@rbaker said in Where to copy Mame Bios?:

What is "mamebios" by the way?

Nintendo's failed attempt at Mario's evil twin before Wario came on the scene?

Than you for the quick response! Problem solved
: )

@k-shaps said in MAME Setup help:

I already read through that. I guess my question is what can I do for games that are supposed to work with certain bios and are not? Did I just get bad ROM files?

i mean, if you've read it you already know you have bad rom files ;) do you see .75b listed anywhere on that page as a romset that the mame emulators we ship with use? get the right romset for the emulator you want to use first.

@cerealspiller delete the retroarch.cfg. Then reinstall the psx emulator to get your retroarch.cfg back.

You don't have to unzip ADFs. UAE4Arm can load ZIP, ADF, DMS, EXE, ADZ and RP9 formats in the floppy drives.

I have updated the wiki to reflect this.

@kisu2012 said in Controller Dreamcast works in BIOS but not in game:

Hi, TitQuentin
If you have problems for mapping your controller, you have a script called "reicast-joyconfig" for mapping any standard controller.
I use a bluetooth cheap controller and I run this script and works great with reicast.
You have further information on Wiki Retropie reicast at the end of the page.

Excuse my english ,
Good luck

Thank you, it works thanks to your help!

@kamikadzem22 Thank you! I know this is old, but I signed up just to say thanks! This is what solved my issue. :)

If you want to run the games from USB you need to edit some settings. I think you didn't do that and thats the reason why it doesn't work. How large is your SD card?

Just found a way to do something, by using Select+X while in the game: from there, a Quick Menu allows me to see the options you mentioned (but not the rom I added, so you may be right about the static options). Anyway, not sure any change I make here is persistent...

Thanks for the heads up!
After searching the forum I discovered I just needed to put the four bios files in the roms folder.

Cheers

This is a tough question to answer because it can depend on which emulators you installed after a fresh install of RetroPie 4.0.2.

Just for fun I mounted the retropie-4.0.2-rpi2_rpi3.img file and browsed to the /home/pi/RetroPie/BIOS directory and here's the only files I saw:

fast.bin skip.bin system.bin

Make sure you've got everything backed up before proceeding!!!

Maybe you can just move all the other BIOS files into a Temp directory and then just run the RetroPie Setup Script and then Update All Installed Packages. Maybe that'll reinstall all the other stock BIOS files. I don't know if it will work but it's worth a shot.

If all else fails, just reimage and reload the ROM and BIOS files that you actually want.

@Ethan64 you could have saved yourself a few more hours by reading the documentation in the first place: https://github.com/retropie/retropie-setup/wiki/First-Installation#emulationstation

My version of scph5500.bin has the correct MD5 checksum of 8dd7d5296a650fac7319bce665a6a53c and the CRC32 checksom of ff3eeb8c

I think it might be a filename issue. I'll experiment with added a dash in it like scph-5500.bin

Edit:
I've tried many filename cases but non seam to work when trying to play Japanese games but I did find out that it really doesn't matter what case the BIOS files are to play the US games and also worked with just about every BIOS version (US games playing with any J, E and U BIOS files 10x, 100x, 300x, 350x, 500x, 550x, 700x and 750x). Some US games will even play without a BIOS file but it gives a quick message stating "no BIOS found, expect bugs!"

I'm testing with 2 Japanese games: Captian Commando and Nekketsu Oyako. Maybe neither one of these work with the emulator.

Does anyone out there have any Japanese games working and which one(s) did you get working?
