* 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
Negotiate NT LM 0.12 (17-word response, Capabilities=0) so Win95 switches
from CMD_SEARCH (8.3-only) to TRANS2/FIND_FIRST2. Implement info level
0x104 (FILE_BOTH_DIRECTORY_INFO) with the win9x quirks Samba carries:
honor SearchCount/MaxDataCount (VREDIR drops the session if exceeded),
4-byte-align entries and the trans2 reply param/data blocks, dir
EndOfFile=0, FileName null-terminated with the null counted in
FileNameLength, and ShortNameLength=0 (a UCS-2 ShortName in an OEM
session GPFs shell32 on the single-directory probe Explorer does when
entering a subfolder). Add TRANS2_QUERY_FS_INFO (0x105/1/2), SMB_COM_SEEK
and core SMB_COM_READ, which the redirector falls back to with no
CAP_LARGE_READX. Sanitize >0xFF / Windows-reserved chars in display names
so emoji folder names don't truncate to '<' and wedge Explorer.
The user share is now named after path.basename of the mounted folder
(LANMAN-safe, ≤12 chars, with TOOLS/IPC$ collision avoided). A second
purely-synthetic TOOLS share holds _MAPZ.BAT and README.TXT so they
don't clutter the user's directory; treeConnect routes by share name to
a TID and every path-resolving handler branches on it so TOOLS never
touches the host fs.
48 protocol tests; verified end-to-end in the emulator (browse \\HOST,
open both shares, list Downloads with 85+ mixed-name entries, navigate
subfolders, open files in Notepad).
Patches src/ide.js before building: restores the dual master+slave writes
for ATA Command Block registers (Features, Sector Count, LBA Low/Mid/High)
that 1b90d2e7 changed to current_interface-only. Those registers are
channel-shared per ATA spec; Win95's ESDI_506.PDR writes them then switches
drive-select expecting the values to persist. Found via JS-only bisect.
Boots fresh in ~32s with the same sporadic-bluescreen rate as the prod build.
The new build has the tcp-connection bus event so SMB uses the clean path
instead of the connection-theft hack (guard added for the old-API monkeypatch
to skip if the bus handler already accepted).
tools/update-v86.js applies the source patch automatically. v86 checkout
left clean (patch stashed).
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.
