大きい画面無性にほしくなってとりあえず安物でいいやと
7インチのX40Proを買ってみた

安物ゆえ心配してたけど
フルスクリーンとスケールの切り替え設定あった
キーマッピング設定あった
スティック押し込みできてL3R3があった
方向キーが4分裂だけどUSBにレトロフリークコントローラー差したら使えた
スピーカーは2ヶ所ある
初めて7インチ体験とにかくデカくて迫力ある
今のところ買って後悔はしてない

セールで激安5.1インチのX50Maxも買った
こいつも悪くなくX40ProからL2R2L3R3省いて5.1インチになっただけ
メーカー不詳な謎のXシリーズの中ではコスパ最強だと思う

SF2000/GB300/M17/R36sあたりは安くて注目されてるけど
謎XシリーズのX40Pro/X50Maxもそれらの仲間いれてあげて

Suddenly felt the urge for a larger screen and decided to go for something cheap for now. Bought the 7-inch X40Pro.

Was worried because it's cheap, but:
- It had settings to switch between full screen and scale.
- It had key mapping settings.
- It had L3R3 buttons by pressing the sticks.
- Although the directional buttons were divided into four, I could use them by plugging in a Retro Freak controller to the USB.
- It has speakers in two places.
- First time experiencing a 7-inch screen, it's huge and impressive.
- So far, no regrets after buying it.

Also bought the super cheap 5.1-inch X50Max on sale.
It's not bad either, just removed L2R2 and L3R3 from X40Pro and became 5.1 inches.
Among the mysterious X series, I think it's the best cost performance.

SF2000/GB300/M17/R36s are also attracting attention for being cheap, but I'd include the mysterious X series X40Pro/X50Max among them.
