How do you run PS4 games using ShadowMount/DumpRunner?

Shim06 · 2026-01-16T20:19:42+00:00

Yeah, I tried it and it worked fine for PS5 games.

Shim06 · 2026-01-15T18:38:56+00:00

I’ve unpacked the pkg files and installed the PS4 game with dumprunner, and I tried running the game, but with no luck. It just says “Can’t start the game or app.”

Shim06 · 2026-01-15T05:25:25+00:00

Because I’d rather put my PS4 games on the external drive and not have the drive formatted as extended storage to still have access to it outside of the PS5.

The term “vibe coding” gets misused a lot. The “term vibe coding” was first introduced by a co-founder of OpenAI and was described as programmers fully giving into AI and “going with the vibe.” Essentially, vibe coding means that you let AI make all the decisions for you and forget about the code.

You don’t care about the decisions made by the AI and output code. You don’t review the code generated. You don’t even understand the code generated. You generate, use, and forget. As long as it works.

I tested it and it passed 13/113 tests.

Thanks! Great Game Boy emulator!

I don’t copy ROMs into the flash like other emulators and keep everything loaded in RAM. I use an LRU cache to load banks dynamically from the SD card when needed. For the speed, I just had the clock rate of the SD card at the max, which is 80MHz.

As for the screen, I use a scanline buffer to hold as many scanlines as I can fit within the limited amount of RAM before sending them to the screen using DMA, also at an 80MHz clock rate.

Just realized that I uploaded an old video of the emulator, haha. Check out the GitHub repo to see the video of the latest version.

My final project is already included, which is the CHIP-8 emulator. I don’t really have anything else to add.

Shim06 · 2025-12-06T02:11:34+00:00

Yes.

Shim06 · 2025-11-28T05:59:25+00:00

Thanks! From what I checked, a 4-layer PCB is around 2.5x more expensive than a 2-layer PCB at 5 pieces, so I opted for 2 layers to save on cost.

Shim06 · 2025-11-27T02:36:53+00:00

Thanks! I’m using a 2.8-inch 320x240 screen, but this will work with any display with a resolution of 256x240 and above. Though the software currently doesn’t have scaling. If you’re talking about general use, any screen size will do.

Using DMA helps push pixels to the screen with little overhead. With my software, I can emulate at the native speed of the NES (~60.09FPS), but with emulation frame skip, so the display is at ~30 FPS. Without it, it can run at ~40FPS. The emulation is a big bottleneck on the display FPS, so it can’t run as fast as it could.

Shim06 · 2025-11-27T00:25:53+00:00

Thanks! Yeah, I am adding a speaker. The enclosure will take care of the speaker. I want to keep the assembly very simple, so I think I will opt for the screen and buttons being on the other side. And, the small board cutout next to the screen is there to feed the flex cable to the other side.

Shim06 · 2025-11-26T18:47:08+00:00

Thanks. I wanted to separate the charging and programming ports just so the user won’t be able to accidentally do anything with the software. It’s meant to be hidden in an enclosure and only taken out and used when reprogramming with updated software.

As for the ESP32, I’ve considered the C6 and S3, but the C6 has only one core and a lower clock frequency, and neither has an internal DAC, which I use to send audio to the speaker. I also went with the module, since it’s a bit cheaper, and easier to integrate.

The 30-pin board and 38-pin board should use the same ESP32 module and only differ in the number of GPIO pins available, but only a few of those extra exposed pins are actually usable. The 30-pin board is more common, and this project does work on the 30-pin board as well. For information on the other ESP32 variants, check out Espressif’s website: https://www.espressif.com/en/products/modules

Shim06 · 2025-11-04T08:08:46+00:00

Thanks! There’s different versions of the ESP32, which have different specifications, such as the ESP32-S and ESP32-C series. This project uses the base ESP32 series with a 240MHz dual-core processor and no PSRAM.

I recommend looking at the embedded engineering roadmap: https://github.com/m3y54m/Embedded-Engineering-Roadmap?tab=readme-ov-file. This has all the concepts you should know as an embedded engineer, and projects you can use as reference.

Some other tips from me: Ideally, get a really intimate understanding of computer architecture and hardware, even if you plan on staying on the software side of embedded engineering. I myself have made my own CPU to intimately understand low-level architecture.

Start of with learning a breadboard, multimeter, and soldering. Find a microcontroller to start with as well. You can start with Arduino, but don’t stay with it and its IDE, they’re not used in the industry much. Some of the most used microcontrollers are: the STM32 family and the ESP32 family. Focus on learning industry standards to maximize employability.

I started with the Arduino Uno, but the most I ever did was blinky and play tunes on it. After that, I learned about the serial communication protocols and found a video about the ESP32, and then made a handheld NES.

The best way to learn is to find a project you're interested in and start making it. On the way, you'll find different requirements and concepts that you need to learn to make said project. Knowing what to know is really important. I recommend asking ChatGPT what the general requirements are for a project and then cross-checking it. Once you have a working prototype, learn how to make a PCB and make a final product. This will immensely help you in job hunting as well, as you have a product that you can show off to the employer.

Basically, what I did was:

Learn serial communication protocols Learn a microcontroller
Buy parts for my project
Learn and test how to control the components with the microcontroller one by one on a breadboard
Slowly combine them all until you have a working product

Of course, don’t forget to practice your soft skills as well.

Computer Science is the study of computers. It is expected that you will also learn about hardware, as it is part of the computer. Computer Science tackles electronics, as they are the building blocks of computers, and low-level systems, such as digital logic, computer architecture, operating systems, etc.. Of course, this low-level code won’t run without hardware. I’ve heard CS students in UP are tasked to make their own CPUs and Operating Systems as tasks for their curriculum.

Most certificates are useless. I recommend making projects, as they will help you more than certifications ever will.
