American Truck behaves in a really strange ways... I've tested the joustick with many games, even disabling keyboard and they are fine, but this game no way!
Is there something I don't know about it ?? Does it uses joysticks or paddles ?
Actually joystick is emulated reading port a2, and it should be right since it works with many titles... Sad

Concerning the 5th sprite can you make me an example of a game you saw showing the problem ? So I can analyze better the problem...
Thank you for help and support.

Found also that if I disable joystick reading it works with normal keyboard... So the problem is not the keys reading routine, but the way of reading data from port a2 and registers 14 / 15 of PSG Sad

I points you three games that shows the problem.

maybe you don't know how originaly it must be.

somebody can upload screens of athletic land / artantic adventure / Artantic adventure II / etc etc. how looks originaly. I have no real msx here.

In athletic land, in the stage of little "wather-holes" where ducks or fishes jumps up/ and back down. When a duck o fish just appear, it only must show the HEAD (like 2 or 3 pixels), NOT THE COMPLETE BODY. That trick is done using several sprites (with higher privilege) in underwather scan-lines so, ducks sprites are not rendered by vdp completely, just the 2 or 3 scanlines of the duck sprites.

do you understand?

In artantic adventure, when the pinguin just fall in a hole, the body is hidden with the same trick.

and so on... in many games.

If you enter a shrine in The Maze of Galious, the 5th sprite is also used to hide the lower part of the main character sprite.

Oh yes you are right! What an idiot mistake!!!! I counted the 5th sprite starting from 1 and not from 0!!! Working in the night is not a good thing for emulators!!! Big smile
Now it should work... the penguin fall in the hole correctly Wink

Actually I'm still working on the American truck joystick problem...

Thank you very much for your help! Really!

for joystick problem, don't overlap everything to the arrow keys.

in several games, if you touch one command it will disable the rest, and that can be happen in american truck

just redirect the joystick port to the numpad, and arrows is just for allow keys.

WEIRD!
in your opinion, why the "alternate" version of the American Truck works perfectly and the normal one not ???? I've just tryied the [a1] version and there are no problems with joystick!!! I'm confused Sad

Hi guys, It's a lot of time since my last post... And my little Actionscript MSX emulator has grown up Smile

I've implemented the subslots and the Arabic MSX computer al Alamiah AX170 .
A very interesting MSX computer dedicated to the Arabian market.

I was asked to build up a special version of my emulator to work online on www.gametako.com :D

More games will come :)

Hope you will like it!!!
