Great job slyDC, that is greatly impressive that you managed to secure all the hanimex library... Actually, do you have all the soundic compatible console games (I believe there were 3, including the hanimex, one from soundic and one from lansay)... Do those last 2 systems have games which are unique or Are they all part of the hanimex library?

@ssj: There is a Baseball cartridge on Ebay for 8$ and the seller is in the US: http://www.ebay.com/itm/Epoch-cassette-vision-baseball-US-seller-/161931329940?hash=item25b3dc0194:g:gY4AAOSw-vlVhd1j

This is the cheapest ECV cart i've seen so far. Well someone will surely discover a way to dump one of these "all-in-1" chips and those NEC uPD774C to uPD779C have a program section inside the chips, which i'm assuming 1K or 2K (NEC uPD770C is only a All-in-1 Pong chip used in the Epoch System 10 & 10M2 + the Toshiba TVG-610).

@starlord: Thanks! Well i'm not the only one who has a complete HMG-7900 library and i should be getting the last game this week.
I only have the Hanimex HMG-7900 and the Soundic Programmable Colour Video Game SD-290 so if i want all models, i'm missing the SD-270 (Rollet Videocolor). And there is no unique game titles in their respective library as they use all the same games and they are fully compatible which each others.

I listed all the HMG-7900 clones on the LOVEM.E.S.S. blog but i forgot to mention which model-types they belong to. I'll post a picture with all the model-types very soon.

Yeah I know of that one, I'm not in the US and the guy is asking insane shipping costs for outside US. If anyone wants to pick it up and try to dump it I'll gladly pay for it as I said though.

Ouch I was hoping someone in the US would pick it up as it would be way cheaper, the shipping costs he was asking were ridiculous.

You shouldn't have brought it plgDavid because i can lend you my carts or i can sell you some doubles i have. SSJ is right, shipping cost outside a country is now very ridiculous, i would even say outrageous sometimes (importing/exporting).

The only thing is that i can't bring the stuff to your house as my car has a transmission problem since the beginning of this year, so it's under a pile of snow (looks like an igloo...lol!!).

No worry Sly DC. I'm a compulsive crap buyer.
Just hope the decap can give us a clue on how to dump them.

Sly_DC: I saw this linked from twitter: http://discreteconsoles.blogspot.ca/2015/11/hanimex-hmg-7900-cartridge-pcb-scans.html
and I believe the Motorola chips in those carts are MC6805(or less likely MC6804 which has the same pinout) mask MCU parts. They should all be dumpable, I don't think the mask MC6805 can be protected at all. It is a bit awkward to dump though.

Cheers

He sent me a upD777C-009 about 2 years ago- I bet that's it. I decapped it and made a top metal die shot: www.seanriddle.com/d777_metal.jpg I don't think I ever removed the top metal layer. I've got a better microscope now, so I can clean the die in acid and take another set of top metal pics, then whink it to remove the top metal layer. I can see bits in the ROM, and they'll have more contrast when I remove the top metal layer. I've decapped a few NEC chips and matched visual ROM dumps to Kevtris's electronic ROM dumps, so I might be able to make a visual dump of this one.
