@ma7fouth Okay, let's see if I can help you:
If Wi-Fi still does not work in version 6.0RC2, I recommend that you post the model of your motherboard and the network card, stating the problem in this topic: https://forum.recalbox.com/topic/16941/recalbox-6-0-rc2-is-released
Regarding the BIOS, it is prohibited on the site to request or broadcast any content that has copyright, therefore, you will have to obtain them on your own.
What I can help you on this subject is to direct you to this Wiki link: https://github.com/recalbox/recalbox-os/wiki/Add-system-bios-(EN)
In it says where to put, which names and MD5 CRC are correct for each emulator.
NOTE: The system is case sensitive, so the names and extensions of the BIOS must be exactly the same as what is requested. An easy way to check if the BIOS is being recognized is through Recalbox Manager, but if you are without internet, this is not possible ...
Recalbox does not allow adding new emulators, not for ordinary users. You would have to recompile the system, which is extremely difficult and only the users with advanced knowledge know how to do, basically only the developers do this.
@nwildner Thanks. I did. Seems to work well. I did notice after a reboot the controller didn't work. I was able to plug in another device and get it to work again. I am wondering if I will have to do this everytime.
My name is Adrián de la Torre. I am a graphic and web designer with 5 years of experience. Also i am in a diy project with recalbox, my raspberry pi 3b and an old play station 1, I hope to finish in a few weeks!
@paradadf my network wasn't strong enough for the transfer of files. That's why it wasn't working. I put my usb drive in to pc where I had my roms and transfer them and they worked fine. But roms with multi bin files and one .cue wouldn't work so I just use eboot pdp instead. saves time and space to. Still cant get fds, dreamcast, 3do,pc engine CD are x86k to work.
There isn't solutions except renaming or go back to adf, adf can have CRC (no name needed) where whdload it's harder also you should check with screenscrapper, I had hard times with all the street fighter 2 and had to check insuide teh website to how to name them
