Compatibility
C4CPC: Compatible
The C4CPC can already be used on the Plus2CPC and Play2CPC cartridge adapters.
The Plus2CPC and Play2CPC allow to program a compatible blank cartridge from the CPC. No USB plug needed.
PlayCity: Partially compatible
The Play2CPC does not have a CTC chip, as opposed to the PlayCity which includes a CTC chip. The Play2CPC use the default configuration of most of the PlayCity programs, like ALCON 2020.
Sound capabilities are also quite different. The Play2CPC is equipped with an OPN3 (ymf288) soundchip. It offers 3 PSG chans, 6 FM chans and 6 adpcm rhythm chans. The PlayCity is equipped with 2 PSG soundchips offering a total of 6 PSG chans, but zero FM and adpcm rhythm chans.
So the few PlayCity programs using 9ch AY will be not replayed by the Play2CPC. Also, programs using the FM and adpcm rhythm capabilities of the Play2CPC will not be replayed on the PlayCity.
Dandanator: Not compatible
It is not compatible, because the Play2CPC use Amstrad standard ROM paging and cartridge for new CPC games, while the Dandanator use Game Boy Advance cartridge with a custom ROM paging through Z80 opcodes for new Speccy ports.
GX4000: Compatible with cartridges but not the device
The Play2CPC is not usable on the GX4000 because the GX4000 does not have an expansion port.
The device itself must be connected to a computer, but the cartridges you write can be later used on a GX4000.
