Yeah it is not going to be big, but it is time scale and list of priorities.
If it was a quick two minute try and succeed then it would be different, but if it is a try and fail, then it will frustrate me and even if it took days to try and succeed, then that is time that I do not currently have. If it was a system that I actually wanted to do anyway, then that would have been another matter.
At the moment I have X amount of systems to set up, and currently doing 2,900 PS1 Japan Roms
This is about the 1,000th thing on my list to do, in that I may never get around to ever doing this system, or if I do it might be ten years before I touch this.
However, you really need to look at the Amstrad CPC and other tape based systems, that really is the only help that I can give you on this system.
It just does not even come close to my radar to do, e.g it is a system that I have never used, heard of etc.
Hermintage Potter or however you spell his name, has not been on for a while, or AKAFox, they would have been your best people to have tried this for you.
Hopefully if they have the time to try this, then they might be able to get it up and running for you, but as I say have a look at tape based systems, it might be a similar style set up in what you need to do.
E.G it needs to insert tape, run/load tape and play the game.
A few things that you could try
-f = full screen (do not put the = full screen just use -f
-L = load I would assume
-run=system -rom=[name]
A couple of systems that I could find, I could not find an Amstrad CPC or reasonably anything close to that, ZX Spectrum might be close to that
I just had a look at retroarch
They have the following cores
PC-8000 - 8800
PC-98
PC-FX
No 6001VX though who knows that might be a waiting game if they ever release a core for this system.
