    yes, I was looking two days ago also at the graphics of Gauntlet, and thought they were using mode 4, because it the ghost etc are moving like characters, but when I saw the display list i thought too : why ??

    on the 8 bit you can change the player's color on every scanline, you'll have to make a sort of kernel like this :

     

     

    LDA PLAYERY ; Y POSITION PLAYER

    STA VC ;STORE IT IN VARIABELE VC

    LSR VC

    LDA VC

    TAY

    INY

     

     

    UNTIL

    STA WSYNC ;WAIT TILL OFF SCREEN

    CPY VCOUNT ;ARE WE AT LINE TO BEGIN CHANGING

    BNE UNTIL

     

     

     

    LDX #0

    LOOP LDA COLTABP0,X

    STA COLOPM0 INX

    CPX #27

    STA WSYNC

    BNE LOOP

     

    there is a register, vcount where a value is stored on what line the atari is drawing, if it's the line where the player is you can change color

     

    the example above can give a player 27 different colors, and the colors are stored at coltabp0

    I think you have to run Fdisk first, and try to make a partition. If the program doesn't recognise a HD there, then there is something wrong. Have you made the cart by yourself ? I did make the internal version some time ago, and not all harddrives worked with it. Most Quantums did work.

     

    Make sure you run the program from MyDos ( I assume you did)

    I have made some sort of cartridge reader/writer, and i have read out some of my cartridges. but now i wanted to read out 32KB/64KB/128KB carts....so i read about it at the atari cartridge dumping project. Now, I have read out my starraiders 32KB cartridge, and tried it with atari800win...and it works ! . Then I tried food fight and crystal castles, which should be 32KB and works with the same principe ? am i right ?...But they don't work...I really don't understand why starraiders works, but why food fight and crystal castles not..?

     

    and works Ballblazer and other 64KB XE cart like this ? 7 banks at 8000-9fff and the last bank at a000-bfff ?

     

    Thanks,

    I have a 21 inch monitor, with RGB in only (and vsync and hsync). Right now i have connected it with my pc, and it works good. Now i was thinking can i connect it to a XE/XL ? can i get rgb out of it, do i need vsync/hsync signals ? The monitor belonged to a apple macintosh, which only had RGB connected with it.
