Running the startup file dra4.bat of Dragon Knight 4 with DOSBox 6.1 under XP, there are a large number of missing texts in options and dialogues after entering the game. For example, the item name "Power Seed" is displayed as "力 种子" in the game. The DOSBox settings are all default settings. After installing the full version of MS-DOS 7.1 under XP and running dra4 in the pure DOS system, the words "cpu error, incorrect opcode, killing processing" appear, and it is completely impossible to enter the game. The installation of MS-DOS 7.1 is complete, and the sound card driver is also installed normally. I don't know how to play the game smoothly.
