The editor saves tunes (C=+E) with 2 bugs:
1) JMP 1000/1003 aren't correct, they need to be replaced with
1000 4C EC 10 JMP $10EC
1003 4C A6 11 JMP $11A6
original jmp at $1000 points to $1007 which is the test irq player installer.
The correct addresses are derived from that.
2) relocator fails to change one table address. When saving to $1000 you have
158A BC 71 10 LDY $1071,X
158D 18 CLC
158E B9 80 2A LDA $2A80,Y << this is always wrong
1591 7D 57 10 ADC $1057,X
Comparing with the internal editor's player, the correct pointer is $196b for
a tune at $1000, or loadaddr+$96b.
158E B9 6b 19 LDA $196b,Y
Final note, for multiple subtunes, it expects to read the selected subtune from
$1006 (loadaddr+6 that is) so an init must be
LDA #subtune (0-E)
STA $1006
JMP $1000 (or $11a6 if you don't patch the JMPs at $1000)
.end.
