2009.10.15 This is a port of handheld PlayStation emulator psx4all to Linux for the Dingoo A320 (Dingux). It features MIPS to MIPS recompiling CPU emulation, and performance is acceptable, ranging from some 16-20 FPS in Gran Turismo to about 60 FPS in Tetris Plus (with some tweaks). Sound works in principle, but slows down emulation considerably, which is why I have not compiled it into the default build ("psx4all"). For those who want to try it, however, a version with a working SPU ("psx4all_sound") is provided as well. To use the emulator, simply drop it into a directory on your SD card and add "psx4all" to whatever launcher application you are using. It is possible to run games with the integrated high-level BIOS emulation, but compatibility is so-so. It is thus highly recommended to use a PlayStation BIOS image, which psx4all expects to be situated in the same directory and to be named "scph1001.bin". psx4all is able to use PlayStation games in BIN format (2352 byte raw sectors, file extension ".bin") and is also able to load files in the compressed CBIN format (file extension ".cbn"), which is very similar to the well-known CISO format, but uses a different sector size. A tool called "cbin" is supplied with the emulator that is able to convert BIN format images to CBN files. (Precompiled binaries are shipped for Mac OS X and Linux/i386; the source code should be trivial to compile on whatever system you are using; it only depends on zlib.) Memory cards are supported and need to be named mcd001.mcr and mcd002.mcr for Slot 1 and Slot 2, respectively. If these files do not exist, psx4all will create them. The emulator is controlled through a menu system. The cursor is moved with the Up and Down buttons, selections are made using the B button. The B button also toggles options. Numerical parameters can be changed using Left and Right. L always takes you back to the previous menu. Graphics Options : I don′t know the meaning of all these options either, so I will stick to those that I know and consider useful, or that I have added myself. Show FPSwhether or not to show the frame rate statstics on top of the screen Frame SkipFrameskipping can speed up emulation considerably, but will lead to choppy graphics and in many cases glitches. It is currently your best option to get full-speed or near full-speed emulation on many games, though. 2/3 frameskip appears to work best for most cases. 1/2 almost always causes severe problems. Cycle MultiplierIncreasing the cycle multiplier makes the emulated PlayStation hardware run faster relative to its CPU. This can help speed up games that don′t use the CPU much and mostly idle around waiting for the next frame. In other cases, it will not make a difference, or even make the game slower. Don′t be fooled by the increased frame rate! If the CPU is too slow to keep up, a high frame rate will be of no consequence. Frameskip: ....These option allow you to fine-tune the frameskipping behavior. When frameskipping causes glitches you can turn it off for certain parts of the graphics emulation instead of turning it off completely. Wall Clock TimingThis option is experimental, and I′m not quite sure if it is useful at all. It causes the hardware timing to be based on real-world ("wall clock") time instead of the cycle count of the emulated CPU. Its effect and its problems are very similar to that of the Cycle Multiplier option, but it locks the framerate to what it would be in real life. Sound Options : The only option is to turn the sound on and off. And that only works in the SPU build ("psx4all_sound"). File Options : Save Game StateFreezes the emulated system and dumps its state into a file that can be reloaded later. Files are named after the game disc image, with a dash, a four-figure counter and the extension ".svs" added. Don′t rename them, or psx4all won′t know what disc image to use when loading them. Load Game StateRestores a saved state. Load A GameBoots a CD image via the original PlayStation BIOS. BIN and CBN images are supported, plus a couple of esoteric formats I have never heard of before. Load A Game Without BIOS Boots a CD image with high-level BIOS emulation enabled. The compatibility is lower compared to using the original BIOS, but indicated framerates are higher. Games don′t generally feel faster, though, so that may well be a bug. In-emulation button assignment is as follows: PlayStation buttonDingoo button(s) Left - Left Right - Right Up - Up Down - Down Triangle - X Square - Y Circle - A Cros - sB Start - Start Select - Select + Start L1 - L R1 - R L2 - Select + L R2 - Select + R FunctionDingoo buttons Return to MenuSelect + Y QuitSelect + X (press and hold) Increase FrameskipSelect + A Decrease FrameskipSelect + B Turn FPS display onSelect + Right Turn FPS display offSelect + Left Source code, Binary Releases, Changelog, and Bug Tracking : All of these can be found on the psx4all-dingoo page at github: http://github.com/uli/psx4all-dingoo/ You can also download a Dingux toolchain for Mac OS X there, should you need one.
