However, we recommend that you use the 720 P Parameter 3. Because neither SONY nor nVidia provides the Linux driver of the PS3 video card RSX, you cannot use the RSX hardware acceleration. If you set it to P, it may be a little slow, I still hope that SONY or nVidia will be able to provide RSX drivers for Linux or other experts to write these drivers one day.

The first is to analyze the file resources of the entire game. Generally, the game resources are not the common file types in Windows or Linux, some game manufacturers use third-party tools to process or develop their own file formats. For example, psarc format (playstation arch
Select Loops and menus
It is primarily used to create menus, which are displayed as a list of menu items in the form of a numerically ordered display on the standard error output, and a PS3 prompt is displayed to request user input (by default, the value of PS3 is "#?"). )。 The heart is PS3. After the prompt, the shell waits for the user to enter, the input

Optical discs are read using lasers to read data from a reflective surface of a laser that can be scattered or reflected, and a common disc is a DVD. Many systems say they are 32-bit or 64-bit, which refers to the number of bits in a register, address bus, or data bus. For example, on a 64-bit motherboard, the data bus (silver wire between components) has 64 lines that are side-by-end. Memory addresses are addressed in memory in the form of bit

supports a variety of rendering APIs (such as Direct3D 9 and OpenGL), and by default all shader programs are compiled into all supported renderers. You can point out the shader that needs to be compiled by #pragma only_renderers or #pragma exclude_ renderers directive This is primarily useful in this case, you are explicitly using some material language features on some platforms that you know are impossible on some platforms

high GPU requirements.
Let's take a look at the two multi‑thread ogre architectures. The first is middle-level multithread.
As shown in, each entity to be rendered is copied into two copies. The main thread and the rendering thread alternately update and render two copies of the same entity, and synchronize at the end of one frame, this solution has reached the first goal but has not yet reached the second goal. At the same time, the maintenance of the two entities is relatively complex and can
newer ATRAC3 encoders offer better performance.
LP4 Mode
This vulnerability CES the data rate to 66 kbit/s (half that of LP2), partly by using joint stereo coding and a lowpass filter around 13.5 kHz. it allows 324 minutes to be recorded on an 80 minute MiniDisc, with the same padding required as LP2.
FFmpeg has an implementation [5] of an ATRAC3 decoder, which was converted to fixed precision and implemented in the Rockbox series of firmwares for ARM, Coldfire and classification. Real

Prompt
In linux, the prompt is usually $, which is already the root user #. This is related to the specific linux version. We can also set our prompt, such as adding the user name and time. In Linux with four prompts, PS1, PS2, PS3 and PS4. PS1 is the default prompt. For example, we need to change the user name to $. You can reset PS1, that is, PS1 = "/u $". If we want to add time, set to PS1 = "/u-/A $
