When the original author open-sourced the project, I obtained the original design through a trusted source (not reverse engineering). Upon reviewing the schematics, I identified several defects in the audio circuit design of the original Makoto — so I designed my own improved version from scratch.\u003c\/p\u003e\u003cp\u003eThe audio circuit of the RE2-YM2608 MSX card is \u003cstrong\u003ecompletely original\u003c\/strong\u003e, designed independently without plagiarizing any other project. The logic circuit correctness was verified using a Makoto-to-RE2-YM2608 conversion board before committing to the final single-board design.\u003c\/p\u003e\u003ch2\u003eWhat Makes It Special?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eImproved audio circuit:\u003c\/strong\u003e Fully redesigned by Denjhang, addressing defects found in the original Makoto design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull ADPCM support:\u003c\/strong\u003e Verified to play tracks with ADPCM samples completely normally\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYM2612 + SN76489 compatibility:\u003c\/strong\u003e Can play Mega Drive \/ Genesis VGM tracks via vgmplay's conversion function\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMSX cartridge form factor:\u003c\/strong\u003e Plugs directly into your MSX cartridge slot\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOriginal design:\u003c\/strong\u003e Audio circuit independently designed, not derived from any other project\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen source heritage:\u003c\/strong\u003e Based on the open-sourced Makoto project with significant improvements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eAbout the YM2608 Chip\u003c\/h2\u003e\u003cp\u003eThe \u003cstrong\u003eYM2608 (OPNA)\u003c\/strong\u003e is Yamaha's most powerful PC sound chip of its era, combining \u003cstrong\u003e6 channels of 4-operator FM synthesis\u003c\/strong\u003e, a \u003cstrong\u003e3-channel SSG (PSG)\u003c\/strong\u003e section, a \u003cstrong\u003erhythm sound generator\u003c\/strong\u003e with built-in samples, and a full \u003cstrong\u003eADPCM channel\u003c\/strong\u003e for high-quality sample playback.
