The memory part is from the original project and is a mess, but kept since it works (subsequent rewrites haven't worked). Right now the chipset registers are stored as a seprate structure (but in future I will probably allocate the memory for them in the actual 16meg space). Almost all memory access to this space is big endian, where my plan is that the upper address space will be native endian. Within this 16meg space, there are four descrete areas, the 'Chipram", the "CIA" chips, the custom "chipset" registers, and the ROM. It is built around a core set of functions which manage memory access to the lower 16 megabytes of the system address space (For the time being the upper address space isn't accesible, since that adds a whole level of complexity).

The current code base is a mixture of the original "Zorro" project with one coding style which was hacked together to "just work"(tm) and the project rewrite with a different coding style, making the code very messy. So I decided that a half pun, half tongue in cheek name of Omega was probably better than Zorro (which has other meanings in the Amiga world). It seems unlikely there will be any more Amiga emulators, this could well be the last. In retrospect choosing a simpler machine (like the Atari ST or classic Mac) would probably have been a better idea, as Amiga emulators are difficult to get working and nothing will ever come close to the functionlity of (Win)UAE. Since the only real hardware coding I have done on a 68k machine was with the Amiga, that is the machine I knew best to emulate. This is how the Omega project was born, although I initially called it Zorro (after one of the Commodore Amiga prototypes). As the project developed, I realised that since I needed a set of functions to do the byte swapping to and from the memory there was no reason why I couldn't trap calls to certan addresses an emulate extra hardware functionality required to get an old 68k OS booting. I decided to use the Musashi 68k emulator as the basis as I had used it in another project so had the source code working in "raw C" (no support libraries or host OS functions) and knew the emulator well.

There are plenty of popular "old school" 68k operating systems out there (TOS, Classic Mac, AmigaOS) with lots of great software, why can't I run these on the raspberryPi without a host OS?Īfter the birth of my daughter, I found I had some free time so I set about trying to make a RaspberryPi kernel which was nothing but a 68000 emulator running on the bare metal, with full access to the RaspberryPi address space. So my mind wandered what would it be like if the RaspberryPI had a 68000 CPU instead of an ARM?

This project started around December 2017, when I was doing some bare metal coding on the RaspberryPi.Īfter getting a basic kernel booting I realised I had no software to run, the killer of all hobbyOS projects. The key to the right of the left-shift key will force the emulator to quit. Press F5 to toggle the on screen graphics. A small graphic of the inserted disk will show in the bottom left corner of the screen (the grpahic shows the spin of each disk, and drive head position). Once the emulator is running, hit F1 to "insert" the adf image into DF0: the emulator will now boot the disk.Ĭurrently the emulator is able to boot to Workbench 1.3 (up to 4 ADF can be specified in the command line), to trigger a disk insertion event, press the associated F key (F1 for DF0: | F2 for DF1: | F3 for DF2: | F4 for DF3:). Run this with the options kickstart.rom bootdisk.adf so it will look something like:Īny KS1.x or KS2.x rom will work (256k or 512k), Currently Kickstart 3.x is unable to boot to GUI. This will build and link a file called omega. h files to a single directory, open a comandline cd into it, and then type:Ĭlang *.c -o omega -Iinclude -Lib -lSDL2 -LSDL2main To build on Linux, I use clang (but any c compiler will do), copy all the.

Omega only needs a basic install of libSDL 2 to be installed on your system.
