Instrumentarium Remix (Pokey tune with unusual instruments)

Recommended Posts

I decided to release some files I used to compose the Instrumentarium tune. I'd call it 'source' files.

As a reminder, see this link: http://www.atariage.com/forums/topic/149261-a-new-pokey-tune-unusual-instruments/

Some description of how I did it:
-Patch RMT with custom notation tables (sawtooth, 1.79mhz distortion2, distortion guitar) : Patch version 3
-Compose tune in RMT (Patch 3)
-Compute another custom notation table for the 'clarinet' instrument: insert values in a Table of Pitches in 4 instruments
-When finished, export the file to .xex
-Open .xex in Hex editor and insert/replace some stuff (see below: 'Bypass hack')
-Save again as the final .xex
-Make .atr

Description of the bypass hack:

Step 1:

Find: 20 18 39 (means JSR $3918
Replace by: 20 00 20 (means JSR $2000 : the bypass code)

Step 2: Insert an extra data module:

Start of file was:
FF FF 82 31 58 39 ....

Insert new data between 2nd and 3rd byte:
FF FF {} 82 31 58 39 ....

This becomes:
00 20 11 20 A2 03 A5 D1 F0 04 C9 FC D0 02 A2 8B 8E 0F D2 4C 18 39 (the inserted line: 18 bytes)
82 31 58 39

The insert means:
[code]00 20 11 20 = new data module (of 18 bytes) from $2000 to $2011
A2 03 LDX #$03 ; Default value to be stored into SKCTL ($D20F)
A5 D1 LDA $D1 ; RMT zeropage register : Which songline number is playing?
F0 04 BEQ #$04 ; Skip next 2 instructions if songline# value = 0 (corresponds to line $19)
C9 FC CMP #$FC ; Check whether songline# value = 252 (corresponds to line $18)
D0 02 BNE #$02 ; Skip next instruction if songline# value <> 252
A2 8B LDX #$8B ; Value to activate 2-tone-filter (in songline $18 & $19)
8E 0F D2 STX $D20F ; Store value of $03 or $8B into SKCTL
4C 18 39 JMP $3918 ; Continu from bypass[/code]

In the files I included:
-RMT (Patch 3) tool
-Final .xex & .atr files of the tune
-Original RMT file of 'instrumentarium remix 1'
-Textfile with custom notation table I computed for the 'clarinet'

Any questions? Technical or other? Feel free to ask.

Have fun. Edited by analmux
