The core is replaced by dosbox-core as of libretro/dosbox-core d38fcb50 (its history is in that repository), with the following on top: - Frontend VFS for mounted drives (libretro/dosbox-core#11): Android content:// and saf:// content works. - Built as dosbox_libretro and called DOSBox, so it installs next to dosbox-core without sharing its options, saves directory or config file. Option keys keep their dosbox_core_ prefix. - ZIP files as content, from DOSBox Pure (Bernhard Schelling): its zipDrive, unionDrive and memoryDrive, and the helpers they share (drive_dbp.cpp). The archive is mounted as C: without being extracted and the game's changes go to <name>.save.zip in the saves directory. DOS_Drive and DOS_File get the few members those drives need, with defaults. - The game in a ZIP is started when there is nothing to choose: the single program in the root, or in the one folder the root holds, leaving setup and install programs aside. - Disk images inside a ZIP: CD images (cue sheets with data and audio tracks, or ISOs) as D:, floppy images as A:, hard disk images as E: and on. Files on emulated drives can be named "$C:\PATH" as in DOSBox Pure; host_stat, fopen_wrap, the CD image reader and the audio track decoder open them through the drive, finding files by their long names. CDs and floppies go to RetroArch's disc control. - A start menu after DOSBox Pure's when a ZIP leaves a choice: it lists the programs on C: and on the mounted images, starts the one picked, can make it start on its own next time (kept in C:\DOSBOX.RUN, in the save file), and comes back when the program exits. Keyboard and gamepad; it can be turned off in the core options. - Automatic gamepad mapping from DOSBox Pure's Keyb2Joypad database (original data by Jemy Murphy and bigjim, used by DOSBox Pure with permission): a game the database knows, as a ZIP or from a directory, gets its keys, mouse and joystick actions on the first gamepad instead of the DOS joystick, with the action names shown in RetroArch. It can be turned off. - The CPU speed from the game's year, from its name or the database, as in DOSBox Pure; it can be turned off. - Roland SC-55 MIDI with Nuked-SC55 (nukeykt), from DOSBox Pure, as a new MIDI driver taking the module's ROMs from the system directory.
