------------------------------------
c16 commodore c16/c116/c232/c264 (pal version)
plus4	commodore plus4 (ntsc version)
c364 commodore c364/v364 prototype (ntsc version)
------------------------------------
(beta version)

if the game runs to fast with the ntsc version, try the pal version!
flickering affects in one video version, try the other video version

c16(pal version, ntsc version?):
 design like the vc20/c64
 sequel to c64
 other keyboardlayout,
 worse soundchip,
 more colors, but no sprites,
 other tape and gameports plugs
 16 kbyte ram
 newer basic and kernal (ieee floppy support)

c116(pal version, ntsc version?):
 100% softwarecompatible to c16
 small and flat
 gummi keys

232:
 video system versions (?)
 plus4 case
 32 kbyte ram
 userport?, acia6551 chip?

264:
 video system versions (?)
 plus4 case
 64 kbyte ram
 userport?, acia6551 chip?

plus4(pal version, ntsc version?):
 in emu ntsc version!
 case like c116, but with normal keys
 64 kbyte ram
 userport
 build in additional rom with programs

c364 prototype:
 video system versions (?)
 like plus4, but with additional numeric keyblock
 slightly modified kernel rom
 build in speech hardware/rom

state
-----
rasterline based video system
 imperfect scrolling support (when 40 columns or 25 lines)
 lightpen support missing?
 should be enough for 95% of the games and programs
imperfect sound
keyboard, joystick 1 and 2
no speech hardware (c364)
simple tape support
serial bus
 simple disk drives
 no printer or other devices
expansion modules
 rom cartridges
 simple ieee488 floppy support (c1551 floppy disk drive)
 no other expansion modules
no userport (plus4)
 no rs232/v.24 interface
quickloader

some unsolved problems
 memory check by c16 kernel will not recognize more memory without restart of mess
 cpu clock switching/changing (overclocking should it be)

Keys
----
Some PC-Keyboards does not behave well when special two or more keys are
pressed at the same time
(with my keyboard printscreen clears the pressed pause key!)

shift-cbm switches between upper-only and normal character set
(when wrong characters on screen this can help)
run (shift-stop) loads first program from device 8 (dload"*) and starts it
stop-reset activates monitor (use x to leave it)

Tape
----
(DAC 1 volume in noise volume)
loading of wav, prg and prg files in zip archiv
commandline -cassette image
wav:
 8 or 16(not tested) bit, mono, 5000 Hz minimum
 has the same problems like an original tape drive (tone head must
 be adjusted to get working(no load error,...) wav-files)
zip:
 must be placed in current directory
 prg's are played in the order of the files in zip file

use LOAD or LOAD"" or LOAD"",1 for loading of normal programs
use LOAD"",1,1 for loading programs to their special address

several programs relies on more features
(loading other file types, writing, ...)

Discs
-----
only file load from drive 8 and 9 implemented
 loads file from rom directory (*.prg,*p00) (must NOT be specified on commandline)
 or file from d64 image (here also directory LOAD"$",8 supported)
use DLOAD"filename"
or LOAD"filename",8
or LOAD"filename",8,1 (for loading machine language programs at their address)
for loading
type RUN or the appropriate sys call to start them

several programs rely on more features
(loading other file types, writing, ...)

most games rely on starting own programs in the floppy drive
(and therefor cpu level emulation is needed)

Roms
----
.bin .rom .lo .hi .prg
files with boot-sign in it
  recogniced as roms

.prg files loaded at address in its first two bytes
.bin, .rom, .lo , .hi roms loaded to cs1 low, cs1 high, cs2 low, cs2 high
 address accordingly to order in command line

Quickloader
-----------
.prg files supported
loads program into memory and sets program end pointer
(works with most programs)
program ready to get started with RUN
loads first rom when you press quickload key (f8)

when problems start with -log and look into error.log file
