- Source Changes
- --------------
- Changed the system to show a message if coin-lockout is active and
- a coin key is pressed. [couriersud]
- Actually fixed -refreshspeed. [Aaron Giles]
- Reverted previous SCSI CD change which broke some games. [R. Belmont]
- Seibu COP cleanup, primarily sorting the code and identifying
- similarities in different implementations. [David Haywood]
- Fixed an erroneous debug change which leaked into the last version of
- the namcona1 update. [Pierpaolo Prazzoli]
- Fixed marineb colors. [David Haywood, Tomasz Slanina]
- Rewrote INP recording from scratch, since all old INPs are broken
- anyways. Header now includes timestamp, which overrides the default
- time base for MAME's system time. Each frame recorded now gets a
- timestamp. Analog ports are recorded once per frame and interpolated.
- Analog port calculations are all done in fixed point for consistent
- results. A bunch of other minor tweaks in the input port code.
- NOTE: There may still be a few changes to the final INP format.
- [Aaron Giles]
- Improved graphic decoding for Legionnaire, the BK3 tiles are now
- correctly extracted from the TXT region, map screen has correct
- tiles now. [David Haywood]
- Removed CPS1 tile kludges and replaced with per-game ROM mapping
- tables. Ideally, the ROM mapping should be derived from mapping of
- the PALs found on the B board. Note that this is a significant change
- and some new bugs might be caused by it. Unlike previous bugs,
- where extra garbage tiles would appear in the games, the new bugs
- would be tiles or sprites MISSING--so they will be harder to notice.
- This would happen because in some cases the 16x16 regions of the gfx
- ROMs can be used by both scroll2 and sprites, while in other cases
- they must be separated. [Nicola Salmoria]
- PSX updates: [smf]
- - Fixed the SR masks for MTC0.
- - Added ability to test the instruction/data cache ram. The
- scratchpad and BIU register are now handled internally to the CPU.
- - All writes are performed with masks. SWL/SWR used to be implemented
- with two writes ( one byte and one word ) when writing three bytes,
- now it only ever performs one. Byte and Word writes use masks as
- they leave the rest of the register on the bus, which can be
- picked up by larger registers.
- - The read/write functions to use are cached when the SR bits are
- updated, as are the bad address masks.
- - Added coprocessor 1 & 3 support, though they don't do anything
- useful.
- - All loads now go through the delay pipeline, a lwl/lwr will grab
- the value out of the pipeline if it's updating the same register.
- - Added undocumented behaviour of BLEZ/BGTZ. The comparison for zero
- can be changed by specifying an alternate register in the RT field
- ( the documentation says you should always use register 0 ).
- - Restricted to 16 COP0 registers & generate an exception if any of
- the 5 for the MMU are used.
- - Added BCF/BCT instructions, although I have found no conditions
- that affect them yet.
- - Generates an exception if any MMU instructions are executed.
- - Sets the CE instruction for all exceptions, not just those
- involving a coprocessor. The bits of the opcode that specify the
- coprocessor are grabbed no matter what the instruction.
- - Added TAR register and BT bit in SR. When an exception occurs
- during a branch, BT determines whether it was taken or not. The
- TAR register gets set to the destination of the branch.
- - Fixed the BD bit when you are in a branch delay slot and you didn't
- take the branch, this shows up in the pipeline as !pc.
- - Fixed branches within a branch delay slot.
- - Multiply & divide instructions can be aborted if you write to
- HI/LO before reading the result. Added data breakpoints, you
- don't appear to be able to set breakpoints on any of the
- addresses internal to the CPU.
- - Multiply/divide/GTE instructions can execute when an exception is
- taken, although the EPC indicates that it hasn't. The BIOS avoids
- rerunning GTE instructions as they are destructive, so you have to
- make sure they run.
- - Added bus error handling, PSXCPU is limited to 8mb of ram & any
- access outside this range will trigger an exception. I believe
- this is to be an internal limit.
- - Added CXD8611R as a specific CPU type, System 12 appears to allow
- more than 8mb of ram & it's possible that this is different.
- - Mapped out all instructions to either generate an exception or
- ignore bits.
- - Updated the disassembler to match the decoding.
- - Fixed disassembling of branch instructions in a branch delay slot.
- - Lui checks for a ori/addiu following and will show you the result.
- - Added step over/out support.
- - Fixed standalone disassembler.
- - Fixed SZ0 truncation.
- - Fixed IRGB truncation and conversion to IR1/IR2/IR3
- - Added IR1/IR2/IR3 saturation when calculating ORGB.
- - Fixed OTZ sign extension
- - Fixed reading from SXYP
- - Fixed reading from IRGB
- - Fixed writing to LZCR
- - Fixed sign extension of GTE control registers
- - Fixed writing to FLAG
- - Fixed flag calculation in F macro.
- - Fixed avsz3 & avsz4 flag & otz calculation.
- Fixed unicode crashing bug with input names. [Aaron Giles]
- Renamed input port functions: [Aaron Giles]
- readinputport -> input_port_read_indexed
- readinputportbytag -> input_port_read
- readinputportbytag_safe -> input_port_read_safe
- Added machine parameter to input port functions. Updated
- many drivers to accomplish this.
- Bulk converted drivers explicitly calling input_port_n_r() with a
- bogus offset to calling input_port_read_indexed() instead.
- [Aaron Giles]
- Memory map merges for drivers starting with U, V, W, and Z.
- [Andrew Gardner]
- Mostly fixed sound in N64-based games. [Adam Gashlin]
- Correct DMA functionality in N64-based games. [Ville Linde]
- Aerfboot improvements: [robiza]
- - sprite offset are now correct
- - split spriteram in two parts
- - identified last sprite for the two parts
- - promoted to "working" (no sound)
- Pallavol improvements: [robiza]
- - fix for sprite's y-coordinate
- - implement lookup table for convert sprite code in the real code
- - change the name to "1991 Spikes (Italian bootleg)
- - fix scroll
- - fix offset
- Merged sonson memory maps. [Nicola Salmoria]
- Added mising TC0060DCA sound mixer to the Taito Z driver. Marked one
- dblaxle ROM as BAD_DUMP. [Nicola Salmoria]
- Changed the 8237dma implementation into a device. [Wilbert Pol]
- Fixed wrong tile-sprite priority in m62 driver. [robiza]
- Fixed nec v30 dasm when a "real-time encrypted cpu" is used. Also
- fixed Execution Clocks for add,addc,and,or,xor,cmp,sub,subc
- instructions. [robiza]
- Removed the hardcoded dependency on a 8254 device from the 8042kbdc
- code. Changed the drivers using the 8042kdbc to define their own
- 8042kdbc - 8254 dependency. [Wilbert Pol]
- Rewrote core memory handlers as inline functions. These should be
- easier to trace through in a debug build, yet should operate the same
- as before. [Aaron Giles]
- Created a complete set of functions for all databus sizes (8,16,32,64)
- and all endiannesses. A few functions are redundant, but it is now
- very clear which functions to use in which scenarios. It is also now
- possible to rely on being able to access values of 8, 16, 32 or 64
- bits via the built-in accessors without fear of crashing.
- [Aaron Giles]
- Updated all cores using 8-bit handlers to explicitly call the 8-bit
- handlers with the appropriate endianness. [Aaron Giles]
- Fixed a few games which were calling n-bit handlers directly to use
- the generic forms. In the future, this is all the access drivers will
- have. [Aaron Giles]
- More opcodes fixed in gussun oyoyo and risky challenge. [robiza]
- Added tags and locations to dips for marvins.c and matmania.c.
- [Fabio Priuli]
- Enabled roz tilemap in emeraldia, but it's not centered in the right
- position when it's not in its original dimension. [Pierpaolo Prazzoli]
- Fixed 'lghost*' Dip Switches. [stephh]
- Reduced the number of save state callback types from 3 to 1. The
- only remaining form is the one that takes a pointer parameter. Added
- macros for STATE_PRESAVE and STATE_POSTLOAD to define common
- functions. Added machine parameter to these functions. Updated all
- drivers and CPU/sound cores to use the new macros and consolidate
- on the single function type. As a result pushed the machine parameter
- through a few initialization stacks. [Aaron Giles]
- Removed unnecessary postload callbacks which only marked all tiles
- dirty, since this is done automatically by the tilemap engine.
- [Aaron Giles]
- Updates for the driver wc90b.c: [ClawGrip]
- - Removed the second YM2203, it isn't present on the bootleg boards
- - Changed the clocks according to the oscilators found on the board
- Added the running_machine* parameter to the function passed into
- cpunum_set_irq_callback() and adds the IRQ_CALLBACK macro for
- the callback function. [Oliver Stoenberg]
- Cleaned up the Machine usage in the osd/windows files and added the
- running_machine parameter where possible. [Oliver Stoenberg]
- Various tweaks/fixes from MAMEPlus:
- * save state support for FD1094 chips
- * improved graphics in athena
- * improved sound balance in armedf
- * derived refresh rate for toaplan1 games
- * improved sound balance in tmnt games
- * derived clocks for suprridr
- * tweaked xmen visible area
- * derived clocks and refresh rate in twin16 driver
- CPS1: Verified some gfx ROM mapping tables against PAL dumps. Improved
- understanding and emulation of palette related registers.
