MAME
,Pang screenshot caption modification. MAME emulation is not “glitchy” anymore.
[[File:Mess sysinfo.png|thumb|upright=1.29|The MESS MAME system info box for the CPC6128]][[File:Mess gx4000 pang.png|thumb|upright=1.2|MESS MAME also has (still somewhat glitchy) support for the GX4000 and CPC+ series. Note the strange blue bar at the bottom in Here is shown ''[[Pang (cartridge)|Pang]]''for the GX4000.]]'''MESSMAME''' (Multi Multiple Arcade Machine Emulator Super System) is an a multi-platform emulator for vintage arcade games, home computers, gaming consoles, chess computers, and calculators, etc. It is a descendant of MAME 0.162 (released on May 27, 2015) merged the previously separate MAME arcade emulation project and just like MAMEMESS (Multi Emulator Super System) projects into one, so that a single executable now combines the most important goal emulation capabilities of MESS is highly accurate emulation, not speedpre-0. 162 MAME/MESS and MAME are mainly preservation projects that aim to reproduce the behaviour of the real hardware perfectly, so performance may be slightly worse than many dedicated CPC emulators.
==Command line argumentsInstallation==
On OS X, you can install MAME via [http://brew.sh/ Homebrew]: brew install mame On Windows and OS X, the MAME binary is called '''mame''', on Linux '''sdlmame'''. On some Linux distros such as Arch Linux you have to use absolute paths for disk images or ROMs because /usr/bin/sdlmame is a wrapper script that will cd to the directory with the MAME binary. Or you could simply skip the wrapper script and run /usr/share/sdlmame/sdlmame directly: alias mame=/usr/share/sdlmame/sdlmame ==Starting MAME;command line arguments; MAME menu; quitting==[[File:MAME menu CPC.png|thumb|upright|The MAME menu]]First get the [[Media:CPC_ROMs_for_MAME.zip|CPC ROMs for MAME]] and unzip them into the MAME roms folder. Typical command line to start MAME in CPC mode (windowed mode and with a disc inserted in drive A): mame cpc6128 -skip_gameinfo -window -flop1 disk.dsk Supported CPC models are cpc464, cpc464p, cpc664, cpc6128, cpc6128p, gx4000, cpc6128f (French), cpc6128s (Swedish), and the clones kccomp ([[KC Compact]]) and al520ex ([[Aleste 520EX]]; hold Shift during boot to go to Basic). Press ''Scroll Lock'' to toggle partial keyboard emulation mode. Now you can use ''P'' to pause MAME, ''Tab'' to enter the MAME menu, and ''Escape'' to quit MAME. ''Alt-Return'' toggles fullscreen mode. (See also [http://docs.mamedev.org/usingmame/defaultkeys.html default keys].) You can use the "-ab" commandline option to type text into MAME, e.g. mame cpc6128 -flop1 disk.dsk -ab "run\"disc\n"will boot the disc. ===Device options for the CPC from [http://www.progettoemma.net/mess/extra.html sysinfo.dat]===

You can use zipped disk images too. If there is more than one DSK image in the zip file, treat the zip file like a directory, e.g.
mame cpc6128 -flop1 disk.zip/disk0.dsk ===Python script to start MAME in CPC mode===On Linux, you can also set your file manager (e.g. Nautilus or Konqueror) to open .dsk files with the following Python script:<pre>#!/usr/bin/env python # Call as# "cpc" : emulated keyboard# "cpcn" : natural import os, os.path, zipfilefrom sys import argv if 'cpcn' in argv[0]: nat = '-natural'else: nat = '' s = "/usr/share/sdlmame/sdlmame cpc6128 -skip_gameinfo -window %s -keymap -keymap_file /usr/share/sdlmame/keymaps/km_de_LINUX.map" % nat def checkzip(t): "Check if file is a ZIP file; use the first file in the archive" if t[-4:].lower() == '.zip': a = zipfile.ZipFile(t).namelist() t = os.path.join(t, a[0]) return t if len(argv) > 1: for x in range(1, len(argv)): s += ' -flop%u "%s"' % (x, checkzip(argv[x]))os.system(s)</pre>This script should open a MAME window with the disc inserted in drive A. (Note that this also selects the German keymap.) You can also use this to open ZIP files containing disc images, e.g. "cpc mydisc.zip" will try to insert the first file in the ZIP archive. ==GUI front-ends==[[File:Mameui.png|thumb|MAMEUI64 on Windows]] Several GUI front-ends for MAME/MESS exist for Windows, Linux, and OS X: *[http://www.mameui.info/ MAMEUI64] (Windows)*[http://qmc2.arcadehits.net/ QMC2] (Windows, OS X, Linux)
==Keyboard layouts==
* '''emulated''' (the default; keys are assigned based on key position on the emulated hardware)
* '''natural''' (command line option "-natural"; based on the character generated by a key, e.g. pressing "z" will always generate a "z" on the emulated system)
To use a German keyboard in emulated keyboard mode, start MESS MAME e.g. with (key map path on Linux): sdlmess mame cpc6128 -keymap -keymap_file /usr/share/sdlmesssdlmame/keymaps/km-dekm_de_LINUX.txtmap
You can also put these settings in your mame.ini like this: keymap 1 keymap_file /usr/share/sdlmame/keymaps/km_de_LINUX.map In emulated mode, keys can also be remapped in the emulator menu. First press ''Scroll Lock'' to enable the MESS MAME control keys, then ''Tab'' to open the menu, and finally select ''Input (this system)''. ''Return, Esc'' clears an assigned key.
Note that the ''Delete'' and ''Backspace'' keys are swapped on the emulated keyboard because of the CPC keyboard layout. So you may want to reassign those. Escape on the CPC is mapped to the key left of "1" on the PC keyboard. Alt-Enter switches between windowed and full screen mode.
==CPC artwork==
[[File:MAME with CPC artwork.png|thumb|MAME window with monitor type set to green and optional CPC artwork]]
You can add optional bezel artwork to MAME to simulate a CPC monitor:
*[[Media:Cpc6128 mame artwork.zip|MAME artwork]] (CPC6128/GT65 bezel)
Rename this file to cpc6128.zip and put it in MAME's artwork folder (~/.mame/artwork/ on Linux).
==ROMs and extension hardware==
===General notes about MAME and ROMs often only work with a specific version of MESS. This does not seem to affect CPC ROMs, but other systems sometimes give an error message when ROM filenames or checksums do not match what MESS expected.===
You can get a list of slot options with
These are (as of MESS MAME 0.159168):

===Loading external ROMs===
The ROM Box expansion can be used to load external ROMs such as [[MAXAM]]:
Up to 8 external ROMs (-rom1 to -rom8) are supported this way.

==CRT simulation==
[[File:Cpc shader mess.png|thumb|upright=1.5|GLSL shader example]][[File:Cpc hlsl shader mess MAME BGFX Linux detail.png|thumb|HLSL "1980s" BGFX output with default shader (detail)settings]]Like MAME, MESS can use shaders to simulate typical CRT graphics artifacts such as scanlines, colors bleeding into each other, jitter, and display curvature. This involves editing mess ===BGFX=== The easiest way to do this (works on Windows, OS X, and Linux) since MAME 0.172 is to enable [https://github.com/bkaradzic/bgfx BGFX] video output: Put this in your mame.ini : video bgfx bgfx_screen_chains hlsl (or umeYou may also have to set bgfx_path to the bgfx directory if MAME cannot find the shaders.ini ) Check with F11 if you use UMEstill get 100% performance. If not, adjust frame skip with F8/F9. Also, if you press the tilde (~) and then cursor up/down, you can adjust the shader settings (they are also under Slider Controls in the MAME menu).These are not saved at the moment though.[http://docs.mamedev.org/advanced/bgfx.html] If you edit bgfx/chains/hlsl.json in a text editor, you can change the default values. E.g., to reduce the Moiré pattern, search for "Shadow Mask Amount" and change it to: "default": 0.20 ===HLSL and GLSL===[[File:Cpc hlsl shader mess detail.png|thumb|HLSL "1980s" shader (Windows); MAME config used is on image description page]]
*Windows (using HLSL shaders)

==Remaining issues with CPC emulation==
*MESS MAME may fail to read DSK images with certain kinds of copy protection. Speedlock seems to work fine though.*MESS MAME cannot write to disc images in DSK format; only MFI (MESS floppy image) and MFM (HxCFloppyEmulator floppy image) are supported for writing.*Some demo tricks may be broken in MESSMAME, e.g. overscan pictures are horizontally misaligned (i.e., shifted to the right).
*CPC+/GX4000 emulation still has some obvious graphics glitches.
*The emulated CPC464 has the AMSDOS ROM loaded which is a problem with early 464-only programs that rely on the 464's larger free memory.
