    Hello.

     

    I stated to dig a bit into how C64 graphics works. As I understand there are 8 sprites. And they are 24x21 pixels. Right ?

     

    I have programmed on the TMS99X8 VDP (Memotech, ColecoVision, MSX) and a bit on Intellivision. I think its a bit confusing why its 24x21 pixels ?

     

    So I can display 8 sprites at the time each is 24x21 pixels ? - I wonder why its not 24x24 pixels. By anyway, look forword to learn more about the C64 and its graphics :)

    Haha! I just saw a video of the original, and the car explosion is there as well. :)

     

    Great job, it does look like the original version.  Now you need to simulate the old PC DOS fonts. ;)

    PC fonts might not be so easy :) - I the original game in archive.org browser, but the pc version didn have a "explosion", but i think some random sounds when the Donkey is hit. But the Donkey and the Car fall apart. I took and modified it a bit, so basicly I took the explosion sound from SuperMinefield, and changed it a bit :)

    Hi there.

    I spend a day or so to code this game. The Donkey is almost pixel-perfect to the original dos game. I found the source and used mspaint to zoom in the pixels so I could draw the sprites in a Sprite Editor. The Donkey Is made up of 3 sprites (8x16 sprites). The Car is made of 2 sprites, x-fliped.

     

    Donkey.Bas - an Intellivsion version of the old DOS basic game made by Bill Gates & Neil Konzen.

    The Intellivision version is coded in IntyBasic, and was programmed by CrazyBoss 7th-8th feb. 2021 almost 40 years after Bill & Neils DOS Basic version. The goal of the game is to avoid the Donkey, by pressing any key or disc position at the controller. You can press CLEAR at the controller to reset the game - When you pass a DONKEY, your car moves closer to the top, when you past 10 Donkeys, you will earn a point and the game starts over again. If you crash into a Donkey the Donkey (or maybe another Donkey) will earn a point. The Intellivision rom file is around 7kb - I dont think you will ever see a cartrigde release of this version.

    Hi.

     

    Any point function in intybasic. I read in the manual for intybasic:

     

    COL7
        Returns the collision status between sprites for the current frame. It is
        best to use these after WAIT.
        Don't forget to set the interaction bit in sprites (bit 8 of X-coordinate)
        bit 0-7 means collision against sprite number.
        bit 8 means collision against background pixel (pixel set)
        bit 9 means collision against borders

     

    If the sprite touch a background pixel ?

    Solved after download the right package:

    "The Microsoft Visual C++ 2008 Redistributable Package (x86) installs runtime components of Visual C++ Libraries required to run applications developed with Visual C++ on a computer that does not have Visual C++ 2008 installed."

    I tried to install Coolcv at an older laptop, running windows xp sp3. But it failed to run. Together with help from Oscar I tried to get it work but until now no luck.

     

    Also tried to install C++ distributables.

     

    I need to use windows xp, cause my eprom programmer run on windows xp only.

    I don't know how many emulators there are, but I just tested with WinVICE 3.4. Apart from the fact that my mouse pointer disappears, it runs Sargon II and other games fine.

     

    Download the PRG file (8194 bytes) and attach it as a cartridge. The emulator will automatically reset and start the game. Adjust screen position with cursor keys. The game doesn't seem to work with symbolic keyboard mapping, you have to change it in the settings to positional keyboard mapping.

    Hmmm.. I recall it crashed on earlier versions of WinVICE. Anyway I downloaded the GTK3VICE-3.4-win64-r37296

     

    But it dont run on my windows 10. When I click at the emulator file, it shows a commodore icon at the taskbar for some seconds and then its gone again. I dont see any setup files, I assume i just extract the folder to my computer and run the emulator exe files inside that folder, tried to run as administator too. Same problem.
