CHIPnGo VS MicrocodeDecryptor

CHIPnGo A custom-built CHIP-8 hand-held gaming console powered by a STM32 microcontroller.

It's essentially complete now (other than some planned firmware tweaks) and you can check out the source code on GitHub. You can also see a video if it in action here.

I ask because I recently made a console for CHIP-8 which is an old 8-bit “fantasy console” by writing a CHIP-8 emulator for a STM32 MCU. So games still have that 8-bit limitation like you’re going for but the STM32 has a bit more power than actual 8-bit MCUs which is useful for working with the display and stuff.

Now that I have a nearly complete prototype for my CHIP-8 game console that I've been working on, I wanted to attempt to create a custom PCB to truly make it portable.

A couple months ago, I decided I wanted to learn more about embedded software development so I thought it would be cool to port my emulator to a STM32 MCU and try to build a handheld game console since CHIP-8 never existed as an actual standalone physical machine. I have a working prototype and the firmware (which I wrote from scratch so it took quite awhile to get right) is basically done (though I will likely do some refactoring and add a bit more robustness) which can be found here. Next step is to design a PCB and add battery power to have a no-shit portable game console.

Microcode decryptor A team of researchers has released a tool to decrypt and unpack the microcode for some low-power Intel CPUs. This makes possible to understand how Intel has implemented various security fixes and features. Among the security fixes you can find the one about the famous Spectre vulnerability. Among the features you can dig into the implementation of Intel TXT, SGX or VT-x.
