PSID RIP of TUNES

If you today want to listen to your preffered tune games/demo using your PC, you can do these:
  1. take a C64 emulator and then run the games in his original format
  2. take a PSID file containing the tune and listen it with a sidplayer
A PSID file is a special file containing the code that a tune must execute like in the C64 for producing the sound, with some extra hack for making sample music.

I have creating some rips, essentially because this is a simple way to understand how a music is made.

Arrival of the queen of Sheba
Andrew Colin
1983 Commodore
This is a demo tune described in Appendix A of the Introduction to Basic  part 2 book. It uses 3 voices controlled by machine code, while all the data are putted in a Basic Program. However it uses a complete 8 octave frequency map for the notes.

I rip this tune essentially because my first tune use the same engine, so I know it very well.
It is very good sid music that use little of the SID functions, but with a wonderful result for a 1983 tune.


Testcard
Andew Colin
1982 Commodore
This is a demo tune used in the Introduction to Basic part 1 book. It uses 2/3 voices controlled by machine code and Basic too. However the engine is just a previous step of the one used in Sheba.

This is probably one of the first C64 demo, with sound and animation. The sound is quite simple.

1983 Commodore
The first game I play with my C64. The engine use the IRQ for music and NMI for changing the music when a screen is passed. Voices 1 and 2 are for music, while voice 3 are for sound effect.  It uses a table of 1 octave frequencies, but you choose the octave you want to play.
       
Dig Dug
?
1984 Datasoft
A very nice platform game. The music is game sensitive: it changes according with your actions.
The engine don't have frequency table, but the pattern is a sequence of  instructions to perform: set ADSL, set frequency...,


Android 2
?
1983 Ocean
A great Oxygen 4 of Jean Michel Jarre is played by this game. You may change the music level by pressing some keys (in the rip there's the default middle value). The engine has a sequence of instructions to performe (like set frequency...), but patterns are even present.

The rip is not good as I want: the compiled source dosn't sound in C64 emulator; only PSID file are play correctly by sidplayer.


Petch
?
1983 Colosoftware
Popcorn by Hot Butter is the main theme of this game. The music is made only by one voice. Tables of frequencies/durations compose the notes to play.

Empire
?
1985 Firebird
A game with music that changes according to the screens. Only 2 voices for the music, plus one for the sound effects. The rip seems me not so clean as I expected.


Telengard
?
1983 Havalon Hill
This is a machine code conversion in RSID of a BASIC rip. The conversion cannot be as in BASIC but you should be able to listen to it with a good feeling.

Sword of fargoal
Jeff McCord
1983 Epyx
This is a machine code conversion in RSID of a BASIC rip. There is also a try to emulate some RND instructions used in BASIC.

Silly 64
?
1983 Silly Software
This is a machine code conversion in RSID of a BASIC demo. The conversion cannot be as in BASIC but you should be able to listen to it with a good feeling.
