^ That's true. The Jr. was the slowest member of the PC family (mostly due to its memory architecture), so most speed-sensitive PCjr games need a very low cycle count in DOSBox. Sometimes down to 150 or so.
PCem is another emulator that does PCjr, but DOSBox is much more convenient when you need to go through a large pile of software quickly, and it's very much compatible with PCjr stuff as long as you configure "machine=" and "cycles=" correctly.
