    Always wondered it the Atari 5200 could render an acceptable version of 1942

     

    even the "similar" game Screaming Wings on the XE is Awful,

    can a better version even be done?

    no it cant without the xm. no wonder the coleco kicked its ass!!

     

    5200 XM? Where?

     

     

    There's no 5200 XM

     

    Jinks was just trying his best to be funny,

    of course all he did was confuse people,

     

    sorry

    Indeed it did back in the day!

     

    Love the colecovision too though,

    though the 5200/A8 is my fav console ever

    agree, but that was not the case with adventure island 1 to 4,

    just bankswitching and stock chips

     

    Actually, according to this document, Adventure Island parts II and III use the MMC3 mapper (just from having thoroughly played those games myself, I had a feeling that was the case). The original Adventure Island also uses the CNROM mapper. I'm not sure how big of a difference the CNROM makes though.

     

    CNROM usues discrete logic to provide up to four 8 KB banks of CHR ROM which would not otherwise be present in a "stock" NES.

     

    So, it evidently appears a "stock" NES could not handle an "Adventure Island" type-game. It needed an NES XM...er...sorry, extra memory and logic banks not present on the system itself.

     

    In fact, per that document only the games - and very few indeed - that ran on just a "stock" NES are the ones that show "(0) ----" as the mapper. Everything else required an XM...er, extra hardware.

     

    For the record, I love the NES...second classic system I started rebuild collecting again, after the 7800. Prior to my losing my entire classic collection I had over 200 NES carts. I'm a little shy of a 100 now, and have a Power Pak. Much love for the NES here, just like to have facts straight, especially with an underrated and mishandled system as the 7800. ;)

     

     

    Good to know!, thanks

     

    Always thought basic mappers allowed bankswitching

    Castlevania 3 being an entirely different story

     

    Wondered if stock 7800 could handle a platformer

    And now i discover even stock nes can't do it -if you 're right-

     

    what about master system and c64?

    so in essence for the 7800 to do a Wonderboy-Like Platformer,

    it needs an expansion

     

    no wonder the Nes kicked its ass...

     

    Right...Becuase "stock" NES hardware accomplished it all: http://en.wikipedia....ment_Controller

     

    "These chips extended the capabilities of the original console and made it possible to create NES games with features the original console could not offer."

    i will always prefer anything Atari related

    , but let's be just a bit impartial please

    Hey Shawn, not a bad idea - I'll do the game first, and if I can fit it, I'll make it autodetect if the XM is present (like the Pac-Man 320 / Ms. Pac-Man 320 games). Only if I can fit it, though.

    Your "Wonderboy question" was answered twice.

     

    not at all

     

    here we go

    again:

     

    adventure island nes has pokey like sound

    as well as wonderboy master system

    so can a "Wonderboy like" game ,

     

    and by that i mean similar multichannel music quality,

    similar effects, sprites , scrolling,etc

     

    be made on stock hardware? bankswitching and pokey allowed?

     

    just theorizing here...

     

     

    don't care if this particular game ends up being for PS4

    Why all this hate for the XM. Its there to help homebrewers to make cheaper games. With it you don't need to add pokey or ram to each cart. It provides the use of components that were already design to be used with the 7800 back in the 80's.

     

    i don't hate the XM, just don't care for it...

     

    the stock 7800 witch CC2 and pokey is the most i would upgrade the system

     

    i would very much like to see what is posible and what's not on it

    hence

    my wonderboy question...

  10. Posted

    adventure island nes has pokey like sound as well as wonderboy master system

     

    so here we go again:

     

    Is the 7800 capable of a wonderboy/adenture island quality game?

     

    -adding pokey sound chip ,

    bankswitching, all thay you want-

    but on stock hardware?

  11. Posted · Edited by fernando marrin

    just wondered if a Wonderboy-Type game

    is too much for the 7800

    so that it requires an expansion

    At the moment, if I were using TIA sounds, no - it would not. I chose to use better Pokey sound, and because I am using the address area where the Cartridge Pokey usually sits ($4000-$7FFF), I need the XM for the non-standard Pokey location.

    So, being that I am already using the XM, If I can make the game better by now using the XM RAM available to me I will. :)

     

     

     

    Thanks, guys (again) :)

    Bob

    checked Screaming Wings Amiga version

    on the real thing

     

    nothing to do with 1942

    uses modern planes,

     

    looks more like raiden

    so i guess we'll never know...

    Dreadnaught Factor runs very smoothly, although it scrolls vertically very slowly.

    \

     

    but Dreadnaught Factor does not have lots of sprites moving,

    nor big airplanes rotating

     

    will check screaming wings

    on the amiga to see if the guys that made it were just lazy or limited by hardware...

    Not sure why one would homebrew a game for an expansion that no one had and very few will have. How is that 7800? Maybe adding additional features like an enhanced soundtrack for the XM, would be cool, but the game should still have a native 7800 soundtrack, as awful as that might be.

    i actually like the c64 version

     

    though i'm not sure if the A8 is as capable moving that many sprites

     

    at least by looking at screaming wings and its fake looking big sprite planes

    I now own a 2600 Jr and am still at bit in awe as to how compact it is. As a kid we had a 6 switch Sears Video Arcade and I remember that thing being both large and a bit on the heavy side (no doubt exaggerated by my memory as a little kid when everything seemed big and heavy). But side-by-side there is no doubt that the Jr is noticeably smaller.

     

    What did Atari do when they redesigned the 2600 for the more compact/lighter base?

     

    they just removed plastic...

    i've a Sandisk 1 GB compact flash with adapter ,

    and ide images + SIDE fat 32 games,

    works like a charm on my firmware 4.7.04

     

    but makes my cart too big

     

    would love to make the 512 MB trascend Work, At least full of images

  22. Posted

    hi everyone !

     

     

    have a 512 trascend card and atarimax divide+flash cart

    can't use side because my computers don't have ide anymore

    to format the card

     

    even try in my friend's house and the card was not recognized by his bios

     

    so all i have left is image mode

     

     

    trying to copy 320+ 2D images with multiple games

    -the ones that are online and come with lotharek's sio2sd-

    i find myself out of "pages" around 200+ images

     

    how big is image mode in my card?

    how can i make even this collection fit?

     

    the complete files collection on the sd is only 60+ mb

    I used to have a Telegames Personal Arcade-now it's junk. At times the screen would turn black and white with static noise. I bought the game Alacazar and had to return it due to glitches-now I believe it the machine's fault- not the cartridge. The pause button was probably made for the SG games but cannot test- I fried the thing after trying to replace a cap and gluing a heat sink on one of the chips. I even broke the power connection and thing just went south.

     

    replacing the video chip and a good heatsink fixes this

    Perhaps the biggest flaw with the DINA is that there's no heat sink at all on the TMS9918, even though it's a required component.

     

    there were heatsinks on both my Dina and Telegames personal arcade

    Thinking about it some... a Ram-based cart (which can be write-protected) with some Rom (for bootstrapper), a latch (for /Command line) and companion plug for the expansion port - a system could be devised to load software over SIO2xx devices (or real 1050).

     

    I've thought about it some too. The 800 uses PIA signal CB2 to generate -COMMAND and it uses SKCTL mode 2 to transmit data and 1 to receive. The 5200 has no PIA, of course, but if we use SKCTL mode 6 to transmit, then data gets clocked out at one rate and we can output a signal at a different rate on CLOCKIN. If we wire CLOCKIN to the drive's -COMMAND and program it to generate the one long pulse, then we get all we need without adding a latch nor any active circuitry. Haven't tried it but I think it should work.

     

    As you said we need a ROM cart for the SIO program and a mini-DOS. It could be a read-only DOS just for loading 16K games into RAM, or it could have some write capability for saving game states or scores.

     

    And like you said the cart could also contain RAM. We would have to wire two signals (R/W and Ph1) from the expansion port to the cart to support the RAM. 16K or 24K of SRAM would give lots of room for bigger games.

     

    Maybe we don't need it today, but it could have been something back then.

     

    i love the 5200 because it's really a console,

    with all the letters,

     

    adding Dos could turn it into an Hybrid,

    much something like the xegs

     

    which may loose some of its appeal,

     

    at least imho

    will it have the awesome soundtrack of Tempest Xtreme?

     

    I'm not 100% sure, but from what I've heard & seen, Tempest Xtreme is a port of Tempest 2000 - a different game with far more memory available for it. (1Mbit?) 5200 Tempest will be the coin-op port we wanted back in the day, with GAME SOUNDS as our accompaniment. :D

     

    tempest xtreme is based on the unfinished 5200 game

     

     

    Tempest Xtreem is a mixture of the original Tempest with elements of Tempest 2000, including music, speech and some game play elements.

     

    ok

     

    but was it based on the 5200s Tempest code or not ?
