Also, the Internet Archive's overall "emulation experience" is often not very faithful. Their rendering of "Adventures
in Math" gives the impression that the game ran *much* faster than it actually ran on a 4.77Mhz IBM PC.
While the Internet Archive's emulator can be configured operate at different speeds, it's unclear which of their
holdings have already been "tuned". As a fallback, they do provide some user controls:
> "While the program is running, press CTRL-F11 to slow the program down. Pressing CTRL-F11 repeatedly will slow it
down further, until the speed is more reasonable. (Pressing CTRL-F12 repeatedly will attempt to speed things up.)"
but in general, the user has no idea what speed they have currently selected, or what the target speed should be.
For users who simply want "to play the game," that may be fine, but an historian would probably prefer to see how the
game originally operated and how each screen was painstakingly rendered, to better understand both the original user
experience and the challenges that early software developers faced.
