I think we had this discussion many times and you should better stop saying that is PCB dependant.There is NO WAY to disable the internal AMSDOS ROM on ANY 6128 PCBe supposed to work
Wait that made me think. So let's focus on Parados for now. Using X-mem if I put it in slot 6, will it override the IO disk handling of internal Amsdos rom on slot 7? So is there a point for replacing the rom 7 at all if I aim for external hardware like x-mem?
You can be sorry If you're with TFM on this, can you list how to identify a CPC that will work without any doubt with an external ROM7, without first plugging the extension ?
Yes, we hat that discussion often enough. The SF2 and the RRB can replace the ROM 7, which works for me, Toklkin, Mr.Ams, BrainBlaster, Prodatron and a lot of others.

That's not true. I never replaced my Rom7 with the SYMBiFACE II.
I did some tests to find why many Amstrad Plus demos don't work correctly if my X-mem is connected, but i didn't really find any way to solve the problem.

Can anyone confirm me the same problem?This test has been made with my last demo "revival'n impact cooperation" in the part 1. You could find the dsk here
Does not work with the XMEM nor my own memory extension.Are you sure you only use C0-C7 memory banks (1st 64K block of extension RAM) and not others ? Without the XMEM you always reach the 1st 64k extension block, whatever you select.
Yes, i only use c0,c4,c5,c6 and c7 with port #7f...Synergy Demo and xMas 2008 do the same thing...
Maybe yes... But what?Unfortunately this intro by Roudoudou does the same thing...Problem is only on amstrad plus, i think.Edit:Same problem with Mario+ and Shadow of the Beast+ who can only work without x-mem.... It's so strange!
No problems. Thanks.
nothing obvious. both using asic pri.both using expansion ram normally.@Ast: Did you try x-mem and 464Plus?I wonder if there is a conflict between ram on x-mem and internal 6128plus extra ram.@gerald: I think it's a coincidence that demo doesn't work on arnold wip. It's using split screen and scroll quite heavily.
@gerald: I enabled I/o breakpoints in arnold debugger, set it to "dk'tronics ram compatible write" and it will break on the i/o write to select the ram. Then look at the IOAddr and value in the details to see the port and data that the z80 saw if it's not obvious from the dissassembly. I could see it was only these writes.
