Steps to get rid of Arcade Mame BIOS problem

July 16, 2020 by Anthony Sunderland



In this article, we will identify some possible causes that may lead to Arcade Mame BIOS, and then I will suggest some possible fixes that can try to solve this problem. MAME (originally abbreviated from Multiple Arcade Machine Emulator) is a free, open source emulator that can be used to recreate the hardware of arcade game systems in software on modern PCs and other platforms. The goal is to preserve the history of the game, preventing the loss or oblivion of old games.


Do you need BIOS for MAME?

Using the ROM BIOS with Mame is an inert process. Mame actively searches for and uses the appropriate BIOS when necessary, without having to do anything. If you are using mame32 / UI, it may be useful to check the BIOS ROMs and game ROMs you want to play to make sure that Mom reports missing files.

I just installed RetroPie on my Raspberry Pi for the first time. During the launch, everything went well (apparently), the update was carried out through the menu (binary update and quick installation).

What is a MAME CHD file?

CHD files are content files that store graphics, sounds, videos, and gameplay for MAME-ROM. CHD files are only required for new MAME games. However, if you have CHD files for your game, you can easily make them compatible with the MAME emulator you are using.

When it was over, several screens appeared on which I was told where to place different BIOS files for different platforms. I find this strange because no instructions tell you anything about the BIOS files (they basically "put the games on a USB stick and plug in, everything should work").
So, I downloaded some PSX games, some Dreamcast games and two MAME games.

September 2020 Update:




When I want to play a game for PSX, the message “BIOS not loaded, low performance expected” is displayed for a short time.
When I try to play a Dreamcast game, an error message appears in the BIOS and I return to EmulationStation. MAME games are not displayed at all. I downloaded the files and unpacked them into folders. Should they be packed differently?

I searched the BIOS on the wiki, but there are only a few references that System X has BIOS Y (or in some cases Y, Z, etc.) without information on where to download it. Why aren't they groupedAre you in RetroPie and / or not accessible in one way or another?

    As in arcade cabinets, there are different shapes and sizes for arcade panels. The variety of control panels largely depends on the number of players that can be supported, the types of games for which they are intended, and the different types of controls used.

Another popular control is the spinner, which can be found at the bottom of the page. The spinner is used ...
