Oricutron 0.9
-------------
(c)2009-2012 Peter Gordon (pete petergordon.org.uk)
This is a work in progress.
Current status
==============
6502: 100% done (apart from any unknown bugs :)
VIA: 95% done.
AY: 99% done.
Video: 100% done
Tape: 99% done (.TAP, .ORT and .WAV supported)
Disk: Reading/Writing sectors works. No track read/write.
Telestrat emulation is included, but is far from finished and doesn't currently
work well enough to be useful.

Thanks
======
Thanks to DBug and Twilighte for letting me distribute their demos and
games with Oricutron.
Thanks to DBug, Twilighte, Chema, kamelito, Yicker, JamesD, Algarbi, ibisum,
jede, thrust26 and everyone else for their help and feedback!
AVI export notes
================
The AVI export uses the MRLE codec. Your favourite player might not support
it, but MPlayer plays it, ffmpeg converts it and you can upload it directly
to youtube.
Note that the MRLE codec shows up some endian-issues on the Amiga OS4 port
of MPlayer, so it will sound crappy and have wrong colours until those bugs
are fixed :-(
Command line
============
You can specify certain options on the command line. All options have
both short and long versions. For example:
-mblah
or
--machine blah
Is the same thing. Note that the short version doesn't have a space, but
the long version does.
Here are all the options:
-m / --machine = Specify machine type. Valid types are:
"atmos" or "a" for Oric atmos
"oric1" or "1" for Oric-1
"o16k" for Oric-1 16k
"telestrat" or "t" for Telestrat
"pravetz", "pravetz8d" or "p" for Pravetz 8D
-d / --disk = Specify a disk image to use in drive 0
-t / --tape = Specify a tape image to use
-k / --drive = Specify a disk drive controller. Valid types are:
"microdisc" or "m" for Microdisc
"jasmin" or "j" for Jasmin
-s / --symbols = Load symbols from a file
-f / --fullscreen = Run oricutron fullscreen
-w / --window = Run oricutron in a window
-R / --rendermode = Render mode. Valid modes are:
"soft" for software rendering
"opengl" for OpenGL
-b / --debug = Start oricutron in the debugger
-r / --breakpoint = Set a breakpoint
-h / --help = Print command line help and quit
Examples:
oricutron --machine atmos --tape "tape files/foo.tap" --symbols "my
files/symbols" oricutron -m1 -tBUILD/foo.tap -sBUILD/symbols -b oricutron
--drive microdisc --disk demos/barbitoric.dsk --fullscreen oricutron
-ddemos/barbitoric.dsk -f

Monitor instructions
====================
In the monitor, number arguments are decimal by default, or prefixed with $ for
hex or % for binary. Pretty much everything is output in hex.
In most places where you can enter a number or address, you can pass a CPU or
VIA register. (VIA registers are prefixed with V, e.g. VDDRA). Anywhere you can
pass an address, you can also use a symbol.
Commands:
? - Help
a <addr> - Assemble
bc <bp id> - Clear breakpoint
bcm <bp id> - Clear mem breakpoint
bl - List breakpoints
blm - List mem breakpoints
bs <addr> - Set breakpoint
bsm <addr> [rwc] - Set mem breakpoint
bz - Zap breakpoints
bzm - Zap mem breakpoints
d <addr> - Disassemble
df <addr> <end> <file>- Disassemble to file
m <addr> - Dump memory
mm <addr> <value> - Modify memory
mw <addr> - Memory watch at addr
nl <file> - Load snapshot
ns <file> - Save snapshot
r <reg> <val> - Set <reg> to <val>
q, x or qm - Quit monitor
qe - Quit emulator
sa <name> <addr> - Add or move user symbol
sk <name> - Kill user symbol
sc - Symbols not case-sensitive
sC - Symbols case-sensitive
sl <file> - Load user symbols
sx <file> - Export user symbols
sz - Zap user symbols
wm <addr> <len> <file>- Write mem to disk
Breakpoints
===========
There are two types of breakpoints. "Normal" breakpoints trigger when the CPU is
about to execute an instruction at the breakpoint address. "Memory" breakpoints
trigger when the breakpoint address is accessed or modified.
There are three ways a memory breakpoint can be triggered; when the CPU is about
to read the address (r), and the CPU is about to write the address (w), or after
the value at the address changes for any reason (c).
You specify which ways you'd like the breakpoint to trigger when you set the
memory breakpoint:
bsm r $0c00 <-- Break when the CPU is about to read from $0c00
bsm rw $0c00 <-- Break when the CPU is about to access $0c00
bsm c $0c00 <-- Break after then contents of $0c00 change bsm rwc $0c00
<-- Break just before the CPU accesses $0c00, or just after it
changes for any reason.
