FWIW I had a spare dead cart lying around that I was able to successfully burn a SuperBIOS USA NoCD BIOS to. Interestingly, I had to write it twice for it to work after erasing it with my programmer (Xgecu T4
. The addresses all read blank (FFFF) when I first programmed it which was odd considering I erased the chip beforehand. Writing the same BIOS a second time & reading it afterward to verify it burned got me back in business.
“Look ma…no CD!!!”

From the pack below?
Too bad I don't have any custom carts here.
I read the chip back twice, so it wasn't a bad program.

If you got them from here, they should be good. Only one byte change.

Just bear in mind that one is for custom SH2 and the other for standard SH2.

Cps3 noob here so apologies in advance.
Picked up a cps3 board for a reasonable price I think. (€370 all in I thought was good). But it was originally a jojo so only has 5x simms and didn't come with a CD drive or cart.
I have a darksoft ultra bios cart (CD required version) and a blue scsi with db25 connector I use with x68000 (not the 50 pin one on the cps3 board).
Powering it on with the cart plugged in I get an error about "not enough memory". Holding p1 start at boot up does nothing.
1. I'm reading the older super bios cart needed 6x simms. Is it the same for ultra bios carts?
2. If so, then given most cps3 games came with just 5x simms, where did everyone get their extra 128k simm #6 from?
3. Can I use a db25 to 50 pin adapter for the bluescsi?
4. If I get this working and flash a new game, is there a way to convert ultra bios "CD required" cart to a "no CD" version and vice-versa? (So I can disconnect the bluescsi to use with the x68000).
5. Last but not least: assuming jojo is flashed to these simms I have now, is there anything I can do to get it running as-is with what I currently have?
Thank you!

Yes
Ebay and also I made some repro Simms some years ago.
I'm not sure. I use a SCSI2SD.
The only way is by reflashing the Flash chip on the cartridge. All the files needed are here in the forum.
Not with my BIOS, I'm afraid.
Thank you darksoft!
I will look for a 128 simm to buy and keep a look out for ultrasimm restock. (Edit: Got this "converted" 128m simm from sheep_nova on ebay https://www.ebay.ie/itm/276304028450 )
Will try this db25 to 50 adapter and post if it works with bluescsi:
https://itead.cc/product/scsi2-50pin-to-scsi1-db25-adapter/
It seems flashing the cart bios involves physical desoldering with hot air, writing with a programmer and re-soldering to the card pcb. If so, I think I'll leave it as "cd required" for now and change if I get ultrasimms in future.

I use a BlueSCSI and they work correctly with the CPS3 - but mine are the 50 pin variant
I have not tried with the 25 pin variant and an adapter but I suspect it won’t work because it is emulating and the CPS3 is expecting a 50 pin device

Good info. Thanks @xodaraP
It is also possible to expand the Bios and have CD and NO CD in a single cartridge.

What sorcery is this?
Assuming this isn't something that will be publicly shared on how to do?
I don't know how.
looks like bankswitching. pull down (or up?) resistor and you can see a switch cutout in the cartridge case.
if there's a larger, pin compatible flash memory it seems like it'd be pretty straightforward.
