Change the status of alternate GB/C firmware options to unacceptable. Quoting from CasualPokePlayer "Gambatte is definitely not emulating those cpus [dmg0 and cgb0]. So you would end up with quirks of newer cpus being combined with bootroms only present in older cpus."
Also fix what looks to be a longstanding typo where the PCFX BIOS v1.01 was not being properly detected.
Waterbox supports threads now, but they're not real threads on the host side because that's complicated and can be nondeterministic. Instead, everything is scheduled to share one host thread. This means that scheduling is actually cooperative and certain patterns of spinlocks and other nonsense can fail to work at all, but "regular" code probably will.
With this, add DobieStation PS2 core. This core was selected because it has threads and is otherwise simple to port; easy to build and a good core/frontend separation. It's not a wonderful core however, with low speed (made abysmally lower by our lack of real threads) and low compatibility, so it remains a curiosity for now.
Updated the msx bios filename based on mame 0.221 and cbios0.29a, this way it fixes the filename conflict while using the feature "Organize" through Firmware Manager.
Couldn't figure it out about the bios_test origin, so I kept that one unchanged.
Add 'nyma' project
The goal is to eventually update all of our Mednafen cores. For now, there is a work in progress import of the Mednafen pce core. Basic gameplay with hucard, turbocd, and supergrafix is supported, but the core is not complete yet.
