Shiru has released the long awaited update of 1tracker. Version 0.16 includes two new, quite unique 2-channel ZX Spectrum beeper engines, both of which were previously unavailable in editors. One is from the 1990 game Earth Shaker. It was disassembled by Oleg Origin last year. The other one comes from a little PWM experiment I did a while ago. Also, there were some internal changes, which will hopefully increase stability.
Download is here.
