Solved Bios systems not working need help

[Russell Biering]

I'm using recalbox on a dell optiplex 755 with a flash drive. I've put all the games that use roms and no bios but when I add games the need a bios they don't work just go to the black screen then goes back to the menu. I've put my bios file in the bios folder I've made a folder of the system in the bios I've put the bios in the roms folder and nothing works I've try psx fds dreamcast and no geo they want work at all. If any one can help me out I would appreciate it very much I want to play my CD base consoles and other bios systems.

The bios files are very particular and its easy to not have the correct ones.

This page tells you the correct names and case the bios files should be in. It also has the md5 hash so you can see how it compares to your file.

@russell-biering don't ask for copyrighted content, thank you.

@russell-biering

What's the name of the bios file you are using (type it exactly as it appears on your recalbox)? Also paste the md5 hash for the file you have.

Lets focus on one psx game for right now. What game are you trying to play and what file format is it in?

Does any game on any system work? What about the games that come preinstalled?

[Russell Biering]

@ivwshane I've tried medevil and I put the rom in the rom folder and it shows up in the folder. Then I put the bios the I had it's the sch1001 bios and put it in the bios folder. I loaded it and it shows the game in list but I when I go to play the game it goes black and goes back to the menu.

@russell-biering what is the md5 hash

[ivwshane]

@russell-biering

The md5 hash (a series of numbers) is posted in that link I posted.

Download and install this program:
http://www.winmd5.com

Run the program and drag the bios file you have onto the top box of the program. It will process the file and then display a hash # and if your bios is the same as the required one then your number should match the # on the page I posted earlier.

[Russell Biering]

@ivwshane I did all of that. What all is going in the bios folder. I put all the right bios for Sega CD in the bios folder I check the md5 hash and the ones I put in there match the ones on the wiki page and it still did work. Psx work because I change to emulators and core but it still says missing bios but it works so what am I doing wrong

[ivwshane]

@russell-biering

I'm not sure how it can work but still give you a missing bios error, unless the game and bios are from a different region.

Maybe you can post your log file.

As long as your MD5 hash is OK, bios will works.
You just need to have the correct typo whicht is requested : as exemple "dc_boot.bin" and not "DC-boot.bin"

[Substring]

@russell-biering go to http://recalbox to check your bios

[Russell Biering]

@ivwshane it while trying the psx it say missing bios file in yellow and runs the game perfect

[Russell Biering]

@substring I've did this and have the correct bios. I did it with the Sega CD. I put every bios the md5 program and everyone the match it I but in my bios folder and it still didn't work and I have both my cue and bin of the game in the roms folder

[Russell Biering]

@ivwshane tell me what I have to after I check the md5 and put it in my bios folder.

[Substring]

@russell-biering then drop roms, carefully read the readme.txt in each rom folder

[Russell Biering]

@substring I've done this and it still does work. I got psx to work with one game and it has a cue and bin file. But when I do another game with a cue and two bin files that say track one and track two. I've got Sega CD to run but psx just doesn't work right. And don't get me started on the 3do I have the right bios that's on the wiki and md5 hash matches and it want play at all. And I read every read me for these two and they say you need iso. .cue . Bin and tried all

[Substring]

@russell-biering recalbox is case sensitive. If the cue files reference some unexistng bib files, it can't work. Make sure files are properly named (case sensitive ...)

[Russell Biering]

@substring can you give me sample of what it should look like
