Release v1.3.0 · dividebysandwich/rust-dos

What's new

Games can now come with their own gamepad mapping: a [gamepad] section in the profile, or the input_pad_* / input_wheel_* lines of a package's DOS.YML.
Each pad input (D-pad, A/B/X/Y, shoulders, triggers, L3/R3, Select/Start and the stick directions) can press up to four keys, mouse moves or clicks, or joystick moves and buttons, e.g. start=leftctrl+f10 Open Menu.
An input bound to wheel opens a radial action wheel over the game while held. The left stick (or D-pad) picks a slice, and releasing the button triggers it.
Mouse speed (padmousespeed, mousespeed, mousexfactor) and the host mouse wheel (mousewheelup/mousewheeldown) can be set per game.
On desktop the first gamepad uses the game's mapping. In the libretro core, it applies to port 1 set to Gamepad as keyboard.
P on the Games page lists a game's mapping.

A .dosc file's launch configurations ([Setup Program], [Ship Editor], [General MIDI Music]...) are offered in a chooser when the game is launched. Tools like the setup program are marked.
Combined options such as [MIDI + German] are picked with Left/Right on the game's row.
When a tool ends, the chooser opens again. All launch configurations share the game's saves.
Works with the keyboard and mouse on desktop and with the gamepad in RetroArch.

A GAME.conf next to GAME.zip or GAME.dosz is now used even if it only has an [autoexec] section.
The package is mounted as C: before the conf's commands run, so REMOUNT C D, SUBST C: X:\GAMEDIR and mounting another C: work as these confs expect.
A .dosz, or an archive with a .conf or .dosc of its name next to it, keeps the archive's root as C:, so cd GAMEDIR lines keep working.
A GAME.dosc is layered over its game. Its DOS.YML sets CPU speed, CPU type, memory, video card, sound card, MIDI synth, the program to start, images to mount or boot, the keys pressed at startup and the gamepad mapping.
IPS, BPS and VCDIFF (xdelta) patches in a .dosc are applied to the game's files. XOR patches are reported in the log and skipped.
Loading or importing a .dosc loads its game.
Package profiles now track what they were made from: when you edit the .conf (or add a .dosc), the profile is rebuilt the next time the game loads, keeping its saves.

[game] input= (or DOS.YML's run_input) types keys once the game's program has started, e.g. input=(WAIT:200)(ENTER)(WAITMODECHANGE).
Supports typed text, (KEY) presses, (key:DOWN)/(key:UP), (WAIT:ms), (WAITMODECHANGE) and (DELAY:ms).
Waits run in emulated time, and the machine fast-forwards through them. Pressing a key or pad button stops the sequence.

Hard disk images in ~/.config/rust-dos/os (libretro: system/rust-dos/os) can be mounted by name: IMGMOUNT C WIN98SE or REMOUNT WIN98SE C. REMOUNT on its own lists them.
[rust-dos] os=win98se in a game's conf boots the game inside that OS: the image is the first hard disk and the game is D:. Other emulators ignore that section, so one conf works in both.
A new Boot OS core option in the libretro core does the same for packages without a conf.
The OS image is never written: each game's changes go to its own delta file, so one install serves every game.

REMOUNT from to moves a mounted drive to another letter. REMOUNT C D leaves C: empty for an OS image.
SUBST drive: path makes a folder a drive of its own, and SUBST drive: /D removes it.

The DOS prompt now edits its line like clink: move and delete anywhere in the line, word keys, overwrite and undo.
Colors for commands, programs, switches and arguments. PROMPT can use ANSI colors after $E, e.g. PROMPT $E[1;33m$P$E[0m$G.
Suggests the rest of the line from history (Right or End accepts).
Tab completes commands, PATH programs, files, directories and variables. Ctrl+Space lists the matches.
History is kept between sessions. PgUp/PgDn/F8 search it by prefix, Ctrl+R/Ctrl+S search it incrementally, and F7 shows it in a window. The new HISTORY command lists or clears it.
This feature is configurable in the new [shell] section of the config
The settings window now has toggles for suggestions, colors and history - in case you prefer an authentic DOS experience over convenience

OpenGL rendering is now behind a gl feature (on by default). Builds without it, e.g. on RedoxOS the SDL renderer is used.
Steam uses a different file extension for their cd image cue files. This is now supported as well. Tested with Steam's Descent 2 distribution - which works perfectly too btw ;)

Fixed a game's drives being swapped back (in RetroArch, to an empty drive_c folder) when its commands started no program
When a game ends, every drive it changed is restored, including ones changed by REMOUNT or SUBST
Fixed imported BOOT C: lines being treated as an image path
Relative paths in a conf next to an archive are now also looked up in the archive's folder
Fixed files in some DOS-made zips showing up as folders (Commander Keen 1's INSTALL.EXE)
