Hello, in this post, i share with you, a 6.01 gb bios pack, i just, found some bios on the internet, and decide to spare people time to search for bios and download them, i got pretty much of all useful files to have, for the most known consoles, and some arcade files to use in emulators like MAME, or DEMUL, here is the file link (updated)
but, just a quick reminder, and its something that i can`t help, for people who want to emulate arcade games, there will be some problems, you will need a few more files, for this, you will need to search online, i dont play a lot of arcade games, but if you want just contact me to add some more files to the archive, and this counts for every emulator, just to help more people.
What I'm wanting to do is somehow run BIOS-only OSes on computers that do not support BIOS booting or CSM. Does there exist an efi application that I can chainload that can act as some kind of emulator for legacy BIOS?
A "BIOS emulator" would mostly be a full BIOS implementation, minus the motherboard-specific hardware initialization code. The one that's typically used in such situations is SeaBIOS, which is used e.g. on machines that use Coreboot firmware (dual-booting Chromebooks and such) in a very similar way as you're asking for UEFI.
Why is it not included in the emulator? And why do some emulators, like those emulating Playstation or Playstation 2 need a BIOS and some, like N64 emulators, do not? Is it necessary to pirate the BIOS? Or is there a legitimate source?
So, for anything past Windows 7 (and as seen an emulator for BIOS 10h is needed in some setups) it is a non-problem (as the OS will be UEFI compliant) for all the previous OSes, a VM or similar will soon be needed on newer UEFI only machines.
BIOS dumps contain intellectual property therefore it is illegal to distribute them without consent from the manufacturer. My guess is that most developers do not want to include any intellectual property in their emulators. It is the same reason why you won't find emulators being distributed with game ROMs.
This directory contains my research into the bios itself. It has rom files both downloaded from Asus's website above and ripped from my motherboard. The bin files came from the mmtool and the report.txt is a cpu-z report file with personally identifying information removed.
I want to learn how it runs so i can possibly write my own OROM file and or add UEFI support to the BIOS. This is a legacy bios which asus seems to have stopped supporting so no more updates will come out for it.
When ever I try to run an emulator I see this error"Intel HAXM is required to run this avd/dev/KVM is not found.Enable VT-x in your BIOS security setting, ensure that your Linux distro has working KVM module'
In order to emulate some home consoles (Playstation 1/2, Sega Saturn/CD/32x, etc.) a dump of the system's BIOS is required to emulate the console. Out of the Nintendo 64 emulators I have found online, none require the BIOS for ROM playback. How can N64 emulators work without the system BIOS? Is this because of the way the Nintendo 64 system was architected, or choices made by the author of the emulator?
I realize this is probably done so as to avoid the million and one variations of hardware and corresponding bios that go with it, but I was just curious if it was even possible to get an actual bios to work..
Granted, the mobo specific registers & special vendor specific bios codes won't work, but I wouldn't think it would crash bochs... At most I just figured it wouldn't work, ie, the bios code would hit some kind of abort/endless loop code since the POST was probably detected as failed..
While I agree that using a real BIOS looks like it doesn't work, I have managed to find a video bios which does work - my old SIS6326 PCI card had a .rom file for download off the website, and I tried it and it worked! Obviously it didn't do much though because it wasn't running on the proper hardware - the 6326 card isn't emulated - but DOS things worked fine, if i remember correctly
Exactly what I was looking to see.. When I tried it, (this was 6 months ago), the bios crashed hard..
I might try some others to see if I can get it to work, would be more "authentic" for me.. :)
If nothing else, it makes the "cool" factor more real..
It does not show up in the MAME menu. The aforementioned "mame.ini" file is not modified within the emulator. It typically resides in the same folder as the "a7800.exe" file, and can be opened and modified utilizing a simple application such as Notepad.
1. A7800 has been downloaded and files unzipped to a clean folder. BIOS file(s) were also downloaded and placed in a "bios" sub-folder. The folder should appear similar to the following capture:
By utilizing the merged BIOS file from archive.org [Linked to previously under "Quick and easy portable install for Windows:], all that is required for every 7800 system and configuration to work, is placing the "bios" folder which contains a merged "a7800.zip" BIOS ROM set, as a subfolder under where the A7800 emulator was installed.
A7800 emulator supports both zipped or unzipped BIOS file sets. Zipped is recommended (And illustrated above), as it is easier to manage and less steps to accomplish the same goal. If one chooses to unzip the "a7800.zip" BIOS file archive, the individual files should be stored inside a "a7800" subfolder within the "bios" folder.
There have been a number of contributors to get Atari 7800 emulation to where it is today under A7800. In recent years, it has been RevEng's contributions which are the most dominant and essential in bringing the hardware accuracy enjoyed under the emulator. His labor of love is very much appreciated.
The screen you are getting is because the program cannot find the bios .... might I suggest a complete redo of the files...delete the current folder...then create a folder (call it what you want) then extract all the files into that folder. then Find the A7800.exe file and open it..it should work.
Based on your earlier hint I went and chosen a different path: installed AEL from a zip file and the desired emulators: snes9x2010 and pcsx-rearmed from standard LE/Kodi repos, then proceeded to define the launchers that called RetroPlayer (at least to my still shaky understanding that's AEL/RetroPlayer approach that none of your 3 alternatives cover).
Note about the bioses: copied over all the files I had on RetroPie, don't know if the same ones are expected here. Maybe it's looking for slightly different names, or different case...is there a way to check retroarch is finding the expected ones?
And in regards to the bios, as long as you have not changed any configurations within retroarch you have placed them in the right place but you can check where retroarch is looking for them by looking for directories within the retroarch program once in directories the top one should be system/bios and it should point to /storage/emulators/bios.
Welcome to emuparadise.org's BIOS section. Over here, we have a great selection of BIOS files for people who are trying to emulate and need a BIOS to get through. The BIOS's come in handy when you need to use one with an emulator, so you can look to this section for all your BIOS needs!! (Note: They also come in VERY handy for development purposes!)
I went to manage > emulators and deleted RetroArch from there, and then reinstalled it from manage > retroarch > install, and it seemed to install fine, but now all my games that were using retroarch without any issue don't load and say that the emulator cannot be found.
If i manually edit a game (such as a PS1 game) the emulator field is blank (despite manage > emulation > retroarch showing as associated with PS1) but if select RetroArch for that field and try and play the game then nothing happens. Literally selecting play means nothing happens.
Not sure that what you want to do is actually possible. The new feature is for new imports, you already have your systems setup, As for changing the emulator that's easy. click a game in a platform, then CTRL-A to highlight them all, right click one, edit, emulators, pick the emulator you want to use from the list.
I have not used the new RA installer since I have had it set up for years. However, I believe the prompt will only show up if you do not have the bios already inside Retroarch folders. In your case was the bios already in the correct RA folder?
Just setting the platform name is the associated platform does not link games already in a library to Retroarch if those games are already using another emulator. You need to select existing games (you can select one, several, or all) and then bulk edit them and change the emulator to RA. This will set it as the default emulator for existing games. Also to note, since you deleted Retroarch it removed RA from all those games.
