Summary0001196: Turrican 2: Second Joypad Button don`t work, if i start the game from Floppy it
DescriptionInstall: Turrican 2 (Factor 5/Rainbow Arts) http://whdload.de/games/Turrican2.html
GameVersion: english,pal
SlaveVersion: Newest

Second Joypad Button don`t work, if i start the game from Floppy it works.
I try 3 Joypad`s. The second button is for the Wappon that goes from
the Middle to the left and to the right and destroy all (small) enemys on
the Screen. You have 3 of this on Game start.
The other Wappon that comes if i press both Buttons on the
same time don`t work too. This is this heavy one that is good for big
enemys. From this you have only one/Life.

is that problem still present with the latest slave/install version?

Yes, its still with the "newest" downloadable version from www.whdload.de

The only idea I have is that it's connected to some custom registers init.
Will try to check this.

I've tried 'Honey Bee' and 'tecnoplus' pads with disk and cdtv version of turrican2, second button is working in all of them.
What joypad are you trying?
Special QuitKey set?

My Version have Disk.1 1.069.768 Bytes and none Disk.2 seems that
version available free for download.

The Jopads are connected like a Mouse,
Pin 5 to GND
Pin 6 to GND
Pin 9 to GND

Not such CD32 Serial stuff.

One of them have only 2 Firebuttons.
I remember for the 2. and 3. Fire Button you must write
to the CC in front of every read out the follow:

POKEB &hDFF034, (PEEKB(&hDFF016) OR &b11110000)

That means readout 0xDFF016 or it with 1111000 and write it to 0xDFF034.
Without it you can`t get the state of it.

Maybe this help to find out where is the problem located.

There are only two disk versions supported, this has very unlikely to do anything with this issue.
I know the difference between a cd32 joypad and a two button joystick. The tecnoplus is not a cd32 joypad. What are the three joypads you have tried?

note ~0000768

CHRKUM (reporter)

okay, was long long time ago don`t know why there is only disk one.
But there are no access fault while game and the game starts, not like
unsupported versions.

One Atari joypad, one of a Sega and a red Amiga Joystik - don`t know its name
its away already.
The connections are as i sayed and works from disk without any problems.

I close this. If anybody can reproduce it let me know or reopen it.

POKEB &hDFF034, (PEEKB(&hDFF016) OR &b11000000) REM Fire2+3 aktieren
delay 1 REM warten
c%=PEEKW(&hDFF016) REM auslesen

Das delay 1 sollte man im spiel natürlich nicht verwenden, da reicht ein kürzerer

Dann würde es ohne WHD nicht funktionieren, tut es jedoch.
Lässt man das aktivieren weg kommen keine werte mehr auf dem DFF016 register an(120R), bei 0 Ohm

Weiss nichtmehr welche es nun war aber hier ist z.b. was:

If you set the output enable for any pin to a 1, the Amiga disconnects the
potentiometer control circuitry from the port, and configures the pin for
output. The state of the data bit controls the logic level on the output
pin. This register must be written to at the POTGO address, and read
from the POTGOR address. There are large capacitors on these lines, and
it can take up to 300 microseconds for the line to change state.

To use the entire register as an input, sensing the current state of the
pot pins, write all 0s to POTGO. Thereafter you can read the current
state by using read-only address POTGOR. Note that bits set as inputs
will be connected to the proportional counters (See the description of the
START bit in POTGO).

I don't see anything about resistors on the button line here http://pinouts.ru/connector/9_pin_D-SUB_male_connector.shtml do you have any resource regarding this?

you write a byte to potgo which is word register! this will write a random (mirror) value to the low byte of potgo!

the correct basic example would be probably doing this at start of each vbi:
c%=PEEKW(&hDFF016) REM auslesen
POKEW &hDFF034, hc001 REM rücksetzen der werte

please test the attached updated slave.
I changed the game to write $c001 instead of $c000 to potgo after each read from potinp

note ~0001216

CHRKUM (reporter)

there is no resistor in the button line. the button is a resistor inself.
have you never opened a Remote control for a TV?
There are the Board with Zn contacts then there are such rubber keys, they
have about 200 Ohm. Its simply no Metal.

Word, i know but this should not touch the other byte part. i recheck that.
But why do you write direct values to DFF034, that activates for example
the Menu.

It takes still about 3 seconds of pressing, but there is a difference.
After the first wappon fire the others follow immediate while holding the
i think it should set in front of every read and a low delay between ;)

note ~0001222

Wepl (manager)

the custom chip bus is 16 bit wide and will always read/write words, it's impossible to write a byte...
why do you want read potgo before writing it? readable are only the dat bits anyway! for system conform coding you have to use potgo.ressource!
what Menu?

I have changed the routine to toggle between input and output mode, please test attached slave.

note ~0001225

CHRKUM (reporter)

okay thanks for the info.
I read the actual state OR it with the state i need, write it and then read it out.
this works since years, i use a amiga as an security system.

With your basic example the Workbench menu is activated because of
POKEW &hDFF034, hc001.

Thanks, it works now like original. can you do the same for Turrican 1?

I will remember it for Turrican 1, but I'm reworking this for some years now, a release date is not yet in sight...

the updated install has been released.

hi CHRKUM, can you please try if the modified slave attached to #2113 still works for you?
