From the project
Famicom cartridge built around one RP2350B (Waveshare Core2350B): PRG/CHR emulation, NSF player, PC-to-Famicom screen streaming. KiCad 10.
Waveshare Core2350B(RP2350B)1枚で作るファミコン用カセット。
- PRG・CHR を RP2350B がリアルタイムにエミュレート(マジコン。NROM/CNROM/UNROM/MMC1/MMC3 などをファームで実装) - NSF 再生(バンク切り替え・WRAM 対応。拡張音源は PWM で46番に混ぜる) - PC→FC 画面転送(PPU の読み出しに直接応答する FC-PICO 方式)
- 基板 rev0.2 の設計が完了(2層、DRC エラー0・未接続0)。未発注・未実装。 - ファームウェア: 動作確認用の bustest(CPU バスでテスト ROM を返して音を鳴らす)と chrtest(PPU に CHR を返して画面に格子模様を出す)、 マジコン本体の magicon(.nes を動かす。NROM/MMC1/UxROM/CNROM/MMC3/AxROM、PRG + CHR 384KB まで)を作成、ビルド済み。未実機。firmware/ - rev0.1 からの変更: USB の予備ランド(J6)、拡張音源の音量用の半固定抵抗 VR1(KOA KVSF637AC104)を追加、 電源・音声の配線を太くした(+5V 0.8mm、VBUS 0.6mm、GND 0.5mm、+3V3 0.4mm、音声 0.4mm)、J5 の 12〜14番を…
