You can buy an EPROM eraser for the cost of the postage to Ireland and back.

For the same delay, I will retry the free Sun power first.

Sun power ? But it's rainning today

TotO · « **Reply #302 on:** 15:26, 30 July 14 »

Yes, it's the problem since... 6 months. $:-\$

got mine but will be at work between now and Sunday away from home will test it Sunday night I hope

Had a quick go got detected, installed the software now all I need to do is learn how to burn a rom to it that I have to wait til Sunday for...

How to install a ROM? (Well you need the great new super firmware switched on and then...)

Type this:

MEMORY &3FFF
LOAD"EXAMPLE.ROM",&4000
CALL &B8DD,&4000,6

In this case the ROM gets installed to position 6. If you want another number change the "6" in the last line.

TotO · « **Reply #306 on:** 19:23, 31 July 14 »

Update your firmware to 3.15 TFM !!!
It's possible to simply use |FLASH,"EXAMPLE.ROM",6 instead.

TFM · « **Reply #307 on:** 00:38, 01 August 14 »

Thanks!

BTW: Can someone confirm that romam 2.0 runs with the X-MEM? Kangaroo tells that it does, but I have doubts for reasons of SDP.

TotO · « **Reply #308 on:** 09:54, 01 August 14 »

I have to replace the flash IC from Winbond to SST after the need to return 20 "defectives" chips...
As, I was not able to wait 1 month for the exchange.

That means, the FW3.15 and the provided tools support both chips, as well as Megaflash and FlashGordon boards.
So, if you said to encounter problem with ROMAN and SDP, I suggest that tool only support SST IC.

Sorry to be a pain TotO, but I was just wondering when you was thinking of opening the store again? I know that you said before that it will be in august, but if you could give me a heads up, I can try and make sure that I have the money put by to order a X-Mem.

TotO · « **Reply #310 on:** 14:09, 01 August 14 »

Hello !

wait the next week, please.

CPC_Fan · « **Reply #311 on:** 15:39, 01 August 14 »

Ok. Thanks TotO and sorry for my impatience.

Does this mean that some X-MEM have a Winbond and some have a SST Flash?

Yes, and the next release could have even a different flash chip, for the user is not important the technical details while the flash program works perfectly

TFM · « **Reply #314 on:** 22:19, 04 August 14 »

Thanks! Well, it may not be important for all users, but for sure for all programmers of the X-MEM. That's not only ROManager coders, maybe it's time for a Flash-Disc or other stuff. IMHO it's good to make information available for anyone who likes to contribute.

Hello friends,

i have a question please. How can i kill the "Firmware 3.15" Lower Rom and Rom 0 in my X-Mem and how can i turn it to a real CPC464?
I like to flash the "cpc464.rom" into lower rom and i like to flash the "basic 1.0" into the rom 0 place. But i really dont know how to do that. There is nothing about that problem in the help.txt

If the x-mem is turn to CPC the usual CPC6128 with Basic 1.1 should power up, if it is turned to X-mem the real CPC464 with Basic 1.0 and Tape commands should power up.

Is that possible to do with x-mem? Is there an english wiki or help documents about the Flash commands and how to especially access the lower Rom parts?

Is it possible to flash headerless 16kb ROM Files into Lower Rom and ROM 0 too? I dont have Basic 1.0 and 464.rom as 17kb files.

@TFM:
I can confirm that Roman 2.0 really works with X-Mem too. But you need to kill ROM1 with firmware exp. first. If ROM1 is empty ROMAN 2.0 is working. It doesnt work together with the Firmware exp rom.

Kindly Regards and thank you very much for your kind help.
Tom

TotO · « **Reply #316 on:** 22:30, 06 August 14 »

Sure you can by flashing ROM 71 (464 firmware) and ROM 64 (464 BASIC).
The best is to use the tools from the SIDE B of the floppy. There was made for!

The RUN"INSTALL" process will ask you the wished BASIC (1.0 or 1.1) and your keyboard layout (EN/FR/SP).
Then, that will automatically install the good files. Nothing more to do.

Pentagon · « **Reply #317 on:** 22:42, 06 August 14 »

Thank you so much, that helped a lot and it worked. Now i have a real working CPC464 at a usual 6128. So it should play the original sorcery tape now.

Merci!
Tom

TotO · « **Reply #318 on:** 22:53, 06 August 14 »

You are welcome!

The X-MEM was made for that. Have fun!!!

(you probably missed the end of the README.TXT file. )

Pentagon · « **Reply #319 on:** 22:54, 06 August 14 »

Another Noob question, please forgive

It's not possible to switch off ROM 7 to get a pure CPC464 without Amsdos, cause the internal CPC6128 Amsdos ROM7 is always be initialized?
Or does anybody know a special hint to switch off internal and external #07?

Sorcery Tape doesnt work with Amsdos together

Thank you very much for help
Tom

TotO · « **Reply #320 on:** 23:02, 06 August 14 »

Sadly, the 6128 not allow to disable ROM7.

It's strange to read that Sorcery not run because AMSDOS is installed. $:-\$
I have to investigate about that. It's not X-MEM related. (but software)

EDIT:
May be disabling AMSDOS with some pokes...

Pentagon · « **Reply #321 on:** 23:15, 06 August 14 »

No this issue is not X-Mem related, it's a software problem with the 464 Sorcery tape. The Flash loader crash at the first headerless part loading. Same at the real CPC464, you can't load the tape with a plugged DDI-I Interface. If you plug off and just run a pure unexpanded CPC the tape loads fine. I do have an very early 1983 CPC464 Board to confirm and an 1985 CPC6128 with X-Mem and internal SD-HxC.

There are some other games like "Country Cottages german" or "Quiwi" running on pure 464 only.

The X-Mem is running fine, your guys are genius. Thanks a lot for that awesome piece of hardware.

Merci
Tom

TotO · « **Reply #322 on:** 23:22, 06 August 14 »

Thank you for those informations.
I will keep you informed if something can help to run your original game.

Sure. Install f.e. X-DDOS at position 6. Then enter "!ROMON" without parameters, the result is a CPC with only BASIC (ROM 0) initialized, but not ROM 7 (or any other ROM).

I believe utopia and/or protext do the same.
