# 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
|
|
|
