I have taken it upon myself to alter this emulator, in order to prevent a lot of faffing about with assembling code. I have pre-assembled the Oric1 and Atmos assembly code, both without the slower HI-res mode, and have created the Source.LogAdd file. Other than that the emulator is exactly as I received it.
This means, that the emulator is now ready to use as soon as dearchived. To load the game provided (Defense force) just double-click on the file.
