Here is an example of why you should not leave your precious CPC games lying on the floor of your bedroom, within reach of a bored German Shepherd dog:

I bought this copy of Teodoro No Sabe Volar at RetroMadrid for €10, and now I will have to pay €10 + postage to buy another copy! >:(
Still, I must take some share of the blame for not tidying up my bedroom! :laugh:
For the record, children can do the same, as I've seen with..... 20-30 DVD movie covers of ours. ::)
Lucky it wasn't the last copy of Hisoft's Art In Pascal. :-X
Well German Shepards and kids do obviously serve an educational purpose and support the forces of order (by creating chaos, which in turn forces the owners to increase their level of order).
Damn! Where can I buy one? :D
Kids? Oh, you get them here in NOLA for a couple of beeres ;) [nb]Excluded from exchange[/nb]

From the Retroworks shop (http://www.retroworks.es/shop/).

Interesting if you want the MSX version extra 10€, what are we (Amstrad owners) missing? :o

The MSX version is supplied as a cartridge, not a cassette.
Turn your German Shepherd dog into a nice furr carpet, sell it on eBay for 10€uros (+ shippings) and get yourself another Theodoro... ;D

Wow, they can do MSX cartridges ?
When will they announce they can produce PLUS/GX4000's 512K cartridges?
MSX Cartridges don't have an ACID chip.
Bryce.
Nope. But they can have SCC+ chips and any other custom chip from Konami.... ;D

??? I thought Cassettes were hard to get these days?? :laugh:
Though I suppose the production process of getting a game onto a Cartridge would be more involved Vs. Copying a Tape with the Master tape. :D

Yes, but if your game doesn't use SCC then you don't need it. The CPC+ always needs the ACID.

admitting defeat????
Defeat? Was it a competition? :D
No, I was just making the point that a CPC+ cartridge NEEDS an acid chip, whereas any custom chips in an MSX cartridge are purely optional extras.

I know where we can get 100 of them. :)
No - I won't give a single one away. Buy them by yourself, they have 400 left. :P
My prescious.... :laugh:
Have you tested them to see if they are real? There's an awful lot of fakes going around. I got stung myself lately.
Bryce.
Not now, but the chips look like the real ones and the company has in their list the official Amstrad part number. However I paid 8,20 Euros per chip, which is not cheap at all. But for a really big game in 512 KB ROM it shall be ok.
What is the price to get a new batch produced?
There is a way to reproduce such sort of chips...
the method involve to "sand" slightly the chip and to take picture of each "layer" between each "sanding process"...
Of course it is a destructive process but it would be nice to get this done for both the ACID and the ASIC.
Can't someone working at a university perform this?
Once we really know what is inside those chips, we can even more easily "emulate" them...

Perhaps a company like this one could help as well, what is their fee?

Perhaps there too :

Ok, the ASIC may be very hard to do because certainly quite miniaturised and a lot of content and we actually destroy a PLUS machine in each process...
But the ACID must really be simple I guess, or is it not?
sorry if I'm being out of topic again.
Cool, I've got some sandpaper left from some wood work I did, and I also have a camera. Bring it on!

We already know what they do, so I'm not sure what this gets us.
BTW, Octoate's algorithm can be further optimised... if you work out what each term is doing, it actually simplifies quite a bit more, although I haven't published any details because I haven't actually been able to test it yet...
During the last Retro Madrid (sorry, i need to get time for writting a post with all the CPC highlights during RM2013), mcleod_ideafix brought a CPC+ flash cartridge with his ACID implementation in CPLD, it was a big success :) We had it all the weekend in a GX4000 with Pang, in the Amstrad User Group stand, and everybody, that stoped there, enjoyed a few minutes of Pang :)
There is a picture of mcleod_ideafix with his creation in the GUA flickr (http://www.flickr.com/photos/grupousuariosamstrad/8555962045/in/photostream/).
