Systems promoted to working
---------------------------
Paracaidista [Roberto Fresca, Grull Osgo]
* sound/c6280.cpp: Improved accuracy of volume control and LFO.
* video/huc6260.cpp: Suppress side effects for debugger reads, fixed save state issues.
* video/huc6270.cpp: Suppress side effects for debugger reads.
* Chose better types for member variables, made more local variables const, reformatted code.
* Corrected the calculation of the voice DC-block HPF.
* Audio streams are in voltages.
* Cross-checked component values with parts list, and corrected a couple of them.
* Also updating master volume and pitch adjustments on reset.
* There are no byte enable or write strobe signals for I/O, and there's
only a single operand size, so word addresses make more sense.
* Also changed STBS/STWS to allow any valid signed or unsigned value of
the applicable size. This allows vamphalf attract mode to work as
well as the storage test.
-misc/limenko.cpp: Better input types for spotty.
* Only a single I/O access is generated for an I/O word read/write. The
upper half just disappears if the pins aren't present. This fixes
"phantom" I/O accesses, allowing address maps to be cleaned up a bit.
* Reduced I/O address width for models with 16-bit external bus to match
hardware.
* Made addressing consistent between interpreter and recompiler for I/O
double-word accesses.
* Implemented power down via internal I/O write for E1-X and later
cores (none of the games I tested actually use it).
-misc/pasha2.cpp: Enabled the recompiler for Zooty Drum - it gets just
as far as the interpreter now.
* Got package option (T, N or B suffix) out of device type.
* Enabled 4x PLL clock multiplier for GMS30C2216/GMS30C2232.
* Implemented entering power down mode via MCR for E1 and E1-X cores.
* Marginally better code generation for a few instructions.
* Log available bus/memory configuration options for different cores.
* Added post load handler for E1-XS and E1-XSR cores to install SDRAM
mode/configuration handlers if necessary.
* Improved comment about different Hynix and Hyperstone CPU models.
-cpu/drcbearm64.cpp: Don't update flags that aren't requested in a few
places.
------------------------------
Happy Planet [Guru]
New working clones
------------------
Mahjong Electron Base (parts 2 & 3, Japan set 3) [little0]
- excellent/es8906.cpp: fleshed out a bit
* Assume ROL sets the V and C flags the same way as SHL and MOVI clears
the V flag.
-cpu/drcbex64.cpp: Optimise SUB x,0,y to a NEG instruction (gets down to
one instruction from two or three a lot of the time). This had been a
TODO comment for ages.
-cpu/drcbex86.cpp: Got rid of unnecessary std::function use. This
substantially reduces the code size and reduces allocations during code
generation.
-cpu/drcbearm64.cpp, cpu/drcbex64.cpp, cpu/drcbex86.cpp: Got rid of the
intermediate tables in favour of bit switch statements. This improves
startup time, reduces code size, and gives the compiler more
optimisation opportunities.
-cpu/drcbearm64.cpp, cpu/drcbex64.cpp, cpu/drcbex86.cpp: Got rid of
asmjit namespace qualifiers left over from when the class declarations
were in headers and hence outside the scope of the using namespace
statements.
------------------------------
Petit Lot (ver. 4.1) [buffi]
New clones marked not working
-----------------------------
Ichi Ban Jyan (Ver 2.35) [buffi]
- misc/fresh.cpp: small cleanups
- skeleton/cle68k.cpp: added 2nd RAMDAC place-holder
---------------------
Street Fighter III 3rd Strike: Fight for the Future (Asia 990512, NO CD) [Goldenglober]
Street Fighter III 3rd Strike: Fight for the Future (Asia 990608, NO CD) [Goldenglober]
- dynax/ddenlovr: myunivbl and myunivbl2 aren't bootlegs after all, so rearrange accordingly
- igs/igs011.cpp: demoted xymga to not working as it hangs during attract
* Fixed behaviour of delayed branches, trace exceptions, and saved PC
calculation for error exceptions in delay slots for the interpreter.
All instructions in delay slots, branching instructions that can raise
exceptions and tracing shoud now (mis)behave properly for the
interpreter, including things the manual says you shouldn't do.
* Fixed and optimised flag updates for left shifts for the recompiler.
* Optimised ROL instruction for the recompiler and made flag calculation
equivalent to the interpreter both with and without the "Missioncraft
flags" compile-time option.
* Only block interrupts for one instruction following a delayed branch.
* Optimised the SOFTWARE instruction a little for the recompiler.
* Added more SDRAM configuration logging and cleaned up code a bit.
-cpu/drcbearm64.cpp: Apply the change from 7efe37938f to OR and
XOR instructions as well, and fix some cases where a 32-bit logical
operation would fail to clear the upper bits of a register.
-cpu/drcbex64.cpp: Avoid more conditional branches on conditional MOV.
