I'm releasing ares v119 today, which includes very preliminary Sega 32X
emulation support. Compatibility is currently at around 50% with the dynamic
recompiler, probably closer to 75% with the cached interpreter, and since the
system requirements were a bit too steep (on account of my Mega Drive core being
cycle/dot-accurate), I downclocked the SH2s a bit until I can speed up the
emulator more. You'll currently need about a Ryzen 5 2600 to hit 60fps reliably.
With the underclock, my Ryzen 7 5800X hits 120fps, and without it, 85fps.
Although the compatibility for the new 32X core is a bit low, this is mostly due
to pesky CPU bugs. The accuracy is quite high and I've emulated as much of the
32X and SH7604 peripheral functions as possible. I pass all 161 tests from the
Mars Check Program. It should not take much more work to reach 98% compatibility
in the future. Sega CD 32X emulation support is present, but is likely not
functional, as I haven't tested it yet.
Other major features in this release include Sega SVP support for Virtua Racing,
plus improved Nintendo 64, Mega Drive, and Mega CD emulation compatibility.
I'm going to start working on Sega Saturn emulation now, while Luke Usher works
on Neo Geo emulation. No promises as to when or if these cores will become
playable, I'm just giving you all a heads up since you'll see the skeletons for
these systems in the source code now.

- nall: greatly expanded recompiler/amd64's supported intrinsics
- mia: substantial refactoring around a new virtual filesystem implementation
from nall
SH-2 core finished, started connecting the 32X to it. It executes some
instructions and does some I/O register stuff before hanging. Still gotta
implement the 32X interrupts, PWM, and VDP stuff.
This WIP has the new mia system. It's a pretty massive change ... I hope it will
go okay for you. Feel free to ping me and I'll walk you through it.
Essentially, we want to edit mia/system/neo-geo-(aes|mvs).cpp to load in the
necessary files from MAME's neogeo.zip that is given to it (I have a helper
Pak::read(zipfile, pattern) function to grab files out of the archive for you
into a vector<u8>), do endian conversion, add to the pak, then the Neo Geo core
can see it.
The Neo Geo cartridge support should be enough for Magician Lord and super early
games with no mappers or crypto, so we'll start there and work our way up.
I've started on a Sony PlayStation emulation core with this WIP. The
goal is to work on the MIPS CPU core while I am still well-versed with
the MIPS ISA. The Nintendo 64 core will remain my primary focus,
however.
- PlayStation: implemented initial driver skeleton (no emulation code
yet)
- lucia: added option to group the load menu options into submenus by
manufacturer
- lucia: connected Cocoa-specific application menu options to their
appropriate callbacks
- hiro/Cocoa: fixed compilation issues for HexEdit (the widget is not
implemented, however)
- hiro/Cocoa: fixed a subpixel precision rendering issue causing
blurry fonts [LIJI]
- restructured project layout by moving targets (luna and lucia) out
of ares
- added ares logo to lucia, luna, and mia's about dialog
- lucia: added screenshot capture tool (captures the *next* frame
rendered)
Initial release; fork of **higan** v110.
- the project and core library is now called **ares**
- the simplified user interface is now called **lucia**
- the advanced user interface is now called **luna**
- the game analyzer is now called **mia**
- removed the database editor **genius** from the project
- PC Engine: adjusted rendering viewport for the scanline renderer
from Y=18 to Y=21
