Ghettoblaster is a musical sound effect in To be on Top.
The song uses the bass from the the 15th inspiration in F minor with all-new drums and a chord.
On both platforms, it is the only song without samples, since the smooth scrolling requires the CPU time; even the drums rely solely on the respective sound chip itself.
To be on Top (C64)
Whenever a skater passes by with his ghettoblaster, the song plays twice, interrupted only by another sound.
The driver outputs the song to the SID chip and was recorded doing so within VICE 3.2 with the model 6581 (ReSID) and the filter bias 180, although it is unconfirmed how close it is to what the arranger heard. It is track 14 in the rip.
To be on Top (AST)
Hippel transposed to A minor, wrote another unique drum pattern, created 5 more variations, added the accomp of the 15th inspiration to 3 of them and composed an all-new melody for the 6th one. Comically, 2 variations also play when the old woman (likely without ghettoblaster) passes by. Also, the music loops until the passer-by leaves.
The driver outputs the song to the YM2149F chip and was recorded doing so within Steem SSE 3.9.4.
