the cd card for PCE isn't a bios per say. there's a bios on the PCE, and in the cd rom drive, but the card was used in the place of a PCE game to use CD games.
If you have zero knowledge about the system you're trying to emulate with an alpha emulator with no official release yet, how on earth are you expecting thing to work out in your favor ?
kinda baffles me...
This is not a general Retroarch support threead, it's for ppl to report WII U ONLY RELATED BUGS/ERROR FOR THOSE EARLY BUILDS, NOT FOR FEVS TO SHOVEL THROUGH POSTS THAT ARE 99% USELESS.
are we going to post this every 5 posts ?
1) Test your ROMs on PC Retroarch FIRST (you will need the exact romset, not a random one, the right one)
2)
http://wiki.libretro.com/ (you can't expect things to work without reading this)
3) have a little knowledge/some grasp about the system you're trying to emulate. Are you new to emulation ? it's fine, but why on earth would you try to learn about emulation with alpha builds ? this does not make a single ounce of sense. USE EMULATORS THAT ARE STABLE AND KNOWN TO WORK FIRST. (ie not on Wii U)
4) ONLY THEN, POST HERE
I won't put words on the developer's mouth, but I'll just leave you with this analogy :
how would you feel if you were asking for ppl about feedback you latest work, that...well, needs work, and ppl's input, and 99% of ppl comments are about ppl not getting you older stuff to work, older stuff that is documented, but obviously not there, because that's not the point at all of why you asked for feedback in the first place.
How would YOU feel ? discouraged ? not feeling like reading the whole thing and missing actual feedback ?
I personally only you and to stop with the analogy, they, the devs know.
