    best graphics on the lynx

    in Atari Lynx

    Posted

    Alpine Games because it is one (if not the only game) to use high color which is incredible stuff.

    You forgot the fact that "Lynx Reloaded" is the only other Lynx game to have and use Bjorn Spruck's "high color mode" graphics,not just Alpine Games.

     

    Thanks ;-)

    But no surprise, its the same code.

    In fact the CGE slideshow cartridge is using high color code, too. And here it is really "high" color. In alpine games for space reasons the picture are only up to 256 colors.

    I had some other stuff in the pipeline, but no time to finish it... see examples on my webpage.

     

    (only if your a BLL cable, a flash card or an eprom burner:)

    MOD music on LYNX?

    there is also a PC version available from Sage

     

    ... which I can put for public if you agree. This converted also includes the player for quick testing on the lynx. Loader Cart and serial converter cable requiered.

    MOD music on LYNX?

    in Atari Lynx

    Here are some more facts about LynxMod, the MOD-Player

    has a replay frequency of 6khz, during development we experimented

    also with 8khz which sounds of course better but needs more memory and

    cpu time. Biggest Problem on the lynx is the small main memory.

     

    You are right sorry, 6.2kHz not 2kHz, my mistake.

     

    But this depends on the timer you use for replay. If you want to save cpu and can live with less kHz, you are free to do so.

    Your code is using HBL as timer, but in principle this is up to the coder, the lynx have enough timers ;-)

    Btw - there are many PC-editors for ROM/DISK images (for Spectrum it's Spectrtum Navigator, there are similar for C64, for Atari etc); my question is - are there any such editors for Lynx?

     

    Hm yes, but its unofficial.

    Anyway its hard to change things in an existing ROM.

     

    Oh, I see. It's very interesting.

    Is any possibility to get the player somehow? (If it has any 'user-interface' as maybe it's only an engine for other programs).

     

    I mean - if there is some MOD-player with user-interface, and I would like to add to the LNX ROM some new MOD, could I do it on PC via some ROM's editor?

     

    well i have a piece of code which is doing nothing else that playing all mod files in the rom.

     

    But now comes tha bad part:

    the mods have to be in a special format, thus you have to convert them. The replay frequency is only 2.xkhz and the memory you are allowed to use is roughly 40kb. but for a game with double buffered screen and some gfx and code it would be more like 20kb. And mostly no effects are supported.

    The MOD player eats up to 30%-40% cpu depending on the replay freq.

     

    Using in games and demos: Lynx Reloaded, Alpine Games, Sokomania, ...

    The T-Tris in SIMIS

    in Atari Lynx

    Posted

    I've been playing the SIMIS version of T-Tris and even though it's referred to as a reduced version, it seems complete enough to me.

     

    What I'm wondering is, how many of you own both T-Tris and SIMIS? Can you compare the two?

     

    Would it be worth my while to own T-Tris? What more is in the real release?

     

     

    If I remeber correctly the SIMIS version is with less/without(?) samples, but i might be wrong here.

    Sound, Blank Screens and ASM

    in Atari Lynx

    Posted · Edited by sage

     

    I have, I couldn't get obj files created by Sprpck to convert to olb files. I'm not too keen on how to use cross langauge sources (especially how to compile a C and ASM combination source) so I'm trying to stick with one programming language until I get a better grip on it.

     

    This is easy:

    
char variable;

functionname()
{
#asm
 xref _variable

lda _some_variable
sta #$FDB0
#endasm
}

    Sound, Blank Screens and ASM

    Ok, first off, I know I should have posted this under programming but my other attempts to get help in the subject of programming for the lynx have gone unanswered.

     

    Everything I see for programming sound is all written in C, all my tutorials are in ASM so it makes learning how to write programs for the Lynx difficult... Secondly I've written a little demo based on the ASM from the Tutorial I've been following yet I get the text but the screen is always blank, I've gone over all the display definitions AND the sprite defs and can't find anything wrong.

     

    Anybody who is developing for the Lynx writing in ASM? If so, a little help please.

     

    Source

     

    You might have seen this:

     

    LynxDev

     

    Sound:

     

    look into sound.asm / .def / .mac in the BLL package.

    This might give you an idea how to use the sound. This engine is quite powerful but very hard to compose sound for it.

    Well, you are finnish. A sauna is basically a really big oven. Turn it up to the max, get some cold beer and go sit next to your PCBs and watch the paste melt :D

    The beer won't stay cold in these temperatures anymore.

     

     

    The problem is not so much the beer, but the glass bottle gets hot in the sauna. This might burn your lips. Tested that on my last trip to finnland.

    What carts are these?

    in Atari Lynx

    Posted

    I got them for right at $20 each... but can't figure out who made them... or what exactly they are. Are they some knockoffs or something? Perhaps something from Best Electronics in the early 90s? I though it was B&C... but I think their stuff actually states B&C.

     

    If anyone know... please let me know! Thanks

     

     

    T-Tris is a homwbrew (well... the very FIRST one)

    It is a BLL style Cartridge developed by BSchick/LBaumstark.

    How about some stuff from the Lynx programming contest 2004:

     

    Push around the world

    Space Battle

    Stardreamer

     

    How many titles would fit onto a Lynx cart anyway?

     

    Push around the world is nearly 256kb size, already packed(!).

    But there would be anough space to fit a small "hidden" game if some gfx/msx is left out.

     

    Even if the multicard would be a 512kb cartridge, it would nearly impossible to include because it collides with the cartridge structure which was choosen.

     

    Anyway, I do not have the time atm to but enought work into it to finish the missing half of a percent..

    Different 'Batman Returns' Version?

    in Atari Lynx

    Posted

    Can anyone confirm this? I've tried all three of my cartridges, and in all

    of them Catwoman has red hair. I have even downloaded a ROM and

    tried it on the Handy Emulator. She had red hair in the ROM as well. So

    does anyone have a copy where her hair isn't showing? Let me know!

     

    Would be interessting to find a ROM with differences... could not be more than one byte

    Lynx Flash cart?

    in Atari Lynx

    Posted

    By the way... Cooper got one of these new laptops that lack COM-ports entirely. So I wrote an updated version of the Mttty.exe downloader that works with USB interfaces. If any of you who already have the devflash needs an updated version, drop me a line.

     

    I am also working on an enhanced version that allows communication over USB at 62500 bauds. The sending part is already there but I still need to flip a bit in the Lynx programmers binary to make this work.
