Summer ’22 update

In attempt to increase frequency of status updates on the project after slow progress during the past year, here’s some information about what we’ve been working hard during the summer vacation.

Styled TextEdit updates

One of the most overlooked – but still very important – features has been the Styled TextEdit support. We already had started working on the foundations almost two years ago, and had last year got the drawing to work pretty well (mostly focusing on Marathon’s “computer terminal” screens) – but actual editing features of the styled text have been largely missing. Luckily SimpleText, with its fully-featured styled text editing features, provides a bunch of test cases for a number of them. Below is screenshot of some text styling at work:

Basic styled text editing in SimpleText

Right now, styled text can be finally entered (using various style parameters such as face, font, size), and SimpleText can also open various text documents with styling information. Below is one example, the READ ME file of Prince of Destruction:

Opening a styled text document in SimpleText

But a lot of work needs to be still done, as major features are still unfinished (such as hit-testing of styled text records, which is needed for both mouse click, arrow key and selection support).

“AppleDoubler” tool

Motivation to work on the “AppleDoubler” tool got boost by a question asked in the June on emaculation about our file system choices. We had planned for a long time to make tool for converting native Mac files to the ADF format, but hadn’t taken time to work on that until now. It didn’t actually take more than a couple hours to write (plus some random time to do some tweaks later), but as nice effect we are able now to convert applications for testing blazingly quickly (compared to the manual conversion process earlier). This has led to discovery of a number of bugs which were fixed, and missing special cases of existing features that have been tweaked.

The AppleDoubler tool will be available as soon as we sort out our binary distributions to work a bit better (until now, files have been hosted here on the WP blog, but due to a bunch of issues with executables, and the time-consuming progress of updating downloads page, we will look into more automated alternate solutions, to allow more frequent updates, and also more downloads to be available.)

Software cursor

One longtime “to-do” task has been proper software cursor implementation, which has been delayed mostly because SDL’s cursor API has handled the monochrome cursors quite well for most of the use cases. However, there have been three downsides of this approach:

  1. The “inverted” cursors (such as the I-beam, and Lemming’s cursors) don’t show up properly, as most modern host systems don’t support inversions in cursor graphics. Especially in lemmings this has been tricky in the monochrome mode, as the cursor would appear black on black background, making the game really hard to play
  2. The native cursors don’t show up when doing screenshots of windows, or when capturing in OBS using window capture. This has been mostly prominent on Twitch streams where mouse has been invisible
  3. Color cursor support has been unimplemented, as for proper ‘crsr’ display the mapping of cursor color table needs to be done

The final push for software cursor implementation came when we tried running Super Studio Session editor, which replaces a number of default cursor vectors with its own implementation (which it uses to align the “note” cursor on music sheet at certain spots). We saw that the cursor that application implemented all by itself worked mostly really well, but because of some ShieldCursor bugs, it was leaving trails at certain places. Below are screenshots of Super Studio Session (ignore the “THINK Pascal” window title, we don’t yet have proper general-purpose shell/desktop application yet, so we used the very practical “Transfer” feature of THINK Pascal to launch any application from the file system through Standard File dialog, without needing to do any extra work 😀 )

It took a couple days of work to get the software cursor to work (the work was sped up a lot by a number abstractions we had done earlier, related to VBL task execution etc), and adding color cursor support was not that tough as ‘crsr’ and ‘ppat’ resources share a common heritage, and thus their color table and depth expansion code could be shared. Below are some screenshots of Civilization, showing the color mouse cursor in action:


As a curiosity, in progress of trying out various applications, we noticed that SoftWindows 1.x (the last 68k-compatible version of that application) seems to work pretty well. As it does have quite high memory requirements (considering the currently implemented 24-bit memory manager by default has only 8 megabytes of RAM), we did have to make a temporary hack to boost the RAM limit in the test configuration to 12 megabytes (leaving space for only 3 slots in the emulated slot address space – while the default configuration allows up to 7). This allowed us to actually boot into Windows 3.1 and run a number of games/apps on it (biggest limiting factor for what worked was that this version SoftWindows only emulates a 286, thus allowing only Standard mode in Windows 3, instead of the Enhanced mode required by a lot of applications). Below are some screenshots of what we tried out:

MIDI Manager research

As we knew that certain Sierra games do advertise MT-32 compatibility, we did some quick snooping around, and learned that at least Space Quest 1 does use Apple’s little-known MIDI Manager to handle the hardware MIDI playback (unlike Thexder, which appears to have its own serial driver for MIDI, choosing to use the serial port directly). This led to some curiosity about the MIDI Manager implementation, for which there is sadly very little documentation – an article about programming it on the always valuable MacTech archive and the universal headers. A couple articles from mid 90’s point to ARPA as source to buy the MIDI documentation and SDK from, which sadly is no longer available.

The work on MIDI Manager support is still ongoing, but we feel it might be relatively easy to write a layer that emulates MIDI Manager’s patching features, and wrap the MIDI driver as a abstract device that could pass the MIDI packets to host OS’ native MIDI interface (in Mac OS X case, the CoreMIDI). All MIDI Manager calls go anyway through the same SoundDispatch trap like a number of Sound Manager calls, so tapping to that interface is really easy. (Another question, though, is how well timing will work, and whether default MIDI synthesizer (or the SC-55 midi hardware) will handle Space Quest’s MIDI output that expects an MT-32…)

Various other updates

As mentioned before, there have been a ton of fixes and updates, but here is mention of a couple ones that might be of interest:

Popup Control CDEF (and TextEdit) fixes: There were a number of bugs in both the Popup Control drawing (and TextEdit setup) code, which manifested quite visually in the HyperCard script editor. Below are screenshots of “before” and “after” to show what kind of effects the fixes had:

Menu Bar Pattern Control Panel: As another curiosity, we tried this one old Control Panel from early 90s, to see what would happen – and seems that whatever magic it uses to draw patterns behind menu bar, it seems to be 100% compatible:

Menu Bar Pattern Control Panel

FracSin/FracCos: The After Dark module called “Spotlight” (not to be confused with the OS X search tool) was the first case that needed FracSin/FracCos implementation to work, so we used it as a test case for those traps and got it working pretty well:

After Dark “Spotlight”

Palette fixes: There were a number of bugs & missing features in Palette Manager code (for example, SetEntries had bug that made it fail incorrectly with cProtectErr, which caused a number of issues around the place). Here is Lode Runner: The Legend Returns editor, which had weird color issues before the fix (ignore the palette debugger in bottom right):

Lode Runner: The Legend Returns level editor

BitmapToRegion: This trap was already before used by Escape Velocity, but as that game needs a couple other improvements to reach playable state, Snood worked out pretty well as a use case for this (as it uses it for practically all of its sprites to convert their masks to regions for drawing). After a couple hours, the game seems to be quite happy with the routine (Snood 1.x pictured):

Snood using sprites with masks defined by BitmapToRegion

Default MDEF ‘cicn’ support: While trying out Snood, we noticed that Snood 2 was the first use case of color icons (‘cicn’s) in menu items. As the MDEF already had almost-working handling for this case, we added some temporary code to the Icon Utilities module and got nice color icons in menus now:

Color icons in Snood 2.x Players menu

More blitter fixes/improvements: There were numerous fixes to basic blitters too, which affected test cases such as 3 in Three, “Spotlight” (when brightness was other than 0%), Shanghai II mahjong, etc). Here’s some screenshots of what we got working with the improvements:

Next step

We will continue working on the missing features as always, trying to reach the goal of a generic runtime release as soon as possible. We also will try to find solution for the binary file distribution in near future, so anybody interested trying the new features out could do that as soon as possible (especially considering the last released binaries are already getting quite old). We will keep you updated on this blog on our progress as always.

Marathon fixed & INITs revisited; Fun with Control Panel (cdevs & After Dark)

Marathon color fix

As predicted in the previous post, the culprit for the messed up colors in Marathon was actually just the unfinished implementation of UpdateGWorld. What caused problems in this case was, that the color table in the backbuffer GWorld, which the game uses for off-screen drawing, was created during loading when the intro color table was active, and thus it “inherited” that active color table from the GDevice. However, UpdateGWorld was expected to update new colors from the GDevice when entering the game, and as it was not implemented, that left the old color table intact and messed up the colors. The current implementation of UpdateGWorld handles most of the cases, but does not do the existing pixel data conversion cases, which some applications might required (TODO-assertions were added there though, to signal when we encounter such case).

One handy source (literally!) for debugging Marathon’s backbuffer behaviour was the Marathon source code, which Bungie published quite some time ago at:

Also, we noticed that Marathon has pretty decent support for mouselook, so we enabled the relative mouse mode for test JSON config, and it feels pretty playable with it.

Here are some screenshots of the first level of Marathon running (finally) with proper colors:

Here are also a couple screenshots of one of the demo levels played by the game after staying idle in the main menu:

The first level seems to be completely playable until the end, except that the terminals on the level do not work yet (they require the Styled TextEdit implementation, which still remains on the TODO list – however with quite higher priority now, as so many applications seem to need it already). This is especially tricky as the teleport used at end of the level requires that feature also to pass the level 🙂

INITs revisited

Some time ago, we played around a bit with the INIT loading during startup, and used it to load After Dark screen saver. However, the handling of memory during startup was not optimal; basically BufPtr, which is the top of memory usable for application zone, and 68k stack pointer, were colliding, which caused random crashing.

As the color support is already quite nice for most basic cases (in indexed color modes), we wanted to see how After Dark would work in the color mode, so we did some quick fixing for this. Basically we moved the stack to near middle of the memory range, in a area which was very unlikely to hit the top of system zone, and way below the BufPtr limit, which After Dark wants to lower. This seems to fix that problem for now.

Control Panels

Another important thing we wanted was to allow the After Dark control panel to be usable, so that the screensaver modules could be configured. As we don’t have yet our own control panel to support running cdev resources (the control panels), we temporarily tried out what happens if we run the actual, real Control Panel desk accessory from System 6 – seems that there almost no issues getting this to work, as seen below:

System 6’s “General” Control Panel (cdev) running in the System 6’s Control Panel Desk Accessory (DRVR) running on M.A.C.E.

Surprisingly, bunch of the functionality in “General” control panel was directly working; The desktop pattern editor was almost completely functional, but required implementation of the SetDeskCPat trap, which it uses to apply modified pattern on the desktop. Menu blinking and caret flash controls work directly (as TextEdit and Menu Manager were built to use those low memory globals), and speaker volume control works when run in the “classic” (monochrome Mac Plus style) mode – color version still has the unfinished Sound Manager implementation. The date & time controls show placeholder value as the International Utilities routines are still unfinished, and RAM cache does nothing 🙂

System 6’s “CloseView” Control Panel (cdev) running in the System 6’s Control Panel Desk Accessory (DRVR) running on M.A.C.E.

Even more interestingly, the CloseView control panel (above) also work almost without any fixes; The Key1Trans and Key2Trans low memory procedure pointers were needed to allow shortcut keys to not crash. The zoom controls and zooming work neatly and follow mouse properly, as the cdev does some clever patching of a number of QuickDraw routines, so all the native C drawing is directed to a secondary buffer, which the CloseView cdev draws actually on the screen – when active, it seems to replace WMgrPort and WMgrCPort with the backbuffer, and even modifies ScreenBase to make CopyBits work properly! However, there is still some issue with the algorithm it uses to track “dirty” area, when magnification is off but closeview is active, as it leaves some artifacts on the screen when for example moving windows.

After Dark Control Panel (cdev) running in the System 6’s Control Panel Desk Accessory (DRVR) running on M.A.C.E.

But most importantly, After Dark is now also working. There were a couple fixes needed to make the control panel itself, and some modules, work – such as blend and subpin transfer modes for rectangle blitter, and a number of System 7-type temporary memory handle allocation functions (which for now just directly map to regular handle allocations in the application zone).

But most importantly, the rather complex and deep mix of native C, 68k DRVR, INIT and cdev code with patched traps included, surfaced a rare register trashing condition in the invocation of 68k code from native code – this was only present as a crash when using “Demo” feature of After Dark control panel! The problem was, that as certain 68k procedure calls needed arguments to be passed in registers, they were not saved before the call – and as native C part of the toolbox does not use the 68k registers, and thus does not internally save them, certain 68k -> native -> 68k call combinations resulted with registers being trashed. After adding the fix by implementing proper register save/restore, After Dark is much more stable, and looks great! Here are screenshots of some of the modules which work now (you can click image for larger view):

There are still a number of things to fix though; for example, MultiModule does not work yet (cannot configure modules for some reason), and other modules have unique cases which need to be handled separately (such as “Down the Drain” requiring GetCPixel), and some modules occasionally spitting “Not enough memory” error, but this is good as it provides a lot of test cases for the future!

Also some of the other desk accessories were kind of working and not; some such as “Mouse” control panel won’t have any affect (mouse is right now completely controlled by host operating system), “Monitors” requires proper Slot Manager implementation for handling the graphic devices to not crash, “Color” (probably) needs to have support for modifying the labels in System file, and “Sound” does not do much without Sound Manager. We will in future also try out other cdevs to see what happens 🙂
