Tank Wars (1983)(OEM) :
It's a 2 Player game.
Does anyone know how to control/steer the second Tank using VICE ?

I want to say you need the OEM 2 player adapter for this, but I'd have to consult my original box to check.

According to MegaCart:

"Joy II Required"

so, no chance to play it in VICE ?

In userport joystick settings select PET userport and set port#1 to none and port#2 to Keyset a or b. Then to configure that keyset,

North is actually East so if your were going to use W for north, S for south, A for west and D for east then set:

North = D
South = A
East = W
West = S

I haven't figured out the fire button yet.

And don't forget to enable joy keys.

Great it works

....if figuring out the fire button key, please post it

Ok, set Port#1 to the keyset that wasn't used in Port#2.

Then for port#1 keyset change EAST to the fire button that you want.

Hope that makes sense.

I think Mayhem is correct above in stating that Tank Wars uses the OEM adaptor. But it seems that OEM emulation is currently broken in VICE.

I've added a report to Bug Tracker, maybe someone will fix it soon.

I'm not sure if it's emulation or the cart dumps, but yes, a few of them need a soft reset to work after you've attached them in Vice.

I meant that the OEM userport joystick emulation is broken.

Here's a test program that I wrote to test userport joysticks. userjoy.prg

It's for the unexpanded VIC. It just mirrors the bits from the PortB I/O register ($9110) to the first 8 bytes of screen ram.

You'll see that for the OEM userport joystick in WinVICE 2.4.x only bit 0 changes, when bits 3-7 should change. It works fine in WinVICE 2.3 and earlier.

Ah, gotcha! Either way, I'm not sure I'd be able to edit the GEMUS script to configure this to allow two players in Gamebase. Unless someone can figure it out...

The OEM userport joystick has been fixed in the latest build of WinVICE.
