That's exactly what I was analyzing. They go viral very quickly, and there's no way to verify if they contain viruses or steal information.

It seems a bit crazy to me, plus now it opens the door to many iPhone copies... we'll have to be very careful

Really cool project! The only thing I noticed is that the performance feels a bit slow at times, and it could use a little more fluidity, especially when interacting with the model.

Other than that, everything feels really well done. Building something like this in JavaScript/HTML, especially with a 3D model this detailed, must be quite challenging from an optimization standpoint.

Great work!

I spent the last few months porting the original PlayStation Metal Gear Solid (1998) decompilation directly to an ESP32-S3 microcontroller, targeting the Seeed XIAO ESP32-S3 Sense and Waveshare handhelds.

AI was used to port to ESP32, and human talent was used to assemble the circuit, hardware, and proprietary knowledge of ESP32 and FreeRTOS optimizations.

Rather than running an emulator, the decompiled C source from mgs_reversing is compiled natively to Xtensa machine code. Everything the original PS1 hardware provided, including the GTE, GPU, BIOS scheduler, and CD drive, is reimplemented in software on top of ESP-IDF and FreeRTOS.

SoC: ESP32-S3, dual-core Xtensa LX7 @ 240 MHz, 512 KB internal SRAM, 8 MB Octal PSRAM.

Display: 320×240 LCD (ST7789 / ILI9341) over SPI at 40 MHz.

Storage: MicroSD card over SPI containing the full game stage assets (STAGE.DIR).

Internal SRAM is fast but limited, while PSRAM provides 8 MB of additional memory but sits behind the same cache subsystem used for external Flash.

Placing FreeRTOS task stacks in PSRAM initially appeared to work, until a task performed file I/O such as fopen().

When external Flash cache was disabled during Flash/PSRAM access, the CPU could no longer safely access task stacks stored in PSRAM, causing an immediate SoC crash.

That's incredible, I never imagined that was possible. The Apple ecosystem is very closed.I was checking if it exists for the iPod Classic since it's my favorite
