  1. as far as I can tell, it should use a 16 bit mask to select the pixels from the sprite.

     

    in Y it somehow seem to do something (but somehow only every second line), but it wont work for X, will stop after few columns.


  2.  

    You mean two Lynx'es w/o ComLynx-ing? While developing T-Tris, I did download the game to up to 4 Lynx in paralell w/o problem.

     

    Regarding the diode: I found the hint in another forum. I tried an resistor but it did not work. Too bad, I cannot remenber the explaination ...

    Not so much for the uploading.

     

    PS: parallel upload to several lynxes never worked reliable for me.


  3. I found a already equipped board with a dual interface using this chip:

    Nice thing, you can connect two lynx at one USB cable. but only one of the connections features "unusual" speeds like 31250 and 62500.

     

    Annoying thing, shipping is more expensive that the boards :-(

     

    42bs: I was wondering about the diode. its clear that it prevents the TX from pulling the line while the lynx is sending. but wouldnt a resitor do a better job?


  4. PS. I was wondering if it would be ok to output the code as cc65 assembly source with some switch. This would be quite useful when making compilation carts. You could then build BLL games into separate segments and use cc65 linker to create the cart.

     

    I am not sure if this is so easy. Because you would have to handle only some of the macros, but keep the labels.

    Will do as soon as I get to my own computer! I'm surreptitiously misusing workplace resources to post this message. That said, I don't actually have anything immediately to assemble, so appropriate feedback may be delayed. I was a heavy Lyxass user a decade or more ago but all my work is lost to time, at least in its original form.

     

    Thanks again! But does this mean we're the last people left alive using this assembler?

     

    No. But most people use some already compiled binary.

     

    Meanwhile Bastian completely rewriting his assmbler from scratch.
