WTF IM PROGRAMMING IN ASSEMBLY!!!!!!!!!!! JUST PLAYED MARIO!!!!!!!!!!!!!!!!!!
제 기준으로는 상당히 갓겜이긴 한데 자바스크립트 ES6와 어셈블리 둘 중 하나라도 시도해보지 않았다면 비추합니다.

一開始會碰到assembly 有點硬 但能了解以前到底是怎麼利用PPU APU CPU(6502 processor) 來做出音效、圖像、規則的。 遊戲裡面有一部份是用JS來檢視header (雖然在那個時候8bits遊戲 並沒有javascript) 但做這個本質上是為了能夠以現代的角度去欣賞以前的人是怎麼製作並運行遊戲的 順帶一題我們是負責製作能夠"模擬"遊戲卡帶的讀取器 並非"製作"遊戲
The assembly explanation alone is worth more than words can say. I just acquired the Supporter Pack. Thank you very much!
It's literally building the emulator by code (with javascript) and it's completely free. And here we get to learn 6502 Assembly too.
I love this game! It is a really good practice game to understand and build your own emulator. Devs made a huge work to integrate tests and validation and, (personally tested) if you have any issue the Discord is really active, answers come in reasonable time, and are always very clear. PLUS: it is a free game for everyone! Only thing: internal debug is really hard to understand, maybe it should be useful to insert some section to practise with the debug tool
