The stuff can be found in the `asm` folder. \nYou can compile an asm file (like `examples/inc_hlt.asm`) using `customasm.exe` and then use the generated output and load that into ram.\n\nNOTE: You need to include the `common.asm` file for customasm to work properly!\n\nNOTE: If you are not on windows, you will need to get customasm and then it should hopefully work too.\n\n## Images/GIFs\n![An image of the full cpu](./imgs/image.png)\n\n![The cpu running a test program that adds 1 to the first register until it reaches 0x20](./imgs/cpu%20test%201.gif)\n\n\n## Thanks to\n* [Phoenix v2](https://github.com/Glowman554/phoenix-v2)\n* [Customasm](https://github.com/hlorenzi/customasm)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmarceldobehere%2Fgoofy-cpu","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmarceldobehere%2Fgoofy-cpu","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmarceldobehere%2Fgoofy-cpu/lists"}
