(I'm the developer of Boxer.)

You're right - Boxer's homepage did actually acknowledge DOSBox until a couple of days ago, when I rewrote most of the copy and in the process took it out. I now realise this was caddish of me, and have added the acknowledgement back in.

It wasn't my intention to take credit for DOSBox's work; it’s an excellent emulator and responsible for 90% of what Boxer does. However, it's also extremely painful to use on the Mac - and I wanted to avoid the suggestion that Boxer's user experience was like that of DOSBox’s.

As airolson noted, DOSBox is also prominently credited within Boxer itself.
