8b intro for ZX Spectrum 48k
Code: Busy soft
Create: 20.01.2025
Release: LoveByte 2025
Simple 8-byte effect with filling whole screen
and producing sound on EAR and AY-3-8912.
The 8 bytes of code presents:
- Monochromatic strips in paper
- Multicolor strips in border
- One bit noise sound on EAR
- Stereo noise sound on AY
The intro can run correctly on original 128k/+2 only.
There is no paper filling on ZX Spectrum 48k.
Unfortunatelly, intro crashes on +2A/+3 and
all models with enhanced memory (more than 128k).
Anyway, you can disable any bank switching
then intro runs by the same way as on ZX 48k.
