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 (See NOTE2) -h / --help = Print command line help and quit --turbotape on|off = Enable or disable turbotape --lightpen on|off = Enable or disable lightpen --vsynchack on|off = Enable or disable VSync hack --scanlines on|off = Enable or disable scanline simulation --serial_address N = Set serial card base address to N (default is $31C) where N is decimal or hexadecimal within the range of $31c..$3fc (i.e. 796, 0x31c, $31C represent the same value) --serial <type> = Set serial card back-end emulation: 'none' - no serial 'loopback' - for testing - all TX data is returned to RX 'modem[:port]' - emulates com port with attached modem, only minimal AT command set is supported and data is redirected to TCP. Default port is 23 (telnet) 'com:115200,8,N,1,<device>' - use real or virtual <device> on host as emulated ACIA. Baudrate, data bits, parity and stop bits can be set as needed ex.: Windows: 'com:115200,8,N,1,COM1' Linux: 'com:19200,8,N,1,/dev/ttyS0' 'com:115200,8,N,1,/dev/ttyUSB0' NOTE: If you are not sure what machine or drive type is required for a disk or tape image, just pass the filename without any options and Oricutron will try and autodetect for you. NOTE2: List with many breakpoints can be loaded from command line. Use default switches -r or --breakpoint, but instead of an address, specify filename prefixed with ':'. The file is plain text file, which contains desired breakpoint-addresses - one per line using the same syntax as in the monitor. Breakpoints can be set with absolute addresses or with symbols (loaded with command line switches -s or --symbols). Examples: oricutron tapes/tape_image.tap oricutron disks/disk_image.dsk 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 oricutron --turbotape off tapes/hobbit.tap oricutron -s myproject.sym -r :myprojectbp.txt 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 F8 - Toggle fullscreen F9 - Save tape output F10 - Start/Stop AVI capture F11 - Copy text screen to clipboard (BeOS, Linux & Windows) F12 - Paste (BeOS, Linux & Windows) Help - Show guide (Amiga, MorphOS and AROS) AltGr - Additional modifier In menus -------- Cursors - Navigate Enter - Perform option Backspace - Go back Escape - Exit menus (or use the mouse) In Debugger/Monitor ------------------- F1 - Go to the menu F2 - Return to the emulator F3 - Toggle console/debug output/memwatch F4 - Toggle VIA/AY/disk 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> [zc] - 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. Normal breakpoints can use 'z' and/or 'c' modifiers. bs $0c00 <-- Break when the CPU is about to execute code at $0c00 bs $0c00 z <-- Break when the CPU is about to execute code at $0c00 and set cycles counter to 0 bs $0c00 zc <-- Set cycles counter to 0 and continues bs $0c00 c <-- Continues execution (i.e. disabled breakpoint) Main purpose of this modifiers is to make cycle counting easier. If symbols are loaded, they can be used instead of absolute addresses. 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 $0c00 r <-- Break when the CPU is about to read from $0c00 bsm $0c00 rw <-- Break when the CPU is about to access $0c00 bsm $0c00 c <-- Break after then contents of $0c00 change bsm $0c00 rwc <-- Break just before the CPU accesses $0c00, or just after it changes for any reason. International Keyboards under Linux and macOS ============================================= There are lots of problems with some international keyboards under Linux and macOS. The best way to cope with them is to install an UK or US keyboard definition and to switch to it *before* starting oricutron. Under macOS you can do that in the "System Preferences", "Keyboard", "Input sources". Click on the + and search for the UK or US keyboard. Under Ubuntu you can do that in the System menu, select Preferences, and then select Keyboard. In the Keyboard Preferences dialog, select the Layouts tab, and click Add. For a better solution look under "Visual Keyboard" down here. Visual Keyboard =============== Oricutron can display a visual keyboard which also adds a keyboard mapping redefinition feature. It's accessible through a submenu called "Keyboard options". In the submenu you can find: - a toggle that shows/hides the visual keyboard (you can click on the keyboard keys to enter key presses/releases) ; - a toggle that gets you in the key mapping definition mode (you can then click on a visual keyboard key ; press a real key on your keyboard and the mapping will work) ; - a toggle that allows mod keys (ctrl, shift, funct) to be sticky (ie you first click on a key to press it and then either re-click it to release it or click on another key and it will generate a modded key press - e.g. a Ctrl-T instead of T - and then auto release the key) ; - an option to save a keyboard mapping (.kma file) ; - an option to load a keyboard mapping ; - an option that resets the keyboard mapping to the default one. You can also add the following in your oricutron.cfg to autoload a keyboard mapping (here Test.kma in the keymap directory found in Oricutron's directory): ; automatically load a keyboard mapping file autoload_keyboard_mapping = 'keymap/Test.kma' Other options let you display the keyboard and activate sticky mod keys automatically: show_keyboard = yes sticky_mod_keys = yes Serial card (ACIA) emulation ============================ Oricutron can emulate ACIA at address #31C (standard address for Telestrat). The emulation works for Oric, Atmos, Telestrat and Pravetz and can be used together with any disk type. The emulated ACIA communicates with the out-side world trough back-ends. Back-ends can be configured from 'oricutron.cfg' or from command line (see default 'oricutron.cfg' for usage). Back-ends are: - none - disables ACIA support - loopback - every transmitted byte is returned to receive buffer (for testing purposes) - com - Oricutron uses any real or virtual COM port in the host machine and communicates with the hardware attached to this serial port - modem - unites ACIA with attached modem linked to internet with server and client sockets In 'modem' mode are available folowing 'AT' commands: AT - returns 'OK' ATZ - initialize the modem AT&F - initialize the modem ATS0=0 - disable auto answering (close sever socket) ATS0=1 - enable auto answering (open sever socket and start listening on selected port (default is telnet port 23)) ATA - same as 'ATS0=1' ATS0? - returns 'AUTOANSWER OFF' or 'AUTOANSWER ON' depend on current sever socket state ATH0 - disconnect currently connected sockets +++ - if connected switches to command mode ATO - returns from command mode to online ATD ip:port - connects as client to ip:port. 'ip' can be any host name (ex.:localhost) or the real IP (ex.:127.0.0.1) on LAN or in Internet. ATDP and ATDT are alternative for compatibility. CH376 card emulation ==================== Oricutron runs ch376 chip. This chip is able to read a sdcard and a usbkey (and USB port). This chip handles FAT32. usbdrive/ folder is the CH376 emulation folder. It means that when we asked ch376 to read usbkey, it reads in this folder. Please note, that read/write are emulated (see below for emulated ch376 command ). Please note that emulation runs only in telestrat mode. Atmos can run this chip, but the rom had not been release yet (and the card with the rom). Orix (http://orix.oric.org) works with this chip mainly. Don't modify ch376 emulation: contact Jede (email@example.com). Because this emulation is used also in ACE emulator (cpc emulation). Offset and me are trying to keep the same emulation. It's easier to work together than alone. CH376 command emulated : - CH376_CMD_GET_IC_VER - CH376_CMD_CHECK_EXIST - CH376_CMD_SET_USB_MODE - CH376_CMD_GET_STATUS - CH376_CMD_RD_USB_DATA0 - CH376_CMD_WR_REQ_DATA - CH376_CMD_SET_FILE_NAME - CH376_CMD_DISK_MOUNT - CH376_CMD_FILE_OPEN - CH376_CMD_FILE_ENUM_GO - CH376_CMD_FILE_CREATE - CH376_CMD_FILE_ERASE (not emulated under linux) - CH376_CMD_FILE_CLOSE - CH376_CMD_BYTE_LOCATE - CH376_CMD_BYTE_READ - CH376_CMD_BYTE_RD_GO - CH376_CMD_BYTE_WRITE - CH376_CMD_BYTE_WR_GO - CH376_CMD_DISK_QUERY - CH376_CMD_DIR_CREATE (not emulated under linux) - CH376_CMD_DISK_RD_GO Known bug : Under windows, API's file does not send "." and ".." entries when we read the content on the folder. It's a problem because ch376 chip send these entries, when we ask to this chip to read the content of a directory. If someone wants to emulate CH376_CMD_DIR_CREATE and CH376_CMD_FILE_ERASE. It's easy to do : it justs need to copy WIN32 function and replace DeleteFile and CreateDir with rm() and mkdir(). But it's not done because we are not able to test it. CH376 emulation added for : CH376_CMD_FILE_ERASE suppress a file CH376_CMD_DIR_CREATE create folder ROM patch files =============== For detailed usage see included '.pch' files in roms subdirectory. Additionaly unlimited number of binary patches can be added: $XXXX:00112233445566778899AABBCCDDEEFF.... $YYYY:AA55AA55.... $ZZZZ:FF00FF00.... where XXXX,YYYY,ZZZZ - are hex addresses relative to ROM start address (i.e. to set byte at C000 to 00 use: $0000:00)
