Linux Frequently Asked Questions with Answers Linux Frequently Asked Questions with Answers David Merrill [email protected] Robert Kiesling Revision History Revision 1.20 2001−12−04 Revised by: rk This is the list of Frequently Asked Questions for Linux, the free operating system kernel that runs on many modern computer systems. The kernel source code documentation says that Linux ``aims for POSIX compliance.'' Linux uses mostly free, GNU system utilities and application software, although commercial programs are available also. Originally written for 386/486/586 Intel/ISA bus machines, Linux versions exist for nearly every hardware platform in existence that is capable of running it. (Please refer to the question, ``What Is Linux?'' below.) This FAQ is meant to be read in conjunction with the Linux Documentation Project's HOWTO series. (``Where Are the Linux FTP Archives?'' and, ``Where Is the Documentation?'') The INFO−SHEET and META−FAQ also list sources of Linux information. Please read them, and, ``If this Document Still Hasn't Answered Your Question....'' before posting to a Usenet news group. You can also get Postscript, PDF, HTML, and SGML versions of this document. (``Formats in Which This FAQ Is Available.'') Linux Frequently Asked Questions with Answers is distributed under the terms of the GNU Free Documentation License.

    Snes9x: The Portable Super Nintendo Entertainment System Emulator ================================================================= v1.42 4-Dec-2003 ================= Home page: http://www.snes9x.com Contents ======== Changes Since Last Release Introduction What's Emulated What's Not What You Will Need Getting Started Game colour System Keyboard Controls Joystick Support Game Saving Netplay Support Cheat Support Super FX S-DD1 and SPC7110 S-RTC SA-1 C4 3dfx Support Problems With ROMs Sound Problems Converting ROM Images Speeding up the Emulation Getting Help Credits Changes Since Last Release ========================== Check the CHANGES file for a complete history of Snes9x changes between versions. Introduction ============ Snes9x is a portable, freeware Super Nintendo Entertainment System (SNES) emulator. It basically allows you to play most games designed for the SNES and Super Famicom Nintendo game systems on your PC or Workstation. The games include some real gems that were only ever released in Japan. Snes9x is the result of well over six years worth of part-time hacking, coding, recoding, debugging, etc. Snes9x is coded in C++, with three assembler CPU emulation cores on the i386 Linux, DOS and Windows ports. Snes9x is better than a real SNES: o Freeze a game at any position, then restore the game to that exact spot at a later date - ideal for saving a game just before a difficult bit. o Built-in cheat cartridge. o Built-in peripheral emulation. The SNES mouse, Multi-player 5 and SuperScope external add-ons are all emulated, they cost extra money with a real SNES. o Stereo sound - yes I know the SNES produced stereo sound, but who actually paid the inflated price for the special lead just so you could hear it? o No more cartridge contact cleaning! o Some SNES hardware features that be turned on and off during game play, games might be using one of these features to deliberately make a section of the game more difficult.
