The fact is that players usually do not play on their own, but are called from a loop,
most often from the interrupt service loop.
You have CALL 40000 - as far as I remember, the player is initializing? Then it begins
loop, and in it the HALT command. The processor stops and waits for an interrupt. When
In this case, it is in type 1 interrupt processing mode. Therefore, upon arrival of the interruption
it goes to 38H. Those. command CALL 40006 You called once
player, and that's it - the processor doesn't get there anymore. Just try it for fun
remove HALT :).
You need:
1) write some number into register I (this number will be the high byte of the address,
where does the interrupt jump address come from? Low byte is always ff)
For example, if I=EEH, the address to which interrupt control will be transferred
will be taken from addresses EEFFh and EF00h
2) switch the processor to interrupt processing mode 2 (IM 2)
3) the program must be located at a specific address in memory, which
determined in accordance with the number from p1.
The use of interrupts in the book is described very well and in detail.
"Programming in machine codes and assembly language", which is available on
trd.speccy.cz. I highly recommend it, as well as other Inforcom books.

Hello Sinus

Sin> IMHO it is better to compile Mouzons under 49152 (#C000)
Sin> and the program itself under 32768 (#8000)
PT2, ST and PT3 have the same addresses... You can’t say which is better before you can do it,
so on the vernika...
Hello new art
By the way, judging by the playback address (START+6) this is PT2.
IMHO it’s better to compile Mouzons under 49152 (#C000)
and the program itself under 32768 (#8000)

PT2 play - START+6
for PT3 - START+5
for ST it depends on the compiler, I don’t remember exactly, but it seems like START+5
where START - where Mouzon was compiled (usually #C000 or 49152)
And also, attach your music here, otherwise telepaths are on vacation.
Hello Sinus

No problem, Mouzon PT2... There are both Mouzon in the archive, compiled and not.

Nope, in the emulator it says CPU HALTED, in the real one it’s just frozen, if
change the line JR Z,LOOP to JR NZ,LOOP, the effect remains the same. :o

Wait, you said that he had a player... I don’t see the player at point-blank range. On my own
no muzak will be played.
Hello Black1980
Black1980
there is no compiled music.
if you take ProTracker v.2.101 from the Virtual TR-DOS website (http://zx.da.ru)
upload music music AGATA.M (SONG: LOAD) there and compile it (COMPILE SONG)
with the player (you must answer “Y” to the question “Include Player”) under the address (ENTER START
CODE: ) 49152. then answer Y (IS THIS CORRECT Y/N?) and save under the name
AGATA (then it will be saved as AGATA.C) then the following code (for the ALASM assembler)
┌─- code ───
ORG #C000

Hello Sinus
Sin> for ST depends on the compiler, I don’t remember exactly, but it seems like START+5
+6. Starting from pt3, the address was changed to +5.
And one more thing. Players from this very pt3 have one feature - they work glitchy
on im2 in bass. I came across such a disgrace at the dawn of my coding career
activities. pt2&st is ok

Please explain to the teapot what my problem is.
In general, I do the following: I compiled Mouzon, in Alasm I typed the code you
brought it, assemble it, run it, plays :) I go into the debugger, press S (for
save), I enter the name, it sets the address itself #8000, length #0001, unsubscribe,
I'm trying to run the bootloader via BASIC at address 32768, it resets the computer...
What am I doing wrong???
P.S. Don't swear too much, I'm just learning! And I really want it... :)
Hello Black1980
In general, I was able to save it through a debugger with a normal length (156 bytes),
now plays through the BASIC bootloader.... :) But I would really like
find out if possible from the assembler itself (ALASM) save
compiled code, then please tell me. :) THANK YOU ALL SO MUCH! And that's it
After all, the spektrumist community is very friendly... ;)
Hello Black1980
from ALASM code can only be saved in the latest versions with AlCo
perversions, and somehow cunningly through macros.
but in most cases this is not necessary.
I suppose I do this
┌─- code ───
ORG #8000
START
.... your programm ....
LAST
DISPLAY "START=",START
DISPLAY "LENGTH=",LAST-START
└── code ───
and at the end it will output the data to save.
Hello Black1980
Bla> So it turns out that you need to save from the debugger (

Alasm IMHO is not the best option for beginners, better try Zasm (more

Probably there is an abbreviation INCB?
Look at the ASMA body in disasma, all the directives should be visible there.
Hello Vitamin
Vit> +6. This is starting from pt3, the address was changed to +5.
Yeah, and Asm Mouzon Tama I think the initialization was + 11, and the playback was + 14 - but
he is a scoundrel (player) who ate a bunch of bars....

I've never used Alasm, I don't know. I'm used to ksas - assemble, then
save code.

Hello bpm
I’m sitting here deciding which assembler to use (I’m looking for advantages and disadvantages).
It seems convenient in Alasma, but saving it in the debugger or in the tool is not that scary
Everything is much clearer and simpler + saving from the assembler itself. In others if
Honestly, I don’t really want to go in and bother myself. If I can figure it out

Hello, Wlodek
Wlo> And I'm used to GENS4. This does not mean advice at all :) .
In the original, the thing is cool, but with the additives, and even more so, Wlodek’s efforts were not in vain.
GENS4 is very easy to learn, it is clearly known in which addresses it sits, where
the text to be typed is located, where the code is compiled and much more, necessarily
download one of the "Sinclairist's primers":
http://trd.speccy.cz/ section [book] "How to write a game in assembly language"
ALASM is very convenient to work with in terms of text, almost full-fledged text
editor, but with saving the code and addresses where it compiles the program (the text is not
be sure to start with the ORG directive) it took me a long time to figure it out, not to mention
saving object code.
:)
In general, to each his own. Each program is valuable and interesting in its own way (in vain
did you?), so it’s useful to be able to work in all ASMAs (IMHO).

Damn! INCLUDE - text, INSERT - code block!. here [http://zasm.nm.ru] and
user manual and everything, everything. everything... mirror [http://zasm.hut1.ru]
Use it.
--- INSERT directive ---
~~~~~~~~~~~~~~~~
The insert "a:FileName.fnt" directive generates code read from
disk
file named FileName, which can contain arbitrary data (to
approx.
ru, prepared character generator).
The buffer for INSERT is opened only when compiling to disk and is equal to
buffer
INCLUDE. When compiled into memory, the file is simply read into the address
code locations.
