ROMPAKS
From: BRICKCITY To: ALL

I am trying to find out if there is anyway to transfer programs fromompaks to
disk. I am trying to eliminate the need of unplugging the disk control so
often. Unfortunat, I can’t afford
n. Any assistance from anyon will be greatly appreciated. Thanks.

    Of the four CoCo 3 ROM paks that I know to be out, I know
    (and have posted here) how to transfer two of them
    (Shanghai and Thexder). Some of those coming out
    may well be UNTRANSFERRABLE.

    Each Coco 3 ROM pak as it comes out has to be evaluated
    by someone competent to disassemble them and figure
    out what is needed to be changed, then you must add
    the appropriate loader. It is a tedious business,
    and must be done individually for each one as it
    comes out.

    MOST CoCo 2 ROM paks can be transferred to disk using
    one or another commercial ROM-crack type program.
    I believe Microcom may sell one such, along with
    POKES to fix most of the Coco II type ROM paks.

    There are also instructions posted in the Games Library on how to
    put Springster on disk. They were done by Mike Ward and uploaded
    by me.

    A long while back I looked at Springster, and was able to get it to
    RUN off a disk file, BUT the version I had would boot up in
    an unplayably hard level. It SEEMED as if some sort of added
    “protection” was at work. Does your “crack” deal with this problem?

    As a matter of fact, this crack does give a version which has the
    potential of giving you a unwinnable board, either the first or
    the last (also the first level). I sent electronic mail to the author
    but got no real answer.

    I recall seeing Springster generate some unplayable boards
    but I can’t remember what I did to square it away.

    I plays at an extremely difficult level so I figured out
    a few pokes to slow down the bad guys and it plays fine here
    on my Coco.

    Is it possible not ALL of your rompak code made it to disk?

    Since Springster behaves differently when running in RAM as per your
    and Mike’s transfer arrangement, one can assume that Mike’s
    “crack” is not quite perfect, and that some beastliness
    in buried (probably, but not necessarily intentionally) in
    the code to specifically cause those headachs
    in versions that one trys to run off disk.
    A truly PROPER crack would NOT behave in the SLIGHTEST BIT
    differently on boot up from the ROM pak itself.

    Now, to be fair, Mike Ward is THE single most adept game
    modifier / cracker in the CoCo world. To my knowledge,
    not only does he rank #1, but there is no one really CLOSE.

    I did briefly chat with Mike about that oddity of his
    Springster to RAM instructions, so I am sure he is
    aware of it. I suppose he just had better things
    to do than spend HOURS painstakingly disassembling
    the thing to find whatever it was caused that weirdness.

    From: MIKEWARD To: MARTYGOODMAN

    Marty, and Zack,

    I know exactly what the difference is between running Springster
    in RAM as opposed to ROM is.

    The game moves itself to RAM and fires up after modifying itself.
    At one point during initialization it switches in the ROMs
    to read a few bytes (hopefully from the game pak.)

    Depending on what your disk ROM looks like when it reads these
    “few bytes” is dependant on what disk ROM you’re using since you’re
    running it from disk.

    The “impossible game” scenario, like walls you can’t get around
    or climb, is symptomatic of possibly not getting the game on
    disk properly or a defective bootstrap to set the game up
    to execute when loaded from disk.

    Hope some of this helps.

    Mike

    Er, well… then…

    Is it possible alter that attempt to “read a few bytes from
    the ROM pak” and, instead, sorta FEED the program the data it
    WOULD have seen had the pak been there?

    Or is that “take a peek at the ROM” code itself booby traped
    so that, when altered, it messes something else up?

    I considered tinkering with it to see if that could be done.
    I seem to recall I had trouble finding where the routine
    was called.

    I’ll try to remember to look at it again this weekend.
    I’ll supply some details as I stumble across them.

    Thanks much. Ill be interested to hear
    the results.
