no$psx
nocash Playstation PSone emulator by martin korth

My current monetary stats are that I've borrowed 200 euros to get the rent paid in April, and I'll need to do the same in May, too. Some small donations would really help to support the nocash projects. Big thanks to everybody who has already donated something. And very big thanks to people who donated even more than ten dollars!

The Program is intended to work out-of-the-box. There is no need for specific windows versions, special video drivers, obscure plug-ins, virtual CDROM drives, system BIOS, or tweaked per-game configurations.
The Emulation should be complete with all hardware features fully implemented and working, though as by now it wasn't tested with too many games, so there may be still some problems with other games (bug reports are welcome).
The BIOS is emulated via a BIOS-clone, which is free and faster than the original PSX-BIOS. There may be still some compatibilty issues (especially as most PSX games are applying patches to the original BIOS; the BIOS clone is reproducing known patches, but may fail on unknown ones). In case of problems, please use a copy of the original BIOS (with filename PSX-BIOS.ROM in no$psx folder), and please let me know if that is fixing problems with any games.
CDROMs are supported via complete disk images (in .CCD+IMG, .CDI, .CUE+BIN, .MDS+MDF, or .NRG format), via single-track images (.ISO files), or as raw executables (.EXE files). Decompressing .ECM and .CDZ files is supported. Subchannel data (for libcrypt'ed games) can be read from .SBI, .M3S, .SUB, .MDF files. Reading from real CDROM drives is also supported, but does require wnaspi32.dll (which appears to be a problem on WinNT/Win2K and higher).
Minimum Requirements are around 1-2 GHz on a Pentium 3, which is maybe fast or maybe not so fast (older PSX emulators are said to be working on 200MHz computers, on the other hand, I got told that no$psx is much faster than those old emulators... I've no clue how that is possible).
Debugging/Development functions include disassembler, debugger, profiler, code breakpoints, memory breakpoints, assembler, I/O map viewer, VRAM viewer, polygon viewer, TTY debug console window, and complete PSX hardware specs.

Hardware Donations
If you've some old PSX hardware that you want to get rid off, and that you want to donate for emulation and research purposes, some things that I am looking for would be:

  • SCPH-1040 Serial Link Cable (for testing max transfer rate; which is needed since games seem to autodetect that max rate)
  • SCPH-10180 I-Mode adaptor, and maybe an old I-Mode compatible mobile phone
  • SLEH-0005/SLUH-00017 Konami Lightgun (for testing if it's accuracy is really worse than Guncon)
  • SLPH-00100/SLUS-00063 Fishing Controller (ascii/agetec)
  • BANC-0001 Fishing Controller (Bandai)
  • HPS-97/HPS-98 Fishing Controller with attached plastic fish (Hori)
  • SCPH-1150 old analog joypad (with one vibration motor, with red/green led)
  • SCPH-1180 old analog joypad (without vibration motors, with red/green led)
  • Playstation 2 (for examining it's PS1-compatibility, and maybe PS2 emu)
  • One or two US or Japanese PSX CDROMs (for checking other regions)
  • Info on Asian Region (are there any differences to other regions?)

    • Note: shipping address would be in germany.
