Estimated 8086 timings for reassembling PSR Invaders.

In other words, NASM16 (or even MININASM) is too slow for reassembling the whole source file at once (2000 lines) on an actual 8086. Although many programmers shun splitting everything into separate .OBJ files for LINK, realistically that's what most projects would require (unless you're just super patient). In theory, I would like to profile NASM16 and fix it.

In lieu of common NASM syntax, you can use other assemblers, but they have their own tradeoffs.
