Oricutron 0.8 ------------- (c)2009-2011 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: ".TAP" file support (no WAV yet, reading only) 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. Credits ======= Programming ----------- Peter Gordon Additional Programming ---------------------- Francois Revol Alexandre Devert Stefan Haubenthal Ibisum Kamel Biskri Amiga & Windows ports --------------------- Peter Gordon MacOS X port ------------ Francois Revol Kamel Biskri MorphOS & AROS port ------------------- Stefan Haubenthal Linux port ---------- Francois Revol Ibisum Alexandre Devert Pandora port ------------ Ibisum 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 -b / --debug = Start oricutron in the debugger -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 Keys ==== In emulator ----------- F1 - Bring up the menu F2 - Go to debugger/monitor F3 - Reset button (NMI) F4 - Hard reset Shift+F4 - Jasmin reset F5 - Toggle FPS F6 - Toggle warp speed F7 - Save all modified disks Shift+F7 - Save all modified disks to new disk images F10 - Start/Stop AVI capture Help - Show guide In menus -------- Cursors - Navigate Enter - Perform option Backspace - Go back Escape - Exit menus (or use the mouse) In Debugger/Monitor ------------------- F2 - Return to the emulator F3 - Toggle console/debug output/memwatch F4 - Toggle VIA/AY information F9 - Reset cycle count F10 - Step over code F11 - Step over code without tracing into subroutines. F12 - Skip instruction In the console: --------------- Up/Down - Command history In memwatch: ------------ Up/Down - Scroll (+shift for page up/down) Page Up/Page Down - Page up/down Hex digits - Enter address S - Toggle split mode Tab - Switch windows in split mode 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 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.
