Hello Alexey
Have you thought of a sd / cf driver but with an arduino to manage sd / cf readings?
No, we wanted to have IDE interface and Nextor BIOS only. The CF card fits perfectly for the IDE interface, besides it should be technically possible to connect other IDE devices to the cartridge. If you want to use SD cards, there's always a possibility to use CF-to-SD converter - it's verified to be working correctly.
I see from pictures that Carnivore2 has a jack output, is it plain pin 49 SOUNDIN mono signal routed to 3.5 mm jack? Can it be that a hardware/software mixer solution take control of mixing SCC output with FMPAC's MO and RO outputs towards 3.5 mm jack and/or towards pin 49 SOUNDIN?
Does the MegaFlashROM part of Carnivore2 behave as with a Konami's SCC mapper?

The 3.5mm jack only outputs stereo FMPAC and SCC, there's no PSG there. The 2 channels are mixed into one and are fed to the internal MSX amplifier via SOUNDIN. So you have to use the normal MSX audio output to have all sounds mixed in. Besides this jack is designed as line-out, the headphones will not have enough volume if connected.
The multimapper part of the cartridge supports Konami4, Konami5 (SCC), ASCII 8 and ASCII 16 mappers. Some Korean mappers may be added later. The cartridge can be also used as pure RAM, pure SCC, pure IDE, pure FMPAC or a combination of those devices.

I have not explained well.
I mean a controller (ide or CF), but the load of reading and writing was through an arduino (there are some with 64KB and 16Mhz).

We don't have experience with such platforms. And there are no plans to study them.
