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.
===GX4000: Compatible with cartridges but not the device===
===PlayCity: Partially compatible===
Contrarily to Unlike the [[PlayCity]], the Play2CPC is not equipped with a Z80 Counter Timer Circuit 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 obscure soundchip, the OPN3 (ymf288). It offers 3 SSG chans, 6 FM 4-op chans and 6 digidrum chans.
The PlayCity is instead equipped with 2 SSG soundchips offering a total of 6 SSG chans, but no FM and no digidrum chans.
So the few PlayCity programs using 9ch AY will be not replayed by the Play2CPC.
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.
Games So, games like [http://theswordofianna.retroworks.es/ The Sword of Ianna] won't work on the Play2CPC.
