Got my sega turbo working for the most part. 2 things 1 my cars are stretched out but rest of graphics seem fine. 2 all sounds seem to work except when i crash there isnt any sound. Any suggestions thanks
The graphics size is controlled by trim adjustment pots on the PROM board. If I remember right the sounds are generated with discreet components and mixed together. The manual for Turbo is very detailed in how it breaks down those circuits, basically sound by sound.
