sense, PearPC (and CherryOS) doesn't have anything to do with the Mac or "Mac language". It's a *PowerPC* emulator. The fact that a Mac operating system runs on it is incidental; PearPC (and CherryOS) doesn't contain or use anything that could be referred to as "Mac language".

Below is a comprehensive collection of evidence, which runs the gamut from CherryOS including original PearPC graphics, extremely unique strings and error messages, debug code from PearPC, the same unique MAC address as PearPC's default network adapter (of which there are approximately 184884258895036416 different combinations), shared specific functionality, including bugs, and so on, not to mention code from other GPL projects:

...take a look at this. [In Internet time it's kinda old, March 16.]
Not retroactively, the GPL has a provision that says if you violate it, it permanently terminates the license. Since they violated the license, it's terminated. They have no valid license to distribute PearPC at all now. Even if they belatedly decided to comply with the terms of the GPL. It's too late.
