Hello all!
Great news: our Oric has PT3 player!
Thanks to French Touch, who shared his incredible work, now everyone can create new demos, add PT3 music to games and enjoy these high quality tunes.
Visit French Touch youtube channel to see his demos.
There you can find zipped sources and some DSKready to play. (I attach below the same ZIP just to mirror this precioussss;)).
Fun detail is that I was following the work of deater78 on comp.sys.apple2, planing to port his code for Oric... and surprise, surprise - French Touch come with his master piece - ready to use PT3 player!!!
Merci beaucoup, French Touch!

Re: AY music: PT3 player!
I have just downloaded and tested it and I am quite impressed!!!
At least a pro-tracker for our Oric which is compatible with Vortex... is this true?
I'll give a look at the size and CPU usage (which I guess will be quite high), but it is indeed a great job. And excelent news for our community.

Re: AY music: PT3 player!
Very cool
The code is a bit confusing, is that actually a Z80 emulator???
to anyone trying to optimize it: There's a lot of self modified code that is not obvious at first glance.
Like for example:
The code is a bit confusing, is that actually a Z80 emulator???
Code: Select all
; "registers" Z80
; A = A
; F = flags
z80_A .dsb 1 ; save A
z80_C .dsb 1
z80_B .dsb 1
z80_E .dsb 1
z80_D .dsb 1
z80_L .dsb 1
z80_H .dsb 1
z80_IX .dsb 2
z80_AP .dsb 1 ; save A'
Like for example:
Code: Select all
PrSlide
LDA #$AC <-- Put AC in A
STA z80_E
STA (z80_IX),Y
INY
LDA #$AC <-- Look mum, an optimization, I can just remove that one!
STA z80_D
STA (z80_IX),Y
(...)
PTDECOD
LDY #Note
LDA (z80_IX),Y
STA PrNote+1
LDY #CrTnSl
LDA (z80_IX),Y
STA PrSlide+1 <-- Not so fast! Patches the first one!
INY
LDA (z80_IX),Y
STA PrSlide+8 <-- Not so fast! Patches the second one!
