I've managed to implement the Casper co-pro, the Cumana co-pro and my own creation, the CiscOS copro

It's all still a bit buggy, but it's working for now... If you want to experiment with this, just download the ZIP file and extract it. Currently only a Windows version is available. Since it uses some extra files in the Documents\BeebEm\BeebFile folder, you may need to rename any current Documents\BeebEm folder to Documents\BeebEm.bak. When you now start BeebEm, it wil ask you if it can create a new folder called BeebEm in Documents with all the correct ROM's.
To start the Casper co-pro:
- Start BeebEm
- Go to Hardware -> Edit ROM configuration
- Select an empty slot, and load the Casper6502.rom file
- Go to Hardware - Select second processor and select Casper 68000 Second Processor
- Enter *CASPER
- Start BeebEm
- Go to Hardware -> Edit ROM configuration
- Select an empty slot, and load the Cumana68k.rom file
- Go to Hardware - Select second processor and select Cumana 68k Second Processor
- Enter *OS9
- Start BeebEm
- Go to Hardware - Select second processor and select CiscOS Second Processor
