  1. That's what I get with my TV, on this and most (all?) other jaguar games. That's really why I asked people to test this for me, because I don't trust my TV.

     

    If I can ask one more thing, could you see the whole image (apart from a bit off the left), The white diagonal lines go to the edge of the image, could you see all of them on all sides? Also was the TV PAL or NTSC natively?

     

    You are right to not trust your TV, mine has the same "trouble" ... I must find an Atari SC1435 :)

     

    I don't see the left part of the picture (All the part with vertical and diagonal lines) and my TV is a very old one so it's a PAL version (but it accept PAL50 and PAL60 mode).


  2. Thanks for all the help, everything seems to be working just fine. However, my TV being a bit funny about aligning pictures sometimes (things tend to fall off the left hand edge a bit), I'm wondering if I can get some help testing this on various different systems.

     

    It doesn't really do anything much yet, just sets up 640x480 interlaced video.

    I'd like to check that it works on:

    • PAL and NTSC Jaguars
    • PAL and NTSC TV's
    • modern and old TV's
    • and how well aligned the image is on all of the above.

    Anyone who feels like testing this, your help would be very much appreciated.

     

    Source is included, feel free to do what you like with it (it's 95% code by Atari and Zerosquare anyway, my changes are minor).

     

    Thanks.

     

    Yop !!

     

    Tested with a PAL JAG with 50 and 60Hz on a old TV !

    Picture seems good. I just don't see the left part of the picture (but it's the same wit all my jaguar games so ... and this TV doesn't allow horizontal tuning ...).


  3. Transparence uniforme, tu veux dire soit 0%, soit 100%, comme les fichiers GIF ?

    Si oui, pas besoin de bricoler pour ça : c'est supporté en hardware, il y a un bit à activer dans la description du sprite pour rendre la couleur n°0 transparente.

     

    Il y a bien moyen de faire de la "semi-transparence" avec le mode vidéo CRY et le bit RMW mais ça oblige à utiliser un sprite en plus pour faire le calque et ce n'est pas super facile à réaliser (faut faire une tartine de tests avant d'obtenir un résultat intéressant) et de plus, ça dépend énormément du sprite de fond d'écran (il y a a risque de saturation des couleurs ...).

     

    Exemple :

  4. Starcat : yes, the EEPROM chip is the standard 128-byte one. But compatible chips with the same pinout and sizes up to 2 kilobytes exist, and they're not very expensive. That means we could offer a version with more memory, if there is enough interest ; or maybe we could only manufacture this version, if the standard Atari EEPROM code is compatible with larger devices (I don't know what happens in this case, we'll have to test it).

    Atari's EEPROM code is done for using only 64 word (63 Data + 1 CRC) !

    So It should not be very hard to modify the code if the read/write method for both EEPROM type is the same ... I think and I hope so old games could be flashed on the cart with a functionnal save... :unsure:


  5. Hello hello :)

     

    Can people with BJL Jags please try the BJL version of the game on their machines? Someone reported the game was failing on the menu screen, although zerosquare got it to work OK. If there are different versions of BJL around it'd be good to know that it works on all, to make sure we don't have some weird bug. Thanks!

     

    No problem for me with BJL ;)
