DOOR 09 // x86 DOS LAB
MS-DOS
Ordinary DOS ZIPs are converted locally into the js-dos bundle format the emulator expects. R21 does this with a tiny built-in ZIP patcher, so it no longer depends on the external wlibzip.js helper that returned 404.
C:\> INSERT GAME
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.

At a DOS prompt:
DIR lists files, CD FOLDER enters a directory, CD.. goes back, and a program normally starts by typing its .EXE, .COM or .BAT name. Your Fâ15 ZIP contains a single executable named F15.COM, so R21 recognises that archive automatically. More DOS help âWhy the old Fâ15 upload failed: js-dos requires
.jsdos/dosbox.conf inside its bundle. A normal ZIP does not have it. R21 adds the required js-dos metadata directly to the ZIP in memory; it no longer depends on the failing wlibzip.js bundle-builder. If a game needs special configuration, keep it in the ROM Locker and we can give that title a dedicated profile later.
