The Namco System 357C variant is actually literally just a PS3 in a metal box with some different firmware running on it.
All of the arcade games have been dumped already, and so that's not an issue. They actually come on HDDs that are automatically booted by the Namco firmware.
I've heard that most will boot up in RPCS3 successfully, but fail because they cannot connect to the USB KEY (which can be patched out) and also the IO. I've unfortunately not managed to get this to work yet as I've been running into some errors with RPCS3 which I'll ask about later on.
I've recently purchased a System 357C and the IO, with the hope of getting the physical IO to work with RPCS3 and then emulating it, so that RPCS3 can support:
- Deadstorm Pirates
- Razing Storm
- Taiko drumming games
- AKB Sailor Zombie
- Dark Escape
Seeing as this seems to be the only post on the matter here, I'll update with my progress unless anyone would prefer I didn't
