Quote from: steve on 14:52, 17 August 10I think the problem is the ACID chip, and getting the cartridges manufactured.There was a thread that told of a supplier who had 500 genuine ACID chips in stock, but no-one seems to have bought them, at least if they have they are keeping quiet about it.If ACID chips are not available then they must be cloned, apparently the secrets of the ACID chip have been cracked by a Spanish group but I don't know where any details about this are to be found, hopefully it will go in CPCWIKI eventually.Finally you want someone to produce a run of cartridge casings, some people in Poland are changing the ROMs in genuine Amstrad cartridges, but that is not a viable long term solution.

Quote from: jbaudrand on 21:24, 17 August 10thanks for explanation, so if I understand correctly, I could store variable in RAM for quest/game progress/score and access to ROM for loading different level or totally new kind of game. My actual skill didn't allow me to understand the 16k ROM access with Z80.
Quote from: jbaudrand link=topic=578.msg12221#msg12221 date=1282069472I have only a simple 6128, so I will stay on disc for my little game.
Quote from: jbaudrand link=topic=578.msg12221#msg12221 date=1282069472 for making real cartridge, the team from Atari Age or nintendo age can build cartridge from scratch, and I've seen on the web a guy who made James Bond Lego from scratch, so I believe there's a affordable tool that exist for creating plastic case but I don't know where to ask for.for Acid chip: is it just a common eprom or not?
Quote from: TFM/FS on 04:38, 19 August 10Universe has a funny timeing. Got an email today, they offered me the ACID for 7,86 Euro each (if I take 100). Keep you informed...
Quote from: jbaudrand on 08:41, 19 August 10TFM/FS: they still build them? or is it an old stock?
Quote from: arnoldemu on 11:21, 19 August 10beware of fake ics. There are some fake SIDs going around, and some of them are not even close to being real sids.If these are genuine then if I could use it to test my own cartridge games then I would have one.
Quote from: TFM/FS on 21:23, 19 August 10 Yes, it's from 1992. Well, for c64 all you get is a fake ;-) Because it's no CPC. However I got a lightly better price now (it still hurts, but what can you do), it's 6,85 Euros for a piece if you take 100. So I ordered 100. May they rip me off or send me fake IC's - can happen, then I'll take my consequences But I hope everything will work out well.
Quote from: steve on 13:47, 20 August 10Could you offer an extended cartridge that has an exposed ZIF socket so we could easily and quickly change the 512KB rom and reduce the need for one ACID chip for each ROM.
Quote from: arnoldemu on 14:00, 20 August 10For me I would like some way to be able to reprogram the cartridge, so having flash or static ram on it and an easy way to download data onto it. This would be the best, because then I could easily test my programs are working.I don't have eproms or tools to write them.
Quote from: TFM/FS on 22:09, 20 August 10Don't know what you mean with a ZIP socket, is it like a Textool socket? However I was indeed thinking about such things. But like mentioned before, the ACID is one component, the remaining parts of the cardridge are still missing. The biggest problem is to get the plastig cover. Does anybody know where we can get them?
Quote from: Gryzor on 10:31, 23 August 10You bought them???!!! I think we should have all pooled some money to get them... unless you're planning to use them and sell some sort of product in the future, which is of course very much OK.
