Translating An Old Display To A New One
A defective monochrome STN display on a 1990s Samsung cash register got a replacement using just a Raspberry Pi Pico. Voltage Ventures sampled the display's 4-bit data bus to identify the timing used. The screen is a modest 320 by 240 pixels. The microcontroller then transposes that format into monochrome VGA. Initial work was done with an STM series chip, and later this was moved to the RP2040.

GTA.js, a reimplementation of the 1997 Grand Theft Auto engine in JavaScript and WebGL
Dự án GTA.js tái tạo lại engine của game Grand Theft Auto năm 1997 bằng JavaScript và WebGL, có thể chơi tại gtajs.wtf. Đây là bản reimplement chứ không phải emulator, nên một số vật lý và animation khác với bản gốc, nhưng engine nhiệm vụ chính xác dựa trên tài liệu mtd.doc. Tác giả sử dụng Gemini AI để triển khai hầu hết các tính năng, tham khảo tài liệu mở, ghi chú cộng đồng và trí nhớ cá nhân về game. Hiện tại game đã chơi được nhưng cảnh sát (cops) vẫn chưa được implement.
Lập trình viên nên đọc bài này để khám phá cách tái tạo lại engine game cổ bằng JavaScript và WebGL từ con số không.
