OmegaGB Nintendo Game Boy Emulator By Bit Connor [email protected]

=== Requirements:

• ghc 6.6
• gtk2hs (with glade support) 0.9.11 These are the versions I am using. Other versions should probably also work fine. If you don't have gtk2hs then you can still run the Ascii tests, which do ascii art rendering to your terminal.

=== About

This is still in a very rough state. The priority right now is to optimize the code so that it will run in real time. Right now it runs at about 10% of real time speed on my workstation.

There are still lots of pieces missing for full emulation:

• CPU emulation is almost complete, but it may be buggy
• The memory bus still needs a bit of work. Currently there is no support for any of the GB memory banks, so only 32K ROMS have a chance at running. Also missing are a bunch of the various GB registers.
• Only a few of the GB interrupts have been implemented.
• The only part of the graphics hardware that is emulated so far is rendering of the background map.
• No sound emulation.
• No link cable emulation.

What all this means is that OmegaGB is capable of showing the title screens of a few games, but not much more.

The goal is to get OmegaGB to a state where it can properly emulate most games. If you don't have a way to dump your game cartdriges to a rom file (and don't want to download), then you can get some free (legal) roms at this website:

I've found that SPACE.GB from the "Diagnostics Rom", by an unknown author works well. Also, the title screen shows for "Sokoban", by Obsession Development.
