| # WonderSwan
 | |
| 
 | |
| a handheld console released only in Japan by Bandai, designed by the same people behind Game Boy and Virtual Boy.
 | |
| for this reason it has lots of similar elements from those two systems in the sound department.
 | |
| 
 | |
| it has 4 wavetable channels. some of them have additional capabilities:
 | |
| - the second channel could play samples
 | |
| - the third one has hardware sweep
 | |
| - the fourth one also does noise
 | |
| 
 | |
