Ok...MD 2 and sound issues? A friend of my claims that Tänzer have sound issues on his MD2. Low volume and later totally disappears.
Other games don't exhibit this, he says.

Guess I need to buy one, any suggestions regarding this?

Did you try to send him a version with the Z80 HALT flag turned ON ? We normally expect sound issues first when Z80 memory access cycle is shortened.

Yes, he tried the latest version that has the flag on.
He didn't remember but he thought that he didn't have any sound at all in an earlier version.

I just pushed some changes in SGDK github repository, i added a new flag : HALT_Z80_ON_IO (in config.h as well). This time it allows to force Z80 interrupt on IO access. That is something which can lead to issues on some specific MD models (i never meet any of them but still safer to have that). You can try to rebuild the lib (enabling that flag), recompile your game and send it to your friend :)
By the way, are you doing some low level controller accesses in your code ? If that's the case you have to take care of disabling Z80 too.

Would probably be faster that way :D
Unfortunately i don't own any MD2 anymore but i still own a Sega CDX (which should behave closely i think).

So, the issue seems to be that when I plug in the red (right audio) cable into the scart connector the sound gets really strange.
Not having this connected (only video and left audio cables) everything seems to work just great. :shock:
What am I missing here? Any suggestions?

Edit: Same thing with every game I test with so this is a non-issue. So sorry for taking up your time. :)

Seeing your first part of your post i could definitely said it isn't a game issue ;) i guess there is something broken in the sound mixing circuit..

Huh, yeah, that's very definitely broken hardware o.o;

Things that could be broken:
- right audio cable is broken, sending garbage
- audio mixing circuit is broken, causing garbage to go on that cable
- TV stereo circuit is broken, causing it to misbehave when getting stereo from that connection

It's very definitely not a software issue tho. As far as games are aware, output is always stereo, they can't behave different when connected as mono.

Had a final testing-session yesterday at work. They found one bug and I have now fixed that and the ROM is sent off for manufacturing. \o/

Thanks you all so much for the support! Could not have done any of this without it!

(no I need to take care of the OST, then I can start slacking again...)

Congratulations !!
Can we know how many carts did you ordered to the manufacturer and if you plan to do several batch ?
I'm sure that with good communication you can sell easily more than 200 copies =)

Thanks!
226 carts were ordered. And I've arranged for the manufacturer to take control of the game after this.
More news about that when I have it. :)

Wait, game is already done?

I'm with Stef here, I'm pretty sure you could have gotten more orders with better communication, honestly it feels as if anybody who wasn't actively checking the kickstarter page didn't hear much about what was going on (I didn't even think it was that close to done already).
