Interesting, BiFi said it's not present in 2.8.2.

Aha: he says it only happens if you use SCC+ as romtype for a ROM cartridge. Not if you actually emulate an SCC+ device.
(This ROM type is for the games of the Konami Game Collection hacked into a ROM.)

In other words: there's no bug. Just a hack, which you shouldn't use for other things than the Konami Game Collection ROM hacks.

Apparently the SCC slot is not detected correctly...
I'm using this snippet, maybe GuillianSeed could say faster than me what does not go with it when used with his MegaFlashRom scc+sd

In which slot is detected?
If you send me the ROM I'd have a look at it.

The rutine seems fine, but I would change this:

	jr z,testreg      ; no -> repeat mirror-test
	ld a,b
	ld (#9000),a      ; restore value on 9000h

That would select an undefined bank. It is better to leave bank #3F or manually select bank 3 (default bank).

Also, I agree Manuel: don't work around emulator bugs.

Thanks for willing to test!

I wrote functions to increment the slotID for searches.
get incslt decslt clslt eslt from slottest.s
see the slotcounting in the slotviewer.
with slotfunctions, things get soo much more easy.

@frederic.markus
What is your configuration, which machine do you use and which version of the megaflashrom scc+SD?

With Guillian we have found that openmsx 0.11.0 and openmsx 0.10.2 (beta) differ in the way they emulate the megaflashrom scc+sd.
Only on openmsx 0.11.0 the problem between uridium cart and the megaflashrom scc+sd appears.
On openmsx 0.10.2 (beta) the cart and the megaflashrom scc+sd work together perfectly.
What has changed in the emulation of this device between the two versions of the emulator?

Guillian was using openmsx 0.10.2-174 : on it the Uridium cart and megaflashrom scc+sd works without problems
On openmsx 0.11.0 the same configuration fails with the same symptoms reported by frederic.markus
