If you've got a slow system however, you may be able to speed up some applications by lowering the CPU speed to 60%-80% -ifreq <frequency> - Set interrupt frequency [50Hz] Default interrupt frequency is 50Hz for a PAL system, and 60Hz for an NTSC system. If you find most of your applications running a bit too slow, try using -ifreq 60 -sync <mode> - Select sync mode [1] 0 - Do not sync emulation 1 - Sync emulation on every VDP interrupt Using -sync 0 will let the emulator run at full speed. If you're not using games, you may want to use this option -expansion <mode> - Select expansion module emulation [0] 0 - Do not emulate expansion modules 1 - Emulate a roller controller with the mouse. Use your mouse buttons to press one of the first two roller controller buttons, use the ctrl and alt keys to press one of the second roller controller buttons 2 - Emulate a roller controller with an analogue joystick 3 - Emulate a driving module with an analogue joystick. Move your joystick forward to press the accelerator pedal, move your joystick to left or to the right to move the steering wheel, use the cursor keys or the joystick buttons to move the control stick 4 - Emulate a driving module with a mouse. Press a mouse button to press the accelerator pedal, use the cursor keys to move the control stick 5 - Emulate a super controller speed roller on both ports with a mouse. The third and fourth firing buttons of the super action controllers are always emulated. 6 - Emulate a speed roller on port 1 with a mouse 7 - Emulate a speed roller on port 2 with a mouse Please note that mouse support is currently only implemented in the MS-DOS version Controller options: -joystick <mode> - Select joystick mode [1] 0 - No joystick support 1 - Joystick support 2 - Joystick emulates game controller #2 3 - Joystick emulates game controller #1 In joystick mode 1, both the keyboard and the joystick emulate both ColecoVision game ports. For head to head games, you'll have to use either -joystick 2 or -joystick 1 -sensitivity <value> - Select mouse/joystick sensitivity [200] 1 - Maximum 1000 - Minimum Use this option if you're having trouble controlling the roller controller or driving module. Useful values are between 150 and 400 -swapbuttons <flags> - Swap/Do not swap buttons [0] 1 - Swap joystick buttons 2 - Swap keyboard buttons 4 - Swap mouse buttons For the joystick and the mouse, only buttons A and B are swapped -keypad <mode> - Select numeric keypad operation [0] 0 - Normal 1 - Reversed This option might be useful for games that use game controller overlays, like War Games -calibrate <mode> - Force/Do not force joystick calibration [0] 0 - Do not force joystick calibration 1 - Force joystick calibration Normally, the emulator loads the joystick settings from a file when it has been calibrated before. If you connected a new joystick, or you changed your joystick settings, and you're having trouble controlling your joystick, try using -calibrate 1 -keys <string> - Alter key mappings You can use the keys program to get the syntax necessary for your favourite key mapping Video options: -uperiod <value> - Set maximum number of interrupts per screen update [3] If you are using a slow system, you may prefer using -uperiod 2 or -uperiod 1. This will probably slow down emulation, but emulation will be much smoother -sprite <mode> - Select sprite emulation method [0] 0 - Show all sprites 1 - Don't show more than 4 sprites per row While many applications will suffer from heavy sprite flicker when using -sprite 1, some applications require the option for best display results -video <mode> - Select video mode [0] (Not implemented in Unix/X version) MS-DOS version: 0 - 320x200 1 - 256x192 2 - 256x240 Linux/SVGALib version: 0 - 320x200 1 - 320x240 Please note that video modes 1 and 2 may not work on every system -overscan <mode> - Emulate/Do not emulate overscan colour [1] (Not implemented in Unix/X version) 0 - Do not emulate overscan colour 1 - Emulate overscan colour Since overscan colours show quite differently on a television set compared to a VGA monitor, you may want to turn emulation of it off -chipset <value> - Select video chipset [1] (Linux/SVGALib only) 0 - VGA 1 - Autodetect If you are having video related problems, using -chipset 0 might solve your problems -shots <mode> - Select screen shots mode [0] (Not implemented in Unix/X version) 0 - Don't allow screen shots 1 - Allow screen shots A screen shot taken will have the filename CART.XXX where cart is the name of the cart loaded (e.g. DKONG), and XXX is the number of screen shots taken so far (e.g. 002). The screen shots will be in uncompressed windows bitmap format, 256x192 with 17 colours Sound options: -soundtrack <file> - Select file for sound logging [none] -sound <mode> - Select sound mode [255] MS-DOS version: 0 - No sound 1 - PC Speaker 2 - Adlib 3 - Adlib + SoundBlaster 4 - SoundBlaster 5 - GUS 6 - SB AWE32 255 - Detect The emulator uses the BLASTER environment variable to 'detect' the presence of a Sound Blaster. Some older Sound Blaster cards are not supported. Make sure your BLASTER setting is right or you may crash your system when running the emulator. The syntax of the BLASTER environment variable is: BLASTER=Aaaa Ii Dd Hh Tt Eeee, where aaa is the port address (default=220), i is the interrupt used (default=7 or 5, depending on the model you have), d is the DMA channel used (default=1), h is the high DMA channel used (SB16/AWE32 only, default=5), t is the model type (4=SB Pro, 5=SB16, 6=AWE32) and eee is the EMU baseport (AWE32 only, default=620). All other settings are ignored. If you have a GUS compatible sound card, make sure your ULTRASND environment variable is set correctly. It's syntax is: ULTRASND=Port,DMA,Record DMA,IRQ,MIDI IRQ. Only the Port parameter is used by the emulator. You might want to use -sound 3 if you have a slow system or a system with an 8-bit sound card Unix versions: 0 - No sound 1 - USS(/Lite) /dev/dsp 255 - Detect -reverb <level> - Select reverb send level (SB AWE32 only) [7] 0 - Minimum 100 - Maximum -chorus <level> - Select chorus send level (SB AWE32 only) [0] 0 - Minimum 100 - Maximum -stereo <level> - Select stereo panning level (SB AWE32 only) [0] 0 - Mono 100 - Maximum Useful values are from 0 to about 60 -soundquality <value> - Select sound quality (SoundBlaster and /dev/dsp only) [3] 1 - Lowest 5 - Highest While using higher sound qualities will improve sound output quite a lot, it will also cause a considerable slowdown -speakerchannels - Select PC Speaker channel list (PC Speaker <channel list> only) [4,3,2,1] If you don't have a sound card, and sound quality is extremely poor, try messing with this option a bit. Useful alternatives include 1,2,3 and 2,3,1 -volume <level> - Select initial volume [10] 0 - Silent 15 - Maximum Miscellaneous options: -shm <mode> - Use/Don't use MITSHM extensions for X [1] (X- Windows version only) 0 - Don't use SHM 1 - Use SHM Using SHM greatly speeds up emulation, but may not be compatible with your system -savecpu <mode> - Save/Don't save CPU when inactive [1] (X- Windows version only) 0 - Don't save CPU 1 - Save CPU Many command line options may be abbreviated. Use the -help options to get a list of currently supported abbreviations Soundtrack file format ====================== The soundtrack file format is as follows: Header: string 'Coleco Sound File',0x1A word Version number (LSB first, currently 0x101 for 1.01) byte Interrupt frequency in hertz Data: 0xFF Single interrupt mark 0xFE <n(byte)> Interrupt mark 0xFD <n(word)> Interrupt mark (LSB first) 0xFC <byte> Change interrupt frequency 0x00-0x7F Sound register write. High nibble is the register number, low nibble is the register value. Registers 0,2 and 4 are 12 bits wide (lower 8 bits are in second byte), all others are 4 bits wide Example: 13 FF 20 04 56 FD 05 01 45 06 ^--------------------------- Write 3 to register 1 ^------------------------ Interrupt ^--------------------- Write 004 to register 2 ^--------------- Write 6 to register 5 ^------------ 261 Interrupts ^--- Write 506 to register 4 Configuration files =================== The emulator loads two configuration files (if present) before it loads a cartridge rom: adamem.cfg or cvem.cfg located in the emulator's directory and CART.cfg (e.g. DKONG.cfg) located in the cartridge dump's directory. These are plain text files containing optional command line options. Options can be separated with spaces, tabs or returns. History ======= 0.2 15-11-1996 Completely rewrote VDP emulation engine; it now has support for sprite clipping, detection of 5th sprite in a row and non-standard screen modes, added support for GZIPped disk images, added ADAM printer control code emulation, added Unix/X and Linux/SVGALib ports, fixed some bugs 0.1 28-10-1996 Initial release Credits ======= - The Z80 emulator used is based on code written by Marat Fayzullin (fms@freeflight.com). The original Z80 emulator can be downloaded from http://freeflight.com/fms/CPUs/ - Joe Blenkle, Jim Marshall, Stephen Geyer, Grant Frost and Jim Notini were of invaluable help getting ADAM software and technical information. Thanks! - Todd A. Aiken spent a lot of time finding bugs, many of which would have never been fixed without his help. He also helped a lot improving the sound output - Martijn Zeedijk tested the GUS routines and helped me fix lots of bugs - Neal Danner provided me with the sound hardware related technical information on which the sound emulation code is based - The SB AWE32 routines are heavily based on 'The Unofficial Sound Blaster AWE32 Programming Guide' written by Vince Vu a.k.a. Judge Dredd. Thanks a million for writing this! - Some parts of the code were taken from Allegro. Allegro is a library for DJGPP written by Shawn Hargreaves. Allegro is available at ftp://x2ftp.oulu.fi/pub/msdos/programming/djgpp2 - ADAMEm MS-DOS was compiled using DJ Delorie's DJGPP v2.0. DJGPP is a 32 bit C compiler for MS-DOS.
