used in the TurboExpress was another source for problems, though it was state of the art when it was released. The LCD technology used was still fairly new and the rate of pixel failure was very high. Brand-new TurboExpress systems often had several bad pixels. Text is also difficult or impossible to read in certain circumstances, as many times fonts were written to be seen on a television screen, not on a small LCD screen. As a result, certain RPGs and adventure games can be difficult to play on the unit. The TurboExpress plays the same game cartridges as the TurboGrafx-16 home console. Some TurboGrafx-16 HuCards save game data to the internal memory of the TurboGrafx-CD unit, TurboDuo, or TurboBooster Plus (a peripheral for the core TG-16 console). The TurboExpress lacks this internal memory and, as a result, is not capable of saving in this manner. Most games provide a password save mechanism as an alternative. The battery life is about three hours for 6 AA batteries. This is also a problem for other color and backlit or sidelit handhelds of the time, such as the Game Gear at 5–6 hours, the Sega Nomad at 2–3 hours, and the Atari Lynx at more than 4 hours. Nintendo's Game Boy had a 12- to 40-hour lifespan on 4 AA batteries.

Falcon, a flight simulator, includes "head-to-head" dogfight and cooperative modes that can only be accessed via TurboLink. This technology was also used for Bomberman '93 Com-Link multiplayer. It was released after the TurboExpress launch. However, very few TG-16 games offer co-op play modes especially designed with the TurboExpress in mind. TurboVision TurboVision is a TV tuner adapter for the TurboExpress converting the TurboExpress into an handheld television. The accessory was available at launch for US$100. It allowed a player to either watch television, or go back to playing games with the flip of a switch; in other words, one may use the TurboExpress as a video monitor. It includes an RCA audio/video input for external composite video signals. However, due to the widespread adoption of digital television and the HDTV standard, the adapter will no longer function as a television
