The meaning of shareware is that if you are using the program regularly, you should strongly consider to register the program. With registering means that you are actually buying the product.

The installation and use of this product is done completely under your own responsibility. Under no circumstances should the producers of this product be held responsible for any damages or costs, that this product in any way could cause you or your equipment.

 

Introduction

Welcome to the world of CCS64. This a software emulator of the Commodore 64 computer. You may say this is not the first program trying to emulate the C64. But this is planned to be the finale C64 emulator. I have worked in several years with this product, studying the C64 into its innermost secrets. This shareware version should run perfectly with all games or demos, even those using the 1541 disk drive.

 

Registration

As this is SHAREWARE, if you like and use this program you are supposed to register it. Of course you then will get a registered version of this program with additional features and bonuses. At the moment the register fee is 30 USD, or equal amount in EURO, GBP or SEK. Credit cards or CHEQUES can NOT be used. Please consult your local post office or bank for proper ways of sending money to Sweden.

Instructions

Starting

WIN32 version:

To start the program just run the file named CCS.EXE.

Using

To do anything meaningful you should enter the program menu by pressing the key F9.

To use PC joysticks you have to calibrate them first. Calibration is selected from the submenu Options/Input in the menu.

If you have any problems with the settings and want the factory default settings back, just delete the 'C64.CFG' configuration file and it will be restored next time you run CCS64.

Menu

To use the Menu press F9 and then use the cursor keys to select. Use cursor right or enter to enter a choice. Use escape to go back to the previous menu from a submenu. Use cursor up or down to change selection. Use cursor left or right to change a value. Where specified you could also use the functions keys. When a selection can by applied, enter can also be used.

In a directory listing you could also use PageUp or PageDown to scroll faster through the selections. To get directly to the first filename which starts with a specific letter, you could press CTRL+letter.

In some menus you could also select an option by pressing the first letter in the option name, like S for the option "Select disk".

Keyboard

The keyboard is emulated almost like a real C64 keyboard and follows the C64 keyboard layout, except for these keys:

Multi-Play Over Internet

From the main menu, enter the submenu of Device 1 or 8-11. Enter the directory that contains the .T64/.D64/.PRG files that you want to be able to use for multi-play over Internet. Use cursor up/down keys to position on the "." directory, then press F3. Using the Kaillera client (http://www.kaillera.com) you can now connect to a server and from there either create a new game or join an existing one. Remember to not start your created game until enough people have joined. If you join an existing game, the game will start as soon as the game creator has started. To be able to join an existing game, you have to have started the multi-play menu from a directory which contains exactly the same file as the one that the game creator has.

During the Multiplay session, no menu setting can be reached. Therefore, remember to set correct settings for input devices etcetera before entering the multi-play menu. The multi-play session is ended by pressing either F9 or the F10 keys.

The following fast-keys work and are distributed to all players:

Alt+F5	Insert next .D64/.G64 disk image into device 8
Alt+F6	Insert previous .D64/.G64 disk image into device 8

The following fast-keys work and are only local to the current player:

Alt+F7	Select next input device/mode in C64 game port 1
Alt+F8	Select next input device/mode in C64 game port 2
Alt+F10	Exchange input device/mode settings between C64 game port 1 and 2

MC Monitor

The native MC Monitor can be invoked either from the Menu or by using the fast-key. As the monitor is native it doesn't affect the current emulated program in any way, all memory is untouched - unless you do a change yourself, that is. The monitor is exited with the Escape key. The following commands are supported:

Command syntax	Description
A <xxxx> <mnemonic>	Assemble. Example: A 1000 LDA #$09
BANK [<xx>]	Bank change 0-7 for different C64 MMU maps, 8-11 for 1541.
B	Show breakpoints
BA <xxxx> [RWE] [<xx>[-<yy>]]	Adds breakpoint at specified address, which is trigged when the address is Read, Written or Executed. Default is any access triggered. The trigg can also be limited within a range of data read/written. Example: BA D012 W F7-FF - This will only trigger the breakpoint whenever a program writes a value between F7 to FF to address D012.
BR <xx>	Remove the specified breakpoint. Example: BR 0 - This will remove the first breakpoint.
C <xxxx> <yyyy> <zzzz>	Compare memory.
D <xxxx> [<yyyy>]	Disassemble.
F <xxxx> <yyyy> <xx> ...	Fill memory with hex values or ascii strings. Example: F 1000 2000 "HELLO" 0D 0A
HD <xxxx> <yyyy> <string>	Hunt disassembly output textually for patterns. Wildcards are expressed with *. Example: HD A000 B000 "LDA*$*Y"
H <xxxx> <yyyy> <xx> ...	Hunt memory for hex values, ascii and wilds(XX). Example: H 1000 2000 10 XX "LEVEL"
I <xxxx> [<yyyy>]	Interpret memory as ascii.
L "<filename>" <xxxx> [<yyyy>]	Loads memory from binary file (not .prg). Example: L "Hack" 0800 1000
LP "<filename>" <xxxx> [<yyyy>]	Loads memory from binary program file (.prg). Example: LP "Hack.prg"
M <xxxx> [<yyyy>]	Shows memory as hex values.
P <xx>	Printer redirect. Redirects output of next D or M commands to the specified printer device (04-07).
Q <xxxx>	Quicktraces until the PC reaches a certain address.
R <reg> <xx..> ...	Register. Changes the contents of the named CPU register. Example: R PC FCE2 A 0 - This will set the PC to FCE2 and A to 0.
S "<filename>" <xxxx> <yyyy>	Saves memory to binary file (not .prg). Example: S "Picture" 2000 3F40
SP "<filename>" <xxxx> <yyyy>	Saves memory to binary program file (.prg). Example: SP "Demo.prg" 2000 3F40
T <xxxx> <yyyy> <zzzz>	Transfer memory. Copies the contents of a memory region into another.
W [<xxxx>]	Traces with singlestep.
X	Exits monitor.
: <xxxx> <xx> ...	Changes memory from hex values.
, <xxxx> <xx> ...	Changes memory from disassemble hex values.
* [<xx>]	Bank change 0-7 for different C64 MMU maps, 8-11 for 1541.
? <expression>	Evaluate a numeric expression and display the result in decimal and hexadecimal. The syntax of the expression is as follows: expr ::= hexnr | '$' hexnr | '#' decnr | '-' expr | expr '+' expr | expr '-' expr | expr '*' expr | expr '/' expr | expr '%' expr | '(' expr ')' Example: ?23+(56%7+55*(#23-7/3))

Some of the commands that produces several lines of output, like the M command, can be manually continued by scrolling up/down with cursor keys to the screen limits, or using page up/down keys. To get a free line to enter a new command, just press enter.

You can also get up on-line help and status page by pressing the function keys F1 to F4.

F1    -    Help
F2    -    VIC Status
F3    -    CIA1 Status
F4    -    CIA2 Status

You can swap to one of the 8 different session screens by pressing the Alt key together with one of the keys 1 to 8.

Alt + 1    - Session 1
Alt + 2    - Session 2
...
Alt + 8    - Session 8

Command-Line Options

To get a syntax description of the current available command-line options, just run the program from a command-window with the argument "?". Example:

CCS ?

This will probably give an output like: CCS [filename.{prg/p00/p01/t64/d64/g41/tap/crt}[,index]] [-cfg filename] [-fastload] [-normalload] [-autorun] [-manualrun] [-window] [-hardsid id]

Explanation:

[]                         - means that this option is optional and has not to be given.
{opt1,opt2,...}    - means one of the options.

filename.{prg/ p00/ p01/ t64/ d64/ g41/ tap/ crt}[,index]	A filename that describes a disk/tape/cartridge image to be loaded at the start of CCS64. The optional index tells which individual file inside of a disk/tape images that should be loaded (default is the first one). Example: mygame.d64,3
-cfg filename	Change the filename of the config file to be used (default is c64.cfg).
-fastload	Turns on the fastload feature when loading from disk or tape file images. Can be less accurate.
-normalload	Turns on the most accurate emulation of the disk drive when loading from disk or tape file images.
-autorun	Automatically starts the program that are loaded at the start of CCS64.
-manualrun	Do not start the program that are loaded at the start of CCS64.
-window	Force the emulator to use the windowed mode of the DirectX graphics display.
-hardsid id	Select the correct id for the HardSID sound card.

Example:

CCS C:\TheBestGames.D64,2 -window -autorun
- This will run CCS64 in windowed mode, and select the disk file image named TheBestGames.D64 as the current inserted floppy disk into disk drive with device 8, then load the 2nd file from the directory of that floppy disk and automatically start it.

Configuration

To change your configuration you could either use the program menu or edit the configuration file 'C64.CFG' manually.

Parameter name	Description
SCREENMODE=	If you change to a mode that doesn't work (or look nice) on your equipment, immediately (this is VERY important, or your equipment can be damaged) quit CCS64. Screen modes are now detected dynamically and are hardware/driver dependent.
SOUNDENABLE=	YES - Sound output on NO - Sound output off.
SAMPLEFREQ=	11111, 22222, 45454, or any other value, if your sound card can manage it.
SAMPLEBITS=	16 - Tries to use 16 bits samples, otherwise uses 8. 8 - 8 bits samples.
LOADPATH=	The path where you have your C64 games and demos.
RGBCOLOR0= RGBCOLOR1= ... RGBCOLOR15=	The RGB color values that should be used for emulating the C64 colors.

Common Problems

Some times special games on .D64 images will behave badly when you use the 'Run (Fast)' or 'Boot (Fast)' feature (this is default). To solve this problems do like this, use the 'Run (Normal)' or 'Boot (Normal)' features instead; otherwise, perform the following:
1) Reset the C64.
2) Enter menu (1541 Device 8) and select the correct .D64 (Insert Disk)
3) From the BASIC type:
LOAD"*",8,1

If you do not have a CD-ROM in your CD-drive or a disk in your disk drive, the emulator will hang up if you select this device in the menu. So please, always be sure that you have an initialized (sometimes you have to wait some seconds after instering it) CD-ROM in your CD-drive before trying to use the CD device from the menu.

The option load as Turbo tape should only be used when you get a message like "PRESS PLAY ON TAPE" on your C64-screen, and you're sure about that the second part should be loaded as turbo tape. Otherwise nothing useful will happen.

Note that when your sampling the C64's audio output to a .WAV file, the sample rate and bit resolution will be the same as selected in the C64.CFG file.

Note that on a German keyboard, the keys Y and Z will have changed place when using under CCS64.

When you use the Screen-Shot function, the image will be saved as CCS0.BMP, CCS1.BMP, CCS2.BMP, and so on.

When you use the Sound Sampling function, the audio file will be saved as CCS0.WAV, CCS1.WAV, CCS2.WAV, and so on.

When you use the printer emulation, the output will be saved as PRINTER4.TXT, PRINTER5.TXT, and so on.

When you use the HardSID support, the "Channels 1-4 Burst" and "Channels 1-4 Buffered" modes are recommended for faster CPUs; the "Channels 1-3 Burst & Channel 4 Emulated" mode is recommended for slower CPUs.

If you have some problems with the configuration of CCS64, and want to go back to the default settings, just delete the C64.CFG file from the CCS64 installation directory.

Using the emulator under Windows with old and out-dated sound drivers can sometimes cause the system to hang or for there to be no sound at all.

Notes

The C64 and 1541 roms is under copyright (C) by Commodore Business Machines. If you don't want these original roms you could replace the files KERNAL.ROM, BASIC.ROM, C1541.ROM and CHAR.ROM.
