  1. Altirra does support two paddles, but you need to edit the input mappings for it. You can either clone the existing paddle input map and change its controller from Paddle A to Paddle B, or set up the X/Y mouse axes to drive both paddles simultaneously as in Atari800WinPLus.

     

    Paddle jitter is one of those annoying hardware aspects that you have to experience on real hardware... although, believe it or not, there are 5200 games that break if it isn't implemented.

    Thanks - I will try this when I get home.

  2. You like rainbows then...nice looking DLI

     

    Is that standard or VBXE-ified

    Standard. I am using a custom display list. GTIA mode 9 in narrow mode. This gives me 64 pixels per row. I am repeating each scanline 3 times (via LMS commands) and also triggering a Display List Interrupt every 3rd line. This gives me a 64*64 pixel screen which puts all 256 colors on the screen (4 times). To save memory and processing time, I am mirroring the top half of the screen like 1 2 3 4 5 ... 32 32 31 30 ... 1.

     

    The colors will not be static, but for now I am just getting my screen and controllers up and running. Animation and sound will come later.

  3. Candle also told me the AOSD project was more or less put on hold indefinitely. A shame. No reason at all why you couldn't have four of your favourite OS's on a custom EPROM which would sit in an INTSDX adapter. Anyway, I'll say again: excellent work. I'm looking forward to the next batch of photos.

    Thanks for the kind words - it's taking some crazy time. I spent a few hours this evening, got all of 9 wires put in harness and routed. I'm taking my time with the harnesses though and not trying to set any speed records.

     

    Bummer about the AOSD I had planned on getting one. Oh well - hopefully the Speed Drive will be my next bug purchase.
