==General Information==
Unlike most of the emulators that are built by the community, DamonPS2 is developed by a commercial company called DamonPlay Technology Co., Ltd. in China, which made it a commercial product kind of similar to [[Bleem!]].
==Issues==
===Privacy Concerns===
DamonPS2 requires access to users personal data unrelated to emulation (eg. contacts and location data). And as of version 3.0 it requires constant internet connection, leaving a lot to speculate it is selling user's data to advertisers.
===Terrible User Experience===
As a commercial product, the purpose of it is to create revenue and to maximize revenue, the free version of DamonPS2 is plagued with in-app advertisements, and most of the functions locked, including important functions such as memory card saving, causing a terrible user experience.
Also, DamonPS2 have some abnormal behaviors during its operation, such as checking SoC thermal control policy.
==Controversy with PCSX2=Code Stealing===
The [[PCSX2]] team and others have accused the developers of DamonPS2 of using the code from the PCSX2 project and violating its GPL v2 license in a blog post.
The evidence provided by PCSX2 team include:<ref>https://pcsx2.net/286-the-pcsx2-team-s-statement-regarding-the-damonps2-emulator.html</ref>
* GameIndex.dbf file distributed with the emulator contained patches that were specific to PCSX2；PCSX2.* CDVD strings, such as the message returned when a PSX/PSone disc is inserted in emulated PS2, is the same to PCSX2;.* Matching file structure and graphical output (including glitches) that mirrors GSdx in PCSX2 is found.* Instead of writing their own MIPS to ARM dynarec to replace PCSX2's, DamonPS2 uses an x86 to ARM dynarec on top of PCSX2's MIPS to x86.
On Baidu Tieba (a website similar to Reddit), DamonPS2 Develop Team did reply devs replied to such questions in represent of a corporation, DamonPS2 team replied as the accusations stating:<ref>https://tieba.baidu.com/p/5540262646</ref> (P.S. reference website is in Chinese)
* GameIndex.dbf do come from PCSX2, but such file is an index file that including game title names(even though the patches were still being used), so whatever, the emulator will contain such file and it will be similar to PCSX2 Gameindex.dbf by any mean. and such file has been this was removed as early (or baked into the binary) as in version 0.95;.* CDVD (contained in libserial.so) only used the same function names as PCSX2, the actual function is different, and such library has been removed as early (or baked into the binary) as in version 0.95;.* PCSX2 is a benchmark standard for DamonPS2 accuracy-test while developing, so such a standard made DamonPS2 behavior leaned to PCSX2, which they claim explain the identical graphical output as PCSX2;* The DamonPS2 development team repeatedly emphasized that the Chinese government’s copyright agency has reviewed its source code and the source code of its emulator has obtained copyright certification in China, And and copyright of all source code protected by the Chinese government.
DamonPS2 was taken off Google Play for a short time following a DMCA request from PCSX2. However, but because the PCSX2 development team is unable to provide convincing evidencehad posted publicly that they would be sending a DMCA request, and it shortly went back up afterward seems DamonPS2 pulled their emulator off the store before and Google has dismissed subsequent DMCA requests. Also, in the official forum of PCSX2, the PCSX2 development team refused to discuss the follow-up progress of during the matter in publicreview process.
