FEX-Emu: Fast(-er) x86 emulation for AArch64

How we're creating a better gaming experience on ARM

<p>QEmu is a great project but it isn't really designed around high performance gaming. Let's create a new project that is specifically designed for running x86 and x86-64 games on AArch64. With FEX-Emu now off the ground let's talk about the problems of translating x86 and x86-64 to AArch64. Translating 32-bit games to a 64-bit process encounter a bunch of fun issues. On top of that, translating x86/x64 to Arm has issues that you wouldn't really expect. Come along for the ride with all the problems we encountered and where our future plans lie with FEX-Emu.</p>

<p>ScummVM reached a milestone with the release of 2.5.0. Version 0.0.1 was released 20 years ago. The latest release was also the first release that included support for a few Director games.</p> <p>MacroMedia Director, later Adobe Director, was a multimedia application authoring platform. Its ease of use led to a huge number of graphic adventure games being written with it. This was the late 90's. Some well known games are the Journeyman Project, Total Distortion and Spaceship Warlock.</p> ...

<p>While writing a Z80 emulator, you might ask yourself: should it be 100% accurate ? Maybe not, if you just want to run old software. But what if you're not and this old software accidentally depends on undocumented behavior ? In this talk we'll explore how, 30 years after its design, a few people on a Russian retro-computing forum reverse engineered an undocumented Z80 register: MEMPTR. And how 6 years later, another even less known secret register was discovered.</p>

<p>Emulators, especially ones targeting real time performance, can become very complex, and can present unique debugging challenges - more akin to cpu, operating system and compilers than typical software projects.</p> <p>In this talk I will cover common and not-so-common classes of bugs that manifest themselves in a vast range of emulators (gameboy, dreamcast, x86/64 usermode will be used as examples), and strategies and heuristics I've used over the years to identify, prevent, mitigate, fix ...

<p>The PlayStation 3 features one of the most ambitious and fascinating architectures among video game consoles. Once deemed near-impossible to emulate in real-time, we now celebrate the 10th anniversary of its most popular emulator: RPCS3, a free and open-source software capable of running two thirds of the console's catalogue on PC.</p> <p>This talk describes the hardware and software stack of the PlayStation 3, covering the IBM Cell/B.E. CPU, Nvidia RSX GPU and Sony's CellOS operating system ...

<p>Most emulator authors will have encountered a test suite; a series of compliance tests that indicate whether their implementation matches original hardware. But these suites tend to assume a lot of working functionality beyond the part they are specifically testing, often being designed by an intelligent human being to test finished emulators.</p> <p>This presentation covers an alternative source and target of tests: random numbers, to test individual processor instructions, so that future ...

<p>SquirrelJME is a from-scratch and clean-room built Java Virtual Machine implementation which targets the J2ME/Java ME runtimes which have been historically used for mobile applications such as those running on flip phones. The presentation will go over the unique challenges of implementing a JVM along with differences compared to traditional CPUs. Additionally due to the rapidly changing nature of traditional desktop Java Virtual Machines, backwards compatibility with older byte codes is not ...

<p>A disadvantage of many emulators is that they require the user to know how they should configure a machine — which model, which expansions and peripherals — and what they need to type before they can use their desired classic software. Wouldn't it be nice if the emulator could just figure all that stuff out for you?</p> <p>This presentation covers three means of doing so: ahead-of-time static analysis, runtime dynamic analysis, and brute-force try-them-all parallel execution.</p>
