Hi, I don't have any experience with GB Studio, but I just read that it might not support WAV files. Do you know which audio formats this engine reads? I can try to convert them to compatible formats if needed. Thank you for the message!
GB Studio-3.0.3. is capable of running either .mod's and .uge's.
Unfortunately I don't think it's compatible. I don't think it's possible to convert from .wav to .mod or .uge either. I'm sorry about that.
No worries. Whenever I move to Unity I'll know you have this fine tunes!
