Is my ZXUNO faulty?

Mensaje por bakoulis » 11 Ene 2017, 14:16

Is my ZXUNO faulty?
The build-in BIOS games don't works anymore!
I had upgraded many firmware and cores and maybe something was corrupted.
So I decided to restore factory settings. I have flash the big 4.2MB flash.zip on my ZXUNO.
But the problem remains! From the SD card, same games works as it should, from BIOS don't works!

I don't need games on BIOS, but I am afraid is something fault on my ZXUNO.
The screens looks like is a memory fault, but BIOS mem test passed OK.
Also the games works from SD, the problem is present only on BIOS.
Any ideas?

It seems the flash is corrupted only on the ROM games. You can add some game by EAR from here:

If it works, delete the rest of the games and install again. Also you can upgrade by SD with ZX1RomPack

I thought the ZX1RomPack included in 4.2MB file "flash.zip".
Is not included?
Where is the ZX1RomPack file and what upgrade option must select on BIOS to upgrade the ZX1RomPack?

ZX1RomPack is here:
http://www.atc.us.es/svn/zxuno/software/ZX1RomPack/

For update you must use ROMSUPGR utility. Download from here:
http://www.atc.us.es/svn/zxuno/software/upgrade/

Copy the ROMSUPGR file into the BIN folder on your SD and put ROMS.ZX1 on the root. Then boot with a rooted ROM and type:

.romsupgr

Please, make sure that you don't have DivMMC enabled in BIOS. That make ROM games to fail. Use "auto" instead, and make your own rom pack with the divmmc-enabled spectrum roms (machines, not games) you want.

You have right, I have the DivMMC enabled in BIOS!!!!
I don't know this make the games on ROM fail!
I try again tonight but probably the problem was from DivMMC.
Thanks

Yes. But when you upgrade complete FLASH.ZX1 you lose the DivMMC enabled settings. Good luck and thanks Quest for the idea.

No, I don't loose it!!! After flashing, I don't exit without save changes.
The saving before exit, saves also the DivMMC enabled as is before flashing. So the DinMMC remains Enabled!
I will keep the DivMMC enabled to the future because, I don't care about BIOS games, but I will try with "AUTO" to ensure my board isn't faulty.

I hadn't thought about that either, but now it's quite clear: if DivMMC is enabled, it will get activated when the entry points for DivMMC are executed. One of them is address 0066h (NMI entry point), that being a very low address is very likely to be executed in any of those ROMs pretty soon, then DivMMC pages it's code, that is supposed to be paged only on the standard ROM, and all game is messed up.
