what about the original Mega-ED? is it supported?
Mega-ed v1 support stopped few years ago and i have no any plans to work over updates for v1. Also this update will not fit in mega-v1, according to my calculations, because v1 used more fpga resources than v2. At the moment fpga used on 96% on mega-v2

well that's sad news for obvious reasons since the original mega-ed was a premium cart ... but if it does not fit then nothing to do really

I just finished Necronomfive's FM core integration. Here is test OS build: http://krikzz.com/pub/rc/MEGAOS-V3.04-RC1.zip
Aside of FM supports, it supports sms bios loading. Details about bios function in sms-bios-readme.txt

Wow, that was fast! 8)

I'm reading about the different SMS bios. It seems like the Uncommon BIOS v2.0 might be the best choice? If not, what exact bios would be the best choice for compatibility? Or are the checks overridden by the MED anyways?

Also, in Krikzz's video, I see a CDBIOS.BIN in the Mega folder as well. Is that where we put a CD bios to use the "run cd" option?

There is zero way make sms bios loading working with x3 and x5 Everdrives?

Those cheaper models have less expensive components, which also means the components (FPGA) are not as powerful.  He doesn't feel it can be done.

Terrific news! I don't have the right hardware to support this right now since my EverDrive is an original EverDrive-MD, but it's a good reason to upgrade in the future. I have a Master System and an FM upgrade board, but have never gotten around to installing it...

I have an FM upgraded SMS as well!  Ha ha ha, had someone else install it.  I will say that SMS Bios is probably not going to fix incompatible SMS games on the Genesis.  Those do not work because SEGA removed the VDP modes they require, same as SG-1000, from the Genesis/MegaDrive.

This is dump of bios from my cd unit, cart makes it when boot cd from internal bios

Is it possible to implement the sms bios support into x3 and x5 Mega Everdrives?

No, x3 and X5 not supports FPGA core update.

The OS option to enable/disable YM2413 also controls whether an SMS bios is loaded it seems. Will it be possible to use a real SMS bios, but without FM sound?

It seems that after adding this the in-game menu no longer works on my X7. The option is OFF and it's greyed out in the options menu.

e: after using the files Krikzz posted earlier, it works again. The game music volume is lower on the SMS games that use the FM sound than when I was using the original file in the OP.

In game menu still works fine for me. Do you have a 32X attached?

Also, are you sure that you have an X7 (or V2)? It's the only Mega EverDrive with IGM support.

Bios and fm sound functions works independently

Yes, I have the V2, and I was using the FM sound file successfully when testing it yesterday. I just noticed today that the in-game menu also stopped working. No 32x here either.

You used OS 3.04 RC1 or Necronomfive's RBF file?

I used Necronomfive's RBF file and in-game menu did not work with it. After I used the file you posted (with the integrated OS) it started working again. (but like I said the volume is lower than it was when I used the RBF file.)

Necronomfive's RBF not supports save states, it will work only on official OS update
