Continuiamo il viaggio iniziato lo scorso anno nel magico mondo della moderna programmazione del Commodore 64. La scena italiana e romana è molto attiva. Dopo una brevissima introduzione sugli sprite in generale, il mitico Andrea Pompili, autore dello sparattutto Catalypse pubblicato da Genias nel 1992, ci spiegherà la tecnica dello sprite multiplexing, utilizzata per superare il noto limite degli 8 sprite contemporanei a schermo, applicata al suo gioco.

Editor's Notes
- Il biscottone
- CPU VIC SID CIA sono tutti memory mapped
- La Color RAM è organizzata come memoria 1024*4bit (nibble).
- 47 registri MEMORY MAPPED
- VIC indirizza a 14 bit -> 16k. i 64k vengono partizionati in 4 blocchi da 16k La Color RAM la vede sepre allo stesso punto indipendentemente dal banco Tutta la roba di grafica va dentro i 16k che VIC vede in quel momento. Occhio alla char rom. Non ci si può scrivere dentro, sono locazioni blindate.
- TEXT MONO E MULTI COLOR
- I banchi del VIC II
