But you have to do a power cycle to have the cartridge menu. A reset will reset the cpc/gx4000, not the cartridge emulator.

Yes.
The cartridge port only have address, data and read signal. Nothing that could be used to detect a reset.
The menu itself is a cartridge (CprSelect.cpr) that is loaded from the SD card at power on.

And what about soft reset?. If we are copying the firmware with the dsk. Is not possible modify thefirmware subroutine to changue the buttons, 1+2+p for example and made a soft reset.(if the game permit it of curse).Insead of ctr+alt+(i don't remember now).

I i remember o.k in a plus you can made a soft reset when you are  play burning rubber(in the original cartridge)

A soft reset is just a simple jump to the reset vector. The cartridge emulator cannot detect this reliably.

Ok, so the solution in your case yurif74 is have a reset button in the expansion port. I know the are manufactured to the cpc normal, but i not sure in plus case. If you search  preserve the swith on/off.

The hard-reset button on the expansion port won't get you the menu either. As Gerald has said "the cartridge needs a power cycle" No matter what sort of reset you do, if the 5Vs isn't removed from the cartridge it won't reset to menu.

Have to say, you guys sure are making the GX4000 seem a lot more appealing.  :)

I would build a workaround to the problem using an electronic reset system that will reset the GX4000 and remove and reapply power to pins B18 and A18, this is easy to do, but i do not exactly know how to do an hard reset on the GX4000 since it doesn't have an expansion slot!!!

The CPC has a perfectly good power switch, why would you need that?

Saint Dragon uses direct floppy disc controller access. That is not supported and I can't detect that.

Same with Dragon breed. it too is using direct floppy disc controller access.

I don't need it, i only help. Anyway, the swtich of plus can broke at longer time. As with c4cpc is normal swtichg on/off much more...

Ok, so saint dragon and dragon breed discarted.

yurif74

i was playing with dragons lair and i notice it is unplyable on GX4000 because you have to press space to jump.. a space to fire 2 fix is needed

CraigsBar

I played some of these over the weekend. And some suffer from power cycle to get through the high score table entry. These games should be demoted to need fix right?
