    UK PAL 7800 - composite video output modifications?

    in Atari 7800

    Posted · Edited by Schmutzpuppe

    I made a new S-Video circuit for my NTSC device and I also tested it with the PAL one.

    All I had to do was to add a resistor and a diode (else the TIA produces too much distortion which didn't happen on NTSC).

    The circuit doesn't use irritating potentiometers and had a slightly better picture than the one I did before.

    I'll try to write down the circuit maybe it helps you to build your own one.

    That’s for the input guys.

    I tried to remove the flicker issue shadow460 mentioned.

    With my NTSC device I don’t have a flicker problem but it has a very bad video out so maybe it’s just not visible for me.

    I made some additional changes:

    Trigger works now with Proline and standard joystick.

    Now you can pause the game.

    PAL crocodile graphics bug removed.

    Cartridge Pokey/XBoard Pokey detection (doesn’t work on Prosystem Emu because SKREST/RANDOM is not supported)

    When pressing “Pause” during the title screen you enter the option menu.

    First you get a screen where you can adjust the Y-Position of the playfield with stick up/down.

    That could be interesting for NTSC users because the game uses the whole vertical screen and maybe it helps if your TV isn’t able to show the complete screen with default setting.

    If you press “Pause” again you enter the sound menu where you can toggle between TIA, (Cartridge) Pokey and XBoard sound.

    It would be great if any XBoard user could tell me if it works for him.

    Shadow460 mentioned that there is no color change if you pick up the lady frog like in the Arcade.

    That’s true but I can not change it because the frog and the snake share the same color and that would mean that snake would also change the color :(

     

    OK, I tried it in the CC2 with the Pokey removed. It's playing music but no other sound effects when it's playing the tune. Also the song's notes are not playing with the right tempo. It will go fast then slow than fast again as if it's getting slowed down at times by the program.

     

    With this version would it be playing the music if it can't access the Xboard. Another words, does it default to the TIA if it can't access a pokey anywhere?

     

    With the Pokey in the CC2 the music and sound is fine.

    If you hear no sfx than it's TIA.

    Do you entered the option menu for sound?

    In the menu you can see the current setting and also select XBoard sound if it wasn't detected.

    Hallo Matthias :)

    eine wirklich gute Version.Allerdings ist beim grossen Krokodil noch ein kleiner Grafikfehler.

    Auch die TIA Version ist ganz ordentlich.Habe aber folgendes festgestellt.Wenn ich während des Spielens "Select"drücke,dann wechselt der Schwierigkeitsgrad(????).

    Gruss Walter

    Ich hatte keinen Fehler bei Krokodil mehr!? Wie äussert sich der Fehler bei dir?

    Das mit Select stimmt, ist noch zum debuggen, damit springt man in das nächste Level und bekommt wieder drei Leben ;)

    Thanks for posting. Great digitized sound and cool AtariAge intro! Any instructions anywhere?

    Unfortunately there isn’t but thankfully godzillajoe made a good summary of what it is about :)

    Here is the binary for you.

    Merry Christmas everyone.

     

    Nice game. Thanks for posting it. So what's the story about this game? Was this your idea?

     

    Allan

    Simon type games are well known but the inspiration to make a xmas style game of it came from a little flash game called Xmas Simon (http://www.flashangel.de/xmassimon/)

    I found it mid-November and because I thought it is a nice (and simple) idea I stared coding Santa Simon the same evening I found Xmas Simon.

    Most of the code was done within two days and since I am not a great artist I looked around the Internet for some graphics I can use.

    The graphics you can see in the game are based on free gif's I found while looking for some xmas gfx.

    A big thanks to the unknown authors!

    When I was sure that I could finish the game before Chrismas I asked Albert if he likes the idea to release a xmas type game for the 7800.

    He agreed and gave me very helpful feedback about the work in progress.

    I am very glad that he wanna make a cartridge out of it even if the timeline was very short and when I saw the bunch of stuff in the store for chrismas sale I thought he definitely have enough work with it even without Santa Simon.

    Albert was also the one who managed that Atariboy made a great label for the game (I really love it).

    In other words the Santa Simon Cart wouldn't be without him, thanks man.

    Games done better on the Atari 8-bit than Apple ][, C64?

    To make it short (nearly) all early released titles are better on the a8

    Later there are a lot of C64 which are better or never released on the a8 like Impossible Missions or Winter Games.

    It’s always the same if a Game is programmed for a particular platform the conversion is weaker.

    Anyhow overall I like to play the a8 versions more it feels like… like more fun?

    I can’t say what it is but surly there are also some great titles on c64 (no opinion about Apple here)
