What is hardware download mode and how does it work
Hardware download mode is a setting that affects games that download data from the graphics processor (GS)
Some PS2 games use a technique called GS Downloading, which means they transfer data from the main processor (EE) to the graphics processor (GS) in reverse order. This allows them to use the GS as a temporary storage or perform some calculations on the data. However, this technique is not well supported by modern GPUs and may cause slowdowns or glitches on emulators.
Hardware download mode can improve performance, but may also cause visual glitchesHardware download mode is a setting that can help you improve the performance of games that use GS Downloading, but it may also cause some visual glitches or errors. It basically changes how the emulator handles the data transfer between the EE and the GS. Depending on the game and the option you choose, you may see a significant boost in speed or a noticeable loss in quality.
Hardware download mode has four options: Accurate, Disable Readbacks, Unsynchronized, and Disable
Hardware download mode has four options that you can choose from in the AetherSX2 settings menu. Each option has its own advantages and disadvantages, and you may need to experiment with them to find the best one for your game. Here is a brief explanation of each option:
Accurate: This is the default and most compatible option. It tries to emulate the GS Downloading as accurately as possible, but it may be slow or cause stuttering on some devices. It is recommended for games that rely heavily on GS Downloading, such as Gran Turismo 4, Tekken 5, or Shadow of the Colossus.
Disable Readbacks: This option disables the readback of data from the GS to the EE. This means that the emulator will not check if the data transfer was successful or not. This can improve performance, but it may also cause some minor visual effects to be missing or incorrect. It is a fairly safe option for most games, and you may not notice any difference in quality.
Unsynchronized: This option makes the data transfer asynchronous, meaning that it will not wait for the GS to finish processing the data before sending more. This can boost performance significantly, but it may also cause random data or garbage to be returned to the EE. This can result in graphical glitches, crashes, or freezes. It is a risky option that should only be used for testing purposes or if you are desperate for speed.
Disable: This option completely disables the GS Downloading feature. This means that the emulator will ignore any requests to reverse the data transfer from the EE to the GS. This can improve performance, but it may also break some games that rely on GS Downloading for gameplay logic or graphics rendering. It is an experimental option that should only be used for games that do not use GS Downloading at all.
How to use hardware download mode for different games
Accurate mode is the default and most compatible option
As mentioned before, Accurate mode is the default option for hardware download mode. It is also the most compatible option, as it tries to emulate the GS Downloading as closely as possible. However, it may also be the slowest option, as it requires more processing power and memory bandwidth from your device. If you have a powerful device and want to play games that use GS Downloading extensively, such as Gran Turismo 4, Tekken 5, or Shadow of the Colossus, you should stick with Accurate mode.
Disable Readbacks mode is fairly safe and may boost performance with minor visual effects missing
If you want to improve performance without sacrificing too much quality, you can try Disable Readbacks mode. This option disables the readback of data from the GS to the EE, which can save some time and resources. However, it may also cause some minor visual effects to be missing or incorrect, such as shadows, reflections, or lighting. For most games, this option is fairly safe and you may not notice any difference in quality. Some examples of games that work well with Disable Readbacks mode are God of War, Kingdom Hearts, or Final Fantasy X.
Unsynchronized mode is risky and may return random data or crash the game
If you are feeling adventurous and want to squeeze every bit of speed out of your device, you can try Unsynchronized mode. This option makes the data transfer asynchronous, meaning that it will not wait for the GS to finish processing the data before sending more. This can boost performance significantly, but it may also cause random data or garbage to be returned to the EE. This can result in graphical glitches, crashes, or freezes. It is a risky option that should only be used for testing purposes or if you are desperate for speed. Some examples of games that may work with Unsynchronized mode are Dragon Ball Z: Budokai Tenkaichi 3, Resident Evil 4, or Ratchet & Clank.
Disable mode is experimental and may ignore requests to reverse data transfer
If you want to try something different and see what happens when you disable GS Downloading altogether, you can try Disable mode. This option completely disables the GS Downloading feature and ignores any requests to reverse the data transfer from the EE to the GS. This can improve performance, but it may also break some games that rely on GS Downloading for gameplay logic or graphics rendering. It is an experimental option that should only be used for games that do not use GS Downloading at all. Some examples of games that may work with Disable mode are Persona 4, Silent Hill 2, or Guitar Hero.

What are the benefits of hardware download mode?
Hardware download mode can improve the performance of games that use GS Downloading, which is a technique that transfers data from the main processor to the graphics processor in reverse order. Some games use this technique extensively, such as Gran Turismo 4, Tekken 5, or Shadow of the Colossus. By changing how the emulator handles this data transfer, you may see a significant boost in speed or a noticeable loss in quality.
How do I enable hardware download mode?
To enable hardware download mode, you need to go to the AetherSX2 settings menu and select the Graphics tab. There you will find the Hardware Download Mode option, which has four choices: Accurate, Disable Readbacks, Unsynchronized, and Disable. You can choose the one that suits your game and device best, or leave it at Accurate for the most compatible option.
Which games work best with hardware download mode?
There is no definitive answer to this question, as different games may react differently to hardware download mode. You may need to experiment with each option and see what works best for you. However, some general guidelines are:
If you want to play games that use GS Downloading extensively, such as Gran Turismo 4, Tekken 5, or Shadow of the Colossus, you should stick with Accurate mode.
If you want to improve performance without sacrificing too much quality, you can try Disable Readbacks mode. This option works well for most games, such as God of War, Kingdom Hearts, or Final Fantasy X.
