This hack is there for quite a long time, and lots of games crashes if it's disabled.
But it's still a hack, so it shouldn't be enabled hard coded. This commit create a new
ini option for this hack which is enabled by default.
Maybe some games does still run very fine without this hack.
This is a one instruction optimization for integer loadstores.
Makes sure to enable nop padding in some cases where a fault can still happen and cause us to overwrite other instructions that aren't meant to be.
Align our dispatcher to a page so we can jump to it with a ADRP+BR pair instead of ADRP+ADD+BR.
Also make sure to save /all/ of our callee saved registers that we are supposed to save.
Requires PR #1705 prior to merging.
Adds the ability to flush the cache and maintain state.
Adds the BindToRegister ability.
Sorts register usage as callee saved used first, reduces dumping pressure when jumping to external routines/interpreter.
Adds a function to store a register, for use when flushing a register that won't be used during the rest of a block.
Unfortunately the map files in American Mensa Academy don't correspond to the release version.
But at least now if other games use those map files we will be able to load them.
Fixes#7917
The first memset was clearing the delicate bits of the std::string
in the struct, causing segfaults.
I also removed the rest of the memsets because they were paranoid,
unneeded and waseful. We shouldn't be managing the ssl libraries
structs for it.
I checked and the ssl library's functions were already memsetting
those structs as needed.
Even in games that require MMU mode, loads outside the area specified by
the BAT are rare, so fastmem is a substantial improvement.
All of the interesting changes are in the backpatch handler, to make it
generate DSI exceptions correctly.
Previously the two operand register selection bits were inverted, causing "CMPAR AC1, AX0.H" to be disassembled as "CMPAR AC0, AX1.H".
DSP RE is always fun: on the one hand Nintendo does a lot of stupid shit, so anything weird could be a legitimate bug of the UCode that is not supposed to make any sense. On the other hand, Dolphin *also* does a lot of stupid shit, so there's always that doubt.
Note: completely untested change - done with the GH text editor, just to show you how much I care :) . These operand descriptions are only used for disassembly, so no real behavior change is expected.
The libusb driver must be installed on the adapter (e.g. zadig can be used to install the driver in Windows). GameCube pad controllers are supported and will override the current input device assigned to the port. GameCube controller buttons are auto-configured and cannot be re-assigned. Rumble is supported. Hotplug is supported while playing a game. If a controller is unplugged from the adapter, Dolphin will fallback to using the host input device on that port. If a port on the adapter is unused, Dolphin will use the host input device for that port, allowing a mixture of host input devices and controllers connected to the adapter.
The adapter support can be disabled in the Controllers config if the OS driver is preferred (allowing the pad buttons to be reconfigured).
One adapter per system is supported.
