I am playing Sonyc on my MSX2+ with MSX-Music and everthing works perfect.

But when I use my new Moonsound and play the game the background in not scrolling perfect.

Did somebody has the same problems.

I use a modified Sony HB-F700P, 1024 kb, MSX2+.

It is explained in the manual that comes along: when using OPL4, a turboR computer is recommended, because of the latency of the Wave driver. Forcing the game to 50Hz (iirc pressing '5' in the main screen, dunno for sure) will help a little bit, but I don't know whether it's enough.

It also works fine with 7.16Mhz

latency? pfff, you mean a slow driver don't ya? (latency kix in when combining 2 sources of audio to run at the same time. e.g. a multitrack recorder playing your tracks while recording another one.)

My case is worse. I have a 512KB WSX but can`t even run it. The game freezes after choosing the dificulty level (Easy or Normal). Any tips?

Does it have only the 512kB mapper? Or did those computers also have 64kB non-mapped RAM? If so, that could be the cause... Does Sonyc allow the use of DOS2? If so, that would prolly solve it...

As far as I know, the 512kB is mapped RAM. Also, Sonyc works on DOS2, and doesn't read any mapper register (#FC-#FF)
Right now, I don't any idea where is the problem for not running in a WSX. Anyone with the same problem?

I know the 512kB is mapped, but some MSX2+ models had 64kB of unmapped(?) RAM as their primary memory. At least, I think it's unmapped. Could've been 64kB mapped RAM too, but either case 64kB < 128kB, which could mean trouble if the game doesn't search for alternative mappers. Anyhoo, since DOS2 would handle all that stuff, running the game in DOS2 mode would solve that...

Well, Sonyc works on DOS2, but does NOT use DOS2 functions ^^!

It can't not use them, cause then it wouldn't work... Well, unless they kill DOS2 mapper-support alltogether, in which case it doesn't really work under DOS2 but merely tolerates it... Anyhoo, it either uses DOS2 routines or direct memory switching, in case of the latter it won't work on the WSX without modifications...

Well, I tried it also on BlueMSX (on several versions) and it didn`t work (in fact, it shows the same problem). I am thinking that it may be de disk image, but I downloaded it from its official website.

Also, WSX only has mapped memory, even when it is 64KB.
