くらむぼんのホームページ ←RPGツクールMV用のプラグインや音楽素材・ゲームを置いてます。
ドット絵をアップスケールするやつ ←「なめらかに拡大」のスクリプト（xBR法）をお借りしました。ありがとうございます！
RPGツクール2000→MV素材変換器
- 下部の設定を調節（基本的にそのままでOK。「拡大方式」は好みで決めてください）
- 「変換する画像を選択」を押してRPGツクール2000のキャラチップor顔グラフィックorマップチップを選択（直接ドラッグ＆ドロップしてもＯＫ）
- 一番下にRPGツクールMVの素材に変換された画像が表示されるので右クリックして「名前を付けて画像を保存」
- １～３を気が済むまで繰り返す（複数の画像を一気に変換することも可能。出力画像は一番下にどんどん追加されていきます）
※拡大方式別のサンプルを見たかったり、拡大倍率の使い分け方を知りたい場合は変換器のサンプルと解説（RPGツクールMV製）をご覧ください。
・顔グラフィック設定（拡大方式は「ブラウザ標準」、拡大倍率は「３倍」で固定。ぼやけ気味なのでwaifu2x-caffeなどでの拡大をおすすめします）
