1983年（昭和58年）発売のファミリーコンピュータは、6502 そのものではなく、リコー製のカスタムLSI RP2A03を搭載した。6502 互換のCPUコアから10進演算モードを省き、その代わりに5チャンネルの音源、コントローラー接続、DMAなどを同じチップへ統合した。CPUは約1.79MHzで動くが、画面描画はPPUという専用LSIへ任せる。CPUを豪華にする代わりに、音と絵の専用回路を用意したから、低価格でもゲームを滑らかに動かせた。

A while ago I tried looking for NES vsts since "NES VST" (that one) wasn't good at all.
"RP2A03 VST" is probably the next best thing. It's super limited but sounds way more accurate.

Is there no datasheet for the RP2A03? Or, which 6502 datasheet is the most similar? From what I've seen on various websites, the 6502 itself seems to have few instructions? I want to confirm this properly.

Coming soon to my Bandcamp.
This is an album art featuring my elfsona Spade in the middle and two of my past OC characters I created in 2018 and 2019. The characters on the left and right of Spade are sound chip aliens I came up with in 2018. On the left is Epsilon, a Type-2 Ricohnite. His species is based around on the RP2A03 chip in the NES, and have three different looks based on the pulse widths of the chip (Epsilon's type being the 25% and 75% pulse wave). On the right is Garrett Dane, a Sparcent. His species is based around the sound chip in the SNES (which is often called the SPC700, even though that's the CPU component of the SNES audio system). My old JetStar1997 is on the box. All characters are checking out the CD jewel cases, and there is a light being emitted from the box. This is an album art featuring my elfsona Spade introducing the name of this album. The background is a distorted view of the chiptune tracker Furnace.

これ実機で鳴らすときに顕著なんだけど（誰も気づかないだろと思いつつ自分はめちゃくちゃ気になる）キーオン時のレジスタ初期化ってできないのかな

>ノイズのパターンは、長周期ノイズが32767bit。低周期ノイズは93bit。
RP2A03無印（ボタンが四角い初期型ファミコン時代）では、低周期ノイズが出せない。また、一番低いノイズ音を出そうとしても、一つ上の周波数と同じノイズ音が出てしまう。
ノイズは、キーオンしてもレジスタが初期化されない。そのため、鳴らすたびに音が違う。
低周期ノイズは、長周期ノイズを鳴らすと音が変わってしまう。
