A lot of good work is happening on this forum! This is great, but lately I have had trouble keeping track of some excellent Mac OS hacking by our members. So I have created this topic is to help our hackers show off their own Mac OS work, and stay updated on everybody else's.

Put in as much esoteric detail as you like, but try to apprise us of the overall goal that you are working towards (e.g., adding support for a new machine or extending the RAM limit). Links to your repository are especially welcome, and the more frequent your updates, the better.

I know that Daniel, darthnVader and powermax all have projects on the go right now. Guys, please use this thread to clue us all in.

May I suggest to the mods that they keep track of the work happening here and back it up for us?

[ELN]

I'll start!

My last few days of hacking have been dedicated to the version of the Mac ROM that shipped with the final Classic version in 10.4.11. I have been updating my already mercilessly hacked CubeE sources with the aim of building a byte-perfect replica of that ROM. Check it out here:

https://github.com/elliotnunn/mac-rom/tree/classic

So far, looking at the classic vs master branches, I've noticed three interesting things:

• Lots of FE22 traps have been inserted. This is obviously a call to the Classic Environment (although I don't know how the 68k Emulator handles it). If you look closely, you can see that part of the D0 argument to the trap corresponds with the size of the argument block on the stack!
• It seems to have been forked off from the mainline Mac OS ROM some time before the version in the final tbxi releases.
• Instead of searching for boot blocks on a real disk, the Classic ROM contains its own copy!

I have been trying to leave as much of the master branch unchanged as possible. This is especially tricky in the case of the object files that I ripped using my "unlink" tool (and previously "DeVectorize"). Thanks to a lot of manual guidance, these files are able to be linked at any location without disrupting code references. However, I will probably still have to re-rip a lot of them from the Classic ROM. The reason is that Apple's build system was able to use dead code analysis, while mine is not, because I have an imperfect understanding of the references between branches. It would be *really cool* to produce object files that combine the united set of functions in both ROMs, but it would require me to make some serious changes to the master branch.

[Daniel]

I'll go next.

I have recently figured out how to map the unused memory on 2GB machines into the address space. You may have noticed me ask people to test something called MPMapper a while back. I had figured out how to do it, but a bug in the NanoKernel prevented it from working (It crashes 100% of the time if you run it on an unpatched ROM). I discovered and fixed this bug around a week ago, so we can now map in all the memory (if you have a Mac OS ROM that has the bug fixed. It hasn't been distributed yet).

By itself, this isn't enough to break the 1.5GB 1.625GB (thanks ELN!) barrier. The memory is part if the address space, but it is in its own separate chunk off in the middle of nowhere. You can access it, but the Memory Manager and Process Manager can't use it. I suppose you could tell the Memory Manager to create a private heap zone there, but that would only be useful for the one application that did so.

This is a step of the way there, but we would need to patch the Memory Manager, the Process Manager, and maybe the Virtual Memory Manager to make it usable for the entire system.

[ELN]

Here's a quick plug for enablifier, a Python script that idempotently turns a bootable Mac OS ROM file into a System Enabler, using a template of your choice (some are included).

I have little interest in the System Enabler, which rather annoyingly brings language-specific resources to an otherwise internationalised booter file. But excluding it could theoretically cause subtle bugs in any NewWorld machine. Sometimes, patches to the Enabler resources are even useful, as in iMic's ROMs and my boot 3 patches. Enablifier lets me "enablify" a ROM at arm's length while I hold my nose and avert my gaze.

Currently I’m working on a reverse-engineered source tree for *every* NanoKernel release I can find.

[classicmacreborn7]

Right now, I'm working on a modified OS9 and emulator wrapper that is seamless enough to prevent the user from being reminded that they are in emulation (or perhaps prevent them from even knowing at all).  Fullscreen OS9 apps should just open in a modern OS and seem like they're running natively.  That means the user must be prevented from seeing the OS9 desktop or seeing the startup screen.

I think it's important as the majority of users who come to OS9 emulators are here to play certain games they remember from those days.  Right now, there is no easy way for them to do that.  One of the biggest complaints I hear is about how difficult it is to set up an OS9 emulator- and how they wish there was something like Wineskin for OS9.  There were a lot more mac enthusiasts back in those days than there are OS9 emulator enthusiasts today.  Making it easy will hopefully bring in more people to the community.

I'm using SS for now as boot time is significantly faster.  It will be composed of a couple of components (that I can think of so far):

1. WrapperFinder - a custom finder that launches the application on boot and shuts down the system when the application is quit
(this is my current project).  It should read from a Finder.cfg file to get the location of the application to be launched.

2. SSRelay - a series of scripts that allows data to be passed back and forth between the host OS and guest OS with a decently low latency (< 0.25 seconds at max).  One important feature this allows is for the host OS to set the emulator to invisible until after the guest OS sends it a message that the application has been launched and instead display a custom loading screen generated by the host OS.  This is completed as of now.  However, the host-side scripts need to be rewritten to be cross-platform (only OSX right now).

In the future it needs:
- An OS9 installer for all guest additions.  The installer should load on a virtual drive after installation- the same way VirtualBox does.
- Modifications to SS to display in nearest neighbor scaling instead of ugly linear interpolation.  It should then scale at the largest multiple of the guest OS's resolution that fits within the host OS resolution.
- A setup wizard that allows you to run through the OS9 install process after selecting the install disc and romfile.  It should also have a checkbox that allows you to run a checksum on the disk image to ensure it is the original disk.
- A simple script that sets up the startup disk as read-only and allows you to install the application on a separate virtual drive (to improve the wrapped app's stability).

Everything needs to be as portable as possible, as the user should be able to select their own OS9 install CD to keep it legal.  I don't think most users will have trouble running through OS9 installation, but right now setting up both SS and QEMU are a huge pain- and they really don't have to be.

I'm having a really fun time with this.  Glad I had the chance to right everything out here.

A split trap has an impossible address that starts with 0xFFC.

[Daniel]

The Toolbox ROM is at 0xFFC00000, at least on PowerPCs.

[OS923]

Says who? 0xFFC00000 is negative.

[Daniel]

If you look in the low memory variable ROMBase (0x2aE), it holds 0xFFC00000.

You can view this in MacsBug by typeing @ROMBase.

if you have TattleTech, it will also say the rom is at 0xFFC00000.

Macs have been able to access the upper portion of the 32-bit address space since at least the Mac II.

On PPC Macs, there are quite a few mapped addresses over 0x8000000.

[ELN]

I think that was a NewWorld innovation, or possibly PCI. Having ROMBase over 2 GB exposed some latent bugs where a code address was signed-compared with ROMBase. Most non-ROM code would, this way, seem to be in ROM.

Hey everyone! Finally got Mac Mini G4 to operate in 1920x1080 with 2d/3d support and million of colours on non-Apple Displays. Check this out: http://macos9lives.com/smforum/index.php/topic,5009.0.html

[macStuff]

it sure would be great if we had one champion hacker who could create a bootable sata pci card
if its all done in the firmware; i dont understand why someone cant create a new firmware that will allow to boot macos9;
i mean; what is more important than that?

Take a look at Sonnet Tempo and FirmTek Cards. Also there are some amount of SIL cards on aliexpress.

If you drag an alias to a program, then it receives the spec of the destination, but if you drag an alias to a window that supports drag-and-drop, then it receives the spec of the alias.

If you drag an alias to a CW Pro project, then it adds the destination, and it can be found as long as the destination is in one of the include paths. But if you add a file to a CW Pro project, then you move it so that you can replace it with an alias to that file with the same name, then CW Pro will treat the alias like the original, and the original will be found even if it's not in one of the include paths.

A DeskHook cannot be used anymore to draw the desktop, but it still works for clicking in the desktop.

[OS923]

If you install TechTool Trash Cache, then every program can delete locked files with FSpDelete. Normally FSpDelete should return fLckdErr (-45).

[ELN]

I have added ataboot.py to my tbxi-patches library. This script patches a Mac OS ROM file, enabling startup from an ATA hard disk without the "Mac OS 9 drivers" installed. It only works on NewWorld machines, i.e. those that use the Mac OS ROM file instead of a physical ROM.

https://github.com/elliotnunn/tbxi-patches

This patch can help get Mac OS 8/9 booting from a disk without reformatting it with Drive Setup or a similar utility. This is useful when installing 9 on officially Mac OS X-only machines that shipped without the disk drivers, e.g. the Mac mini.

(At the root of the original problem is the very unusual block storage architecture of the Classic Mac OS. ATAPI devices like optical drives, and SCSI/FW/USB devices, are not affected by the patch. Disks still require an Apple Partition Map.)

[OS923]

If you receive an Apple event and you change the descriptor type to 'meta' then you can iterate a list of attributes that are otherwise invisible. I read this in the source code of the AEGizmos (written by Apple) and this seems to be a hack, because I found no documentation about 'meta'.
