in the mizar lib. This is suboptimal, but the code seems to
crossreference across object files and from the bus code into the driver
code.
At least the source now links again. (nw)
- Allow stringing multiple callbacks together recursively. Chained callbacks will be read or written in sequence, and each can be configured with its own type and mask/shift/XOR parameters.
- Chained input callbacks cannot have overlapping masks (there's no such thing as a free multiplex). Chained output callbacks have no such restriction.
- Remove the constant parameter for the LOGGER callback type: it makes no sense for output, was always zero in existing usage, and is now unnecessary with callback chaining.
- Change LOGGER behavior for writes to log the user-defined message only if the output as masked is nonzero. With callback chaining, this can be used to monitor when individual bits become active.
- Constant read callbacks can no longer have MCFG_DEVCB_XOR or MCFG_DEVCB_INVERT specified (makes no sense in this context).
- Add a MEMBANK callback type to allow output bits to be used for bank-switching.
- Add ASSERTLINE and CLEARLINE callback types that raise or lower an interrupt line if the selected bit of the written value is active. These are intended for where periodic or ready-pulse signals from devices are used to trigger IRQs that the CPU program will independently acknowledge.
- Add MCFG_DEVCB_BIT as shorthand for masking and shifting out an individual bit for a callback.
- Removed DEVCB_LINE_DISPATCH_<n>. Where we're going, we don't need line dispatcher devices.
The incompatibility of compilers with regard to post-C90 printf string formats is shockingly bad. There seems to be no easy way to format a 64-bit value and please both gcc and clang, let alone MSVC.
-netlist: Added new devices: [Ryan Holtz]
* Intel 2102A 1Kbit (1024 x 1) Static RAM
* 74365 Hex Bus Driver with 3-State Outputs
* Generic 2- and 3-terminal Tristate device
* Note: Tristate device and 74365 do not actually tristate, they are simply a way of combining multiple outputs + chip enables.
selmenu: use LRU cache so icons don't all need to be reloaded on scroll
uismall.bdf: set default character for missing glyphs
rendfont.cpp:
* encapsulate many BDF and BDC handling details
* make file I/O 64-bit clean, check for allocation errors
* more solid BDF parser with error messages and trace logging
* fix heap smash when building bitmaps for BDF fonts
* extend BDC format to support high planes and default character
* render default character if glyph not found for BDF/BDC
- Uses the standard 6840 PTM core for sound generation
- New MM583 Noise Generator device
- New DAC-76 DAC sound
- Use resistor network values for colors
- Use bankdev device for banking
Use standard uint64_t, uint32_t, uint16_t or uint8_t instead of UINT64, UINT32, UINT16 or UINT8
also use standard int64_t, int32_t, int16_t or int8_t instead of INT64, INT32, INT16 or INT8
ataxx: Fixed missing sound channel caused by one dac not being hooked up and one dac being hooked up to two addresses.
bestbest: Fixed high pitch screech caused by incorrect addressing (two dacs weren't hooked up and two were hooked up to two addresses).
cchasm: Fixed static noise generation caused by feeding the same bit to both dacs.
cheekyms: Slightly improved sound by implementing sound triggers as 8 x 1 bit dacs instead of 1 x 8 bit dac.
galeb: Fixed sound by implementing it according to http://www.deltasoft.com.hr/retro/galebemu.htm & implemented enough of LOAD/SAVE to stop it hanging.
hard drivin: (all games in driver) Improved 12 bit controls, although centre still goes out of sync.
mea8000: Converted to a sound device.
megaphx: Fixed noisy samples due to wrong format.
microvsn: Fixed sound pitch caused by incorrect usage of write_signed8().
seicross: Changed to a 4 bit dac as samples are packed nibble.
spaceg: Preliminary sound using space invaders samples.
suna8: Changed to a 4 bit dac as samples are packed nibble.
vcombat: Fixed static during machine gun fire due to incorrect dc offset removal.
vectrex: Fixed noisy samples due to wrong format.
wheelfir: Fixed sound, eeprom & analogue steering wheel and brake pedal.
Turbosub had a ROM_COPY declaration with an expression ('ROM_COPY( "main_code", 0x18000 + 0x2000,...) and this simply did not work with the new model. This required changing ROM_* declarations to more resemble how they used to be and to perform the conversion on load.
This is a redo of the split first submitted in #137, with the following differences:
* The newly refactored rom_entry data structure is used
* I've kept the refactored softlist code in src/emu, in order to defer the mechanical process of moving it
* I've kept includes of softlist[_dev].h out of diimage.h, so that changes to either do not trigger an emu.h recompilation
* Obviously, this goes against the latest master
* Mark lots of things constexpr in attotime and turn macros into functions
* Add base classes for HLE matrix keyboard and buffered RS232 device
* Make generic keyboard/terminal more usable
* Keyboard has configurable typematic delay/rate
* Keyboard has selectable JIS/ANSI layout
* Keyboard handles simultaneous keypresses more intuitively
* Keyboard uses meta to set high bit
* Terminal has configurable auto LF on CR, auto CR on LF and local echo
* Terminal has audible bell
* Untangle Olivetti M20 keyboard from generic_keyboard
* Add notes to Olivetti M20 keyboard emulation
* Make Olivetti M20 keyboard match physical layout
* Untangle RM Nimbus keyboard from generic_keyboard
* Fix natural keyboard mode with RM Nimbus
* Untangle x68k keyboard from generic_keyboard
* Improve x68k key names and mapping
* Improve x68k typematic behaviour
* Untangle QX-10 keyboard from generic_keyboard
* Keep NGEN keyboard barely working
The keyboard should communicate at 1,200 Baud, but due to bugs in the SCC
it's set to 9,600 Baud. The sun4c machines program the Baud rate
generator dividers for the serial ports with 00:0e and the dividers for
the keyboard/mouse ports with 00:7e. Therefore the ratio of Baud rates
should be (0x7e + 2) / (0x0e + 2) = 128 / 16 = 8. However both the RS232
ports and the keyboard/mouse ports run at 9,600 Baud, when the
keyboard/mouse ports should run at 1,200 Baud (which is 1/8 of 9,600 which
matches the ratio of the divider values).
I've artificially limited the rate the keyboard can transmit at to be no
faster than it could at 1,200 Baud using a timer. I can remove this hack
once we get correct SCC divider behaviour.
I attempted to hook up the SCC interrupts to level 12 as specified in the
SPARCstation-1 Programmer's Model in the table on Page 19. No interrupts
seem to be generated, so either I've screwed this up somehow, the Sun
isn't enabling interrupts, or there's another bug in the SCC emulation.
Sorry if I've screwed it up - I won't be offended if someone replaces it
wholesale.
The keyboard receives the reset commands from the Sun and sends back the
self test pass response, but the SCC seems to get a buffer overrun error.
So it appears that the received data isn't being read out. I haven't been
able to work out why.
* .h -> .ipp for things that aren't really headers
* make more stuff in selmenu private
* move the remembered driver/software associated with the snap to the cache object
* start cleaning up constness in datfile manager - it's still a mess of non-const statics
