Does Altered Beast (Japan) work on a EURO PAL Mega Drive I/II?...

I just got a mint Japanese copy of Altered Beast Cart, for the SEGA Mega Drive (Japanese)
I have a EURO PAL SEGA MEGA Drive I (Bulky model) console and a EURO PAL Mega Drive II (Smaller model).
All my Japanese carts work perfectly on both consoles, either by directly inserting the carts into the slot (I have trimmed them out) or by using a Universal Adaptor cart. (Nitro Adaptor 2 for PAL & NTSC MD)

But when I insert Altered Beast (JPN) cart, the typical SEGA quote comes up:

ďProduced By or Under License From SEGA Enterprises LTDĒ

Then a Black screen and then nothingÖ

Same thing happens on both MegaDrives, even when I used the Universal Adaptor.

The cart is fairly mint and does not look damaged, but could it be that this specific cart has a region lock-out? Altered Beast (JPN) was one of the 1st Mega Drive games (1988) so itís doubtful.

So does anybody have this specific Japanese Altered Beast working on his EURO PAL SEGA Mega Drive I or II?
Is this a region-lock preventing it from working, or should I assume that this is simply a defective cart?

Please any feed-back will be highly appreciated, because if anyone of you has a working Japanese Altered Beast on a Euro Mega Drive, then mine would be a defective cart, so Iíll just send it back.

Anyway, after having modded my Saturn, PS-1, PS-2 & X-Box my self, Iím considering doing a 50/60HZ and country switch mod to one of my two MEGA Drives.
That should bring some light to the problem.

I found these instructions:

MD Model I

MD Model II

Are these instructions ok by the way?
I wouldnít want to mess up my consoles?

I think Iíll try the Model I 1st, it looks very easy. Unless there is a reason I should do my Model II instead?

Any one has better diagrams/info on how to mod a 50/60HZ & country switch on MD Model I & II by the way?

I also went ahead and tried the 3 known Altered Beast good Rom dumps:

Altered Beast (UE) (REV02) [!].zip
Juu-Ou-Ki (J) (REV00) [c][!].zip
Juu-Ou-Ki (J) (REV01) [!].zip

In Gens & Kega emulators set to PAL region under WinXP.
All three worked perfectly in 50HZ & did not freeze like my cart after the logo, so it might be a defective cart after all.
But I canít be certain that my cart is in fact any of the 3 Rom dumps that I tried?
Only way to be sure is if could dump the Rom to my computer (using the Sega CD Transfer Suite tool from here: and try it on the Emu.
But I would need a SEGA CD to connect to my pc via parallel cable and I donít have SEGA MEGA CD at the moment.


Any help will be highly appreciated?
