Welcome!
I think that you'd find it a fun machine to program for, with a very developer-friendly architecture.
More interesting than the PlayStation 1, and much less crazy than the Saturn.
I would be interested to port some of my games on PC-FX, the problem is, how many people actually have a PC-FX and are willing to buy new games ?
You'd probably be better off asking that in the main "PC-FX Discussion" section, because not all PC-FX players/collectors are interested in the "Development" section.
I suspect that a lot of PC-FX owners would be open to new games ... the problem is that even here, there really aren't that many active PC-FX owners.
The PC-FX is quite expensive, and because most of the games are unplayable, and the playable ones are expensive too, I guess not much people possess this console. (that the reasons I hesitate to buy one)
If you get a used one without-box from sellers in Japan, I don't personally think that the PC-FX itself is that expensive, and surface shipping isn't that bad (but slow).
If you want a boxed one in perfect condition, and you want it fast, then it'll cost one heck of a lot more!
It's cute to have a PC-FX GA, but it isn't actually needed for development unless you want to write code for the 3D chip ... and so limit yourself to the dozen or less people on the planet with a working PC-FX GA setup.
You can develop quite happily in Mednafen while waiting for real hardware to arrive ... Ryphecha's emulation accuracy is excellent, and it's a nicer development environment than the PC-FX GA anyway.
And since the machine has absolutely no copy-protection, you can burn a CD and run anything that you like and try it before deciding whether you want to buy it.
If there is at least 100~150 people interested, I might consider working on this machine.
That's your decision to make.
If you're interested in being an early developer of Western PC-FX homebrew, and you're not afraid of the challenge of working on a machine that is still fairly unknown, and you're willing to try to puzzle your way through Japanese hardware manuals, then you're in the right place at the right time.
If you're looking for major recognition and some financial reward for your efforts ... then this might not be the best machine for you.
Can the current liberis library play audio cd ? Movie ?
No, I'm afraid not.
You can see Alex's liberis documentation, and his English copy of the documentation that the Japanese homebrew guys put together in 2000/2001 at
http://daifukkat.su/pcfx/If you really want to develop on the PC-FX right now, Hudson's old PC-FX GA libraries are supposed to work with the old Japanese GCC 2.95 toolchain.
I believe that they were supposed to be limited to only run on the PC-FX GA, but that's
probably just in the C startup code, which you could replace.
I'm specifically avoiding the use of those old libraries moving forward, because I want to have a 100% legal toolchain that can be used for homebrew.
AFAIK, that would make it the only 5th-gen machine with a completely legal toolchain ... but I could easily be wrong on that, and would be happy to be corrected.
