NEC的PC Engine GT，也被稱為TurboExpress，是於1990年推出的一款掌上遊戲機。是PC Engine（在美國稱為TurboGrafx-16）的可攜式版本，並且能夠直接運行家用主機遊戲的掌機，在當時的市場中顯得相當前衛和強大。

硬體規格非常先進。配備一個2.6英寸的背光TFT LCD顯示屏，解析度為400×270像素，可以顯示出極為細緻的畫面。其內部處理器是8位元的Hudson Soft HuC6280，運行頻率為7.16 MHz，與PC Engine家用主機相同。能夠直接讀取家用主機使用的HuCard遊戲卡，這意味著玩家可以在掌機上遊玩與家用主機完全相同的遊戲，這在當時是非常罕見的功能。還配備立體聲揚聲器和耳機插孔，音效表現出色。然而，主機也並不是沒有缺點。首先是體積相對較大，但與當時的其他掌機相比攜帶不太方便。其次，電池續航能力不佳，使用六顆AA電池僅能維持約3到4小時的遊玩時間，這使得玩家在外出遊玩時需要頻繁更換電池。此外，儘管擁有出色的硬體規格，但其價格非常昂貴，這在一定程度上限制其市場接受度。

在遊戲方面，可以運行PC Engine家用主機的所有HuCard遊戲，這使得遊戲陣容上擁有豐富的選擇。其中一些經典作品包括《PC原人》（Bonk's Adventure）、《機甲戰士》（GUNHED / Blazing Lazers）、《惡魔城：血之輪迴》（Castlevania: Rondo of Blood）以及《戰斧傳說》（Legendary Axe）。這些遊戲涵蓋動作、射擊、平台等多種遊戲類型，提供多樣化的遊戲體驗。儘管擁有強大的性能和豐富的遊戲陣容，但銷售表現並不理想。其高昂的售價和短暫的電池壽命使得許多消費者對這款產品望而卻步。此外，當時市場上還有其他強有力的競爭對手，如任天堂的Game Boy和世嘉的Game Gear，它們在價格、電池壽命和遊戲陣容等方面都對PC Engine GT構成挑戰。最終，PC Engine GT的銷售數量僅為150萬台，遠遠不及PC Engine家用主機的表現。

總體來說，這是充滿創新的掌上遊戲機，為玩家提供便攜式遊玩家用主機遊戲的可能性。然而，其昂貴的價格和短暫的電池壽命使得這款產品在市場上未能獲得廣泛的認可。儘管如此，PC Engine GT仍然在遊戲歷史中留下獨特的印記，並被視為掌機市場早期的一次重要嘗試。

The PC Engine GT, also known as the TurboExpress in the United States, was a handheld gaming console released by NEC in 1990. It was the portable version of the PC Engine (known as the TurboGrafx-16 in the U.S.) and had the unique ability to play home console games directly on a handheld device, making it highly advanced and powerful for its time.

The hardware specifications were notably cutting-edge. The PC Engine GT was equipped with a 2.6-inch backlit TFT LCD screen with a resolution of 400×270 pixels, capable of displaying remarkably detailed visuals. The internal processor was an 8-bit Hudson Soft HuC6280, running at a frequency of 7.16 MHz, identical to the PC Engine home console. The handheld could directly read HuCard game cards used by the home console, allowing players to enjoy the same games on the go, which was an exceptionally rare feature at the time. It also featured stereo speakers and a headphone jack, providing excellent audio performance.

However, the device was not without its drawbacks. First, its relatively large size made it less portable compared to other handheld consoles of the era. Secondly, the battery life was poor, requiring six AA batteries to sustain only about 3 to 4 hours of gameplay, meaning players had to frequently replace batteries when playing on the go. Additionally, despite its impressive hardware specs, the console was quite expensive, which limited its market appeal.

In terms of games, the PC Engine GT could run all HuCard games from the PC Engine home console, offering a wide selection of titles. Some classic games included Bonk's Adventure (PC原人), GUNHED / Blazing Lazers (機甲戰士), Castlevania: Rondo of Blood (惡魔城：血之輪迴), and Legendary Axe (戰斧傳說). These games spanned various genres such as action, shooting, and platforming, providing a diverse gaming experience.

Despite its powerful performance and rich game library, the sales performance of the PC Engine GT was less than stellar. Its high price and short battery life deterred many potential buyers. Additionally, there were strong competitors in the market at the time, such as Nintendo's Game Boy and Sega's Game Gear, which offered advantages in price, battery life, and game selection, presenting significant challenges to the PC Engine GT. Ultimately, the PC Engine GT sold only about 1.5 million units, far less than the PC Engine home console's performance.

Overall, the PC Engine GT was a handheld console full of innovation, offering players the possibility of enjoying home console games in a portable format. However, its expensive price tag and short battery life prevented it from gaining widespread recognition in the market. Despite this, the PC Engine GT remains a unique part of gaming history and is seen as an important early attempt in the handheld gaming market.
