MS-DOS
Ordinary DOS ZIPs are converted locally into the js-dos bundle format the emulator expects. R26 loads ordinary DOS ZIPs directly into the js-dos virtual filesystem. It also strips a single wrapper folder automatically, so archives such as F-15 Strike Eagle II can find their EXE/COM files at C:\ without manual repacking.

Select a normal DOS game ZIP or a ready-made .jsdos bundle. For normal ZIPs, Barefoot creates the required .jsdos/dosbox.conf in memory before starting the emulator. Your local file stays in your browser unless you deliberately put it in the private ROM Locker.
