Plenty left, I managed to get hold of 80 FlashROMs so I ordered enough parts for them all. I think I'm up to 30+ , so far :D

I have build a RGB to SCART cable today and tested mine. It works great! Good to see those old games again.
Unfortunately my Elk crashes after playing games for a while and I have unplug the power about five minutes and then it works again for about 10 minutes. But that's something for another topic - after I have reseated the ULA. IIRC it's an UK Electron. The German Electrons works fine with the MGC so the cartridge is not the problem.

Great work David and others that have worked on it.

BTW is there also a search option for finding games?

If it's a UK Electron then it's probably just being lazy. ;) Actually, I wonder if it might not be a different type of ULA to the ones in the German Electrons - perhaps those were supplied with later variants that were more reliable.

Thanks! It was fun to help with the project, though a lot more effort than I imagined it would be at the start.

I think the others are working on adding a search option to the menu. It's not my area of responsibility. :D

Another difference is that the ula in the German Elk is soldered on the board. Not in a socket. That makes it also more reliable.

Roland . . .

You can list Games with a known first letter by using option 2 "Games Alphabetically". I don't have plans to add a search option for individual Games! Too complicated search code and, probably, not enough room left.

I've just updated the Spreadsheet here, as the MGC now supports Utilities and Applications . . .

If you have any ROMs that aren't listed please pm me with the details - thanks.

Great work on this project guys. =D>

I was wondering would it be easy to emulate this particular device in B-EM
so more people can play with the code and make their own compilations?
Not the same as plugging one into a real elk or master of course, but for future projects
using the hardware, ( Like that giant 4mb game! ) it might be an idea.

Good luck with that, Hedge . . . If you or anyone taking up the mantle(?) needs any assistance just shout.

That's because you didn't have 25 posts. You should be able to PM now though!

As a quick hack for testing purposes, I changed Elkulator to expose different banks of data depending on the value written to address FC00. It should be pretty straightforward to do something similar for B-Em. Of course, it doesn't simulate the hardware with any accuracy, and the register at FC08 needs to be handled, but for simple tests it works reasonably well.

Wow, I only just stumbled upon this.
This looks awesome.
I don't have enough posts to PM you, so will email.

Cheers,
