The list of 1292 families is at: https://en.wikipedia...le_Video_Systemin Compatibility family which relates to cart slot used. The VC-4000 was mainly just released in Germany. Some may dispute it was released in other parts of Europe (perhaps as a German import) but I have only ever seen them selling from germany on EBay, with most German sellers only shipping to Germany which makes it more difficult to aquire a decend condition working unit and the usual over-priced sellers seilling worldwide that I want to avoid.


The 1292 Advanced Programmable Video System was the most popular cart type. At least it was in the UK with the common systems being Radofin, Prinztronic and Acetronic. This would probably be the best type to make.


Actually just noticed some idiot has changed that table and added Database Videomaster (Voltmace) to the 1292 Advanced Programmable Video System which is wrong. The Databse was a machine in its own family and a different sized cart and pin layout.

The Bally Astrocade already has devices out for it.


The Tomy Tutor\Pyuuta is probably the best bet as it had both a Japanese and USA release ands sold in both computer and console form and is probably the most owned niche console. All games have now been dumped for it. I heard rumours someone was making a flash cart for this, was asked not to say anything at the time, but it was so long back I am guessing that is now abandonware.


The Epoch/Yeno Super Cassette Vision multicart would also be welcome. A very underated system with some good games on it, approx 30 carts and a couple of quite rare (and expensive) ones. This was more popular in Japan, but also saw a small release in France. However a few carts took AA batteries and had the ability to save games, so I am not sure if those would work and one cart was a basic programmer with some games on it.


A Casio PV-1000 multicart would also be welcome, but has less games released. I am still unsure if Casio PV-2000 dumped games would also work on a PV-1000 (or with slight modification), but if so that would also increase the library.


The other Casio Cart system - The Casio Loopy - Lets forget this as all but one of the games are easy to come by and all were in Japanese only making them hard to use for non japanese.


I found no real evidence a multicart for the APF MP-1000 ever existed after searching on the yahoo group, but I do not own one of these so have no interest in it at the moment. Perhaps one was made as a homebrew project, but no public release?


I'd say avoid the Thomson MO-5/MO-6/TO-7 machines for a cart device. The majority of TO-7 and MO-5 games were released on Tape. The device I have seen for the MO-5 was only made as homebrew with no public release and only a handful of games were converted to SD format to work with it. You also had to write or load a small basic program to access the device. While better than nothing it did not look ideal at all. Not much was released for the MO-6 at all but still a facinating system as it was also released in Italy. The best machine is the TO-8 with games released on disk, meaning you can replace the floppy drive with a Gotek to get access to games without messing about with floppies, so no need for anything for that. The other French system which had a handful of games released on cart was the Exelvision EXL 100. The best resource for the French systems is http://dcmoto.free.f...html/index.htmland under Support for MEMO5 and MEMO7 to see cart based images. There is also a lot of games on the French systems which are surpisingly in the French Language requiring knowing written French to be able to play.


The VG-5000 does not have any device, but was tape based games only. Other systems which do not have a device but were tape based only include The Matra Alice, Camputers Lynx, EACA Colour Genie, Hector HR (and variants), Sanyo PHC 25, Sharp MZ700 and VTech Laser 200 and 300. While the Oric has had a disk based SD device released for it, with the majority of games being on tape, never being released of converted to disk and no easy way of converting the games to disk it is almost a useless device so I would also add that to the list of tape based machines with no device. The other issue with some of these machines is that the games loaded in parts using the pause feature of the REM(ote) input on the tape decks to pause the tape and restart it to load the next part. Quite a few games on the French systems did this where they would load a instructions page before continuing to load the main game.


Another computer which only had a few cart games released was the pre-MSX Spectravideo SV-318 and SV-328, with the majority of games released on tape, and has no cart based system at all.


The big one which might be impossible for a cart of this type and need something more custom like a everdrive is the Funtech Super A'Can with games being rarer than the system its one I have had difficulty in finding games at any price. And of course the Atari Jaguar which would need a similarly complex cart, and the Atari 7800 which seems to have become abandonware yet again after the carts creator has gone AWOL.


Whatever you decide, it would be most welcome.

Having read this thread and others on the subject, it appears that between the test models he sold at PRGE, and the remaining ones that were sold off to the board in batches there are approximately 40-50 concerto carts in the wild. And of them, only 2 documented cases of complete failure, 1 being Kosmic Stardust, and one other that was sold? Most others reported fairly consistent results with all the commercial roms, and some scattered issues with pokey attached to the concerto or homebrew roms.

Sounds like a pretty useful beta phase. Pity Batari hasn't been around for updates in some time.


That many minus one, remembering the crazy posts about that idiot who bastardised his cart cutting pins, rather than selling it to someone else who really wanted one. What a twat.

I think its great news some new games are being made for the system.


To be honest I would not worry about people ripping off the cartridges. The 1292 systems are only really sought by die hard retro collectors and have little commercial value. Any carts made would have to be on a hobby basis and I doubt many people would pay premium prices for new games for the system.


The only multicart made for the system is by Rolo for the VC4000 German system, and only works with games without extra RAM. You may want to contact him if you want to test a game on a real system, so he can burn to a ROM and test.



While I now have the multicart, I do not own the system. I own a modded VC-6000 which has the more common 1292 port. Voltmace did also make a Database Cart to 1292 cartridge convertor, and while I own one they are hard to come by and I have only ever seen two for sale.


With all the different console families having different sized cartridge ports and no one willing to make convertors, the market will be limited at this time, most likely to people in Germany, unless on a hobby basis someone decides to make a small batch of dedicated carts.

Uuups, I'm too slow, obviously! :-o  :sleep: :-D

The Dragon/CoCo multi-cart to INTERTON ELECTRONICS VC4000 Video Computer Extension now is available!

I made another extension cartridge for the Dragon/CoCo Multi-cart.


Both cartridges connected:

Connected to the INTERTON Extension cartridge, the multi-cartridge is capable of playing roms on the INTERTON VC4000, which do not require extra cartridge RAM (i.e. AI-games like Chess, Backgammon, etc.). Even some non-INTERTON roms are running. ;-) 
I checked these roms:

Game               INTERTON

Chess 1...............13         not running
Chess 2...............22         not running
Draughts..............26         not running
Backgammon............36         not running
Spider's Web..........37         not running (bad rom-file?)
Hobby Module..........Acetronic  not running
Come-Frutas...........TRQ        not running
Come-Frutas...........TRQ        not running

The Dragon/CoCo Multi-cartridge to INTERTON VC4000 Extension cartridge for US$12.99 plus shipping!

(Dragon/CoCo Multi-cartridge NOT included!)





I am sure you have seen it, but there is a page at http://amigan.1emu.net/igg/which lists all variations between the 1292 systems and some instructions.


From memory Crazy Crab is a sprite hack of Spider's Web (which was also known as Monster-Man) and the Hobby Module cart was a programmer so the cart probably was a bit different.
