    Using 32-cell ( instead of 40-cell ) mode drops the maximum number of sprites per scanline from 20 to 16 ( and the total from 80 to 64 ) .. so that doesn't exactly help.

    Never mind .. the seller was kind enough to send me some pictures before shipping it to the buyer and it turned out it was simply a "COMPLEX 32 IN 1" cartridge with a ( purposely ) deceiving label.

    Wasn't even aware that the NTSC versions had a different soundtrack :o

    Kind of sounds like the NTSC version is YMF292 based ( while the PAL version uses Redbook Audio )? Can anyone confirm?
