You should create a config file for SCF, where you define CODE, DATA and GFX blocks. The GFX blocks will give you a graphical impression of the data. Here is a part of River Raid: .byte $2A ; | X X X | $FCC1 .byte $3E ; | XXXXX | $FCC2 .byte $1C ; | XXX | $FCC3 .byte $08 ; | X | $FCC4 .byte $49 ; | X X X| $FCC5 .byte $6B ; | XX X XX| $FCC6 .byte $7F ; | XXXXXXX| $FCC7 .byte $7F ; | XXXXXXX| $FCC8 .byte $3E ; | XXXXX | $FCC9 .byte $1C ; | XXX | $FCCA .byte $08 ; | X | $FCCB .byte $08 ; | X | $FCCC .byte $08 ; | X | $FCCD My River Raid config file looks like this: GFX FB00 FBB6 GFX FBEF FDB0 GFX FE00 FEFF GFX FFB3 FFD2 DATA FBB7 FBD4 DATA FDB1 FDD7 DATA FDF6 FDFF DATA FF23 FF5A DATA FFF7 FFFF So, the first step is to start diStella with the -i option, then you have to find out where the data, code and graphics are. Then create a config file, which you can improve step by step.
