All the same crappy in Siberia, and not
only in winter, but fall ... Stood out the most is the weather
that neither is squalid - A cold wind with rain. On a
thermometer something around 7 - 8. And that's nothing -
Last year all the snow fell on Sept. 20 ...
For half an hour ago, I pinned home with study, did not
escape the cold rain. Sit Now, an article stuffed.
And it's not about coding this article - so,
detail ...

I was honored in August spekovskuyu press and
Coy decided what to add:
1) DEJA VU # 08:
I wrote about a bug in the player from PT3. Gluck
was to hang the player is
Vibrate while processing the command in the channel B
(Editor anything like this was not observed).
Somewhere in a month after the release of the journal
my hands got BestView 2.8, in help'e
to which Ivan Roshchin told about the method to correct this
bug: in player'e at offset # 0A34 # 1A bytes must be replaced
by # 38.
I believe that this method is incorrect,
as while the team does not Vibrate
will be used in the channel B. To make it
everything seems to work, must be replaced by
# 1D!
But that's not all! As a team player
Vibrate is buggy in all channels,
regardless of how fix'a! It turns
(And this is easily seen from the hearing) that
player (or the compiler?) mixed in some places the parameters
of this command.
Can conduct the following experiment.
In the editor, make any "long-playing" a sample and put in a
note to one of the channels with the samples. Then, on a note
Put a team Vibrate (COM 60A1) and Play the pattern. You will
hear intermittent sounds: # 0A frame is sound, 1 frame - No
sound. Now kompilnite all this and Listen outside the editor: 1
frame audio a, # 0A frames - no sound!
For fix'a require such changes
(Player otkompilen at address # C000):
Address There should be
# C86B LD A, (DE) LD A, (DE)
LD (# CBA3), A LD (# CB9B), A
INC DE INC DE
LD A, (DE) LD A, (DE)
INC DE INC DE
LD (# CB9B), A LD (# CBA3), A
LD A, # 8C LD A, # 8C
LD (# CB8A), A LD (# CB8A), A
RET RET
# CA29 LD A, (DE) LD A, (DE)
LD (# CC26), A LD (# CC1E), A
INC DE INC DE
LD A, (DE) LD A, (DE)
INC DE INC DE
LD (# CC1E), A LD (# CC26), A
LD A, # 1A; (# 38) LD A, # 1D
LD (# CC1B), A LD (# CC1B), A
RET RET
# CD35 LD A, (DE) LD A, (DE)
LD (# C6B3), A INC DE
INC DE LD (# C6B8), A
LD A, (DE) LD (# C6A0), A
INC DE LD A, (DE)
LD (# C6B8), A INC DE
LD (# C6A0), A LD (# C6B3), A
XOR A XOR A
LD (# C667), A LD (# C667), A
LD L, A LD L, A
LD H, A LD H, A
LD (# C660), HL LD (# C660), HL
RET RET
After all this, compiled RESISTANCE sounds just like in the
editor.
Yes, one more thing: For some reason initializer does not
return flags teams in the initial state. That is, for example,
plays a your sample with the team Vibrate, and you're in this
time stop playing Mouzon,
initialize it (CALL # C000) and start playing again. So, in
some cases, the first notes of the melody may be played with
nevyklyuchennoy "team Vibrate!
2) ADVENTURER # 09:
Ivan Roshchin boasted of his procedure
translation of character code ("0 ... 9", "A. .. F" and
"A. .. f") in the corresponding HEX-number # 00 -
# 0F. She held this protsedurka 10 bytes, but
less, apparently, do more, you can:
Was: So:
RES 5, A AND # 1F
BIT 6, A SUB # 10
JR NZ, $ +4 JR NC, $ +4
ADD A, # 27 ADD A, # 19
SUB # 37
(10 bytes) (8 bytes)
3) BORN DEAD # 0B:
Therein as to the procedure as
to clear the screen can be a little more podsokratit (as in a
byte):
Was written: It should read:
XOR A XOR A
LD HL, # 5B00 LD HL, # 5B2B
DEC HL LD (HL), A
LD (HL), A OR (HL)
OR (HL) JR NZ, $ -4
JR NZ, $ -3
Only now it is still as it cleans and
part of the buffer the printer ...

Finally - a little announcement:
1) RUSH # 1 was little article about how the sounds
done (nose:). It so happened that
the week before reading this article, I
itch to dealing with this trial
lemoy. From the article, I realized that there is any
di which are interested, therefore, decided
share the results of their own
research.
The results represent a simple
tenky editor of samples. Editor to
fairly simple, work with the disk generally speaking
slit will be Busick. Nevertheless, emergency medical service
ly possible to do decent. In general,
wait for the next issue, but so far only
