I sent you the RCP file for this ROM. The problem with this ROM is that it has its ID number and the manufacturer's name in the ROM's header area. The header area occupies first 16 bytes from the beginning of the ROM:

https://www.msx.org/wiki/Develop_a_program_in_cartridge_ROM

As you can see from the below screenshot, the text produces a few conflicting addresses and if you let all BIOSes initialize before starting this ROM, they will take the fake addresses into use and eventually cause a crash. The solution is to fix the starting sequence so that only the game's ROM is started from Carnivore2 with all other BIOSes being disabled.

Hi there.
Is there any way to add double PSG with Carnivore 2?
I've seen some Enhanced games like Zanac-Ex and Usas using double PSG options.

I think the best is a loader always ignores DEVICE and TEXT for page 1, and STATEMENT and DEVICE for page 2 then make an option for mirror or not. Otherwise, start the game ROMs by a reset and in this case, only the mirror option is useful.

STATEMENT can be ignored too for the page 2.

I'm not sure how you mean gdx. How can I set this up for the Canrivore2 when booting Zanec-Ex?

Starting with pressing G will give me a blank blue screen for Zanac-Ex.

The upcoming release 2.50 has this feature. You can try this feature already. See the open beta test messages in Carnivore2 announcements thread. You will need to update firmware and boot menu.

That's awsome news. Thanks for the invite, but I can wait until final release.
