* Detect orphaned state-vN.bin and offer file recovery to a host folder
When STATE_VERSION is bumped, users previously lost their C:\ silently.
The Welcome card now detects an older state file (v4+), explains what
happened, and offers a one-click recovery: spin up a throwaway v86
(no boot), restore the legacy state to populate the hda dirty-block
overlay, walk the FAT32 tree reading overlay-if-dirty-else-base, and
copy any file the guest ever wrote out to ~/Downloads/Recovered C Drive.
Directories are created lazily so empty branches never appear; success
and failure render in the panel (no native dialogs). The geometry
constraint that keeps overlay+new-base valid is documented next to
STATE_VERSION. Also makes the dev-mode CDP port overridable via
WIN95_DEBUG_PORT so worktree instances don't fight over 9222.
* prettier
* Add "Boot from scratch" to the Machine menu
Wires a new MACHINE_BOOT_FROM_SCRATCH IPC command from the app menu to the existing Emulator.bootFromScratch() handler, so users can start a fresh boot without going through the settings card. Enabled only while the machine is stopped, matching Start.
* Rename menu item to "Start without state"
* Move "Send key" items below power management in Machine menu
* Seamless mouse via VMware backdoor + fs-backed TOOLS share
v86 (rebuilt libv86.js from fork branch vmware-mouse): new VMwareMouse
device on port 0x5658 implementing GETVERSION/ABSPOINTER_* fed by the
existing mouse-absolute bus event. Move-only packets are coalesced so
the guest cursor never falls more than one frame behind. Emits
vmware-absolute-mouse on the bus when the guest driver toggles mode.
Renderer: listens for that event, keeps the v86 mouse enabled without
pointer lock, drops the startup auto-capture, and hides the host cursor
over the canvas (.seamless-mouse) while the driver is active. Falls back
to click-to-capture when no driver is present.
SMB: TOOLS share is now backed by the bundled guest-tools/ directory
(subdirectories work) with the synthetic README.TXT/_MAPZ.BAT overlaid
at the root. resolve() routes by tid; SEARCH and FIND_FIRST2 share a
single listForSearch helper.
guest-tools/mouse-driver/: VBMOUSE.EXE + VBMOUSE.DRV from VBADOS
(Javier S. Pedro, GPLv2). Load the TSR from AUTOEXEC.BAT and set
mouse.drv=vbmouse.drv in SYSTEM.INI to enable seamless mouse.
Also: tsconfig rootDir "." for TS 6.0 (preserves dist/src/ layout).
* docs: windows95-base now includes vmware-abspointer
Windows 95 can now mount a host folder as a network drive at \\HOST\HOST.
Read-only, ~1500 lines, zero deps. Defaults to ~/Downloads, configurable in
Settings.
Protocol: NEGOTIATE (LANMAN2.1), SESSION_SETUP, TREE_CONNECT, TRANSACTION/RAP
(NetShareEnum, NetServerGetInfo, NetWkstaGetInfo), TRANSACTION2/FIND_FIRST2,
SEARCH (8.3 with ~N suffix mapping), OPEN_ANDX, NT_CREATE_ANDX, READ_ANDX,
CLOSE, QUERY_INFORMATION, CHECK_DIRECTORY. NetBIOS Name Service on UDP 137
answers Node Status and Name Query so \\HOST resolves.
v86 hook: monkeypatches adapter.on_tcp_connection (old API), shadows
adapter.receive during a port-80 probe to steal a TCPConnection without
side effects, re-aims it at port 139. Data via .on_data (Closure
dead-code-eliminated .on/.emit). Also registers tcp-connection bus event
for newer v86 builds.
Security: read-only, path traversal blocked lexically and through symlinks
(realpath the deepest existing ancestor, re-append tail, confirm under root).
Share path validated in main-process IPC.
BIOS updated to SeaBIOS 1.16.2 (compatible with old v86). v86 itself stays
on the Feb 2025 prod build — newer builds hang at the splash screen on fresh
boot (bisect tooling included in tools/).
Also: tools/update-v86.js builds wasm+libv86+BIOS from a local v86 checkout
and refuses to install JS/wasm pairs more than 14 days apart (copy.sh ships
mismatched pairs). tools/parcel-build.js dynamic-import patch made tolerant
of post-d4c5fa86 builds.
