    Doncaster F18 EA5.zip

     

    Latest and probably last & final revision of Doncaster Racecourse.

     

    * Comes on 3 EA5 files for people to convert to cartridge if they want to

    * Fastest parallax scrolling I have ever programmed

    * Funky new tune

    * Horse names altered so kids can play it without asking "what is two in the pink"

    * Random 'sponsorship' banners (TI99IUC, SHIFT 838, CodeHackCreate are just a few of them!)

    * Exploits the F18A's ability to show more than 4-sprites-in-a-line. Real iron users need to have it switched the right way. Emulation users just turn off the Flicker in Classic or select F18A in JS99er.

     

    Loading ......

     

    Anyone who isn't sure how to use a EA5 ... select editor assembler cartridge and use option 5

    Type DSK1.DONNYA ... ensure the other files are present too. :)

    Hi everyone. I hope we are all well.

     

    Just a quick question.

     

    Is there any chance of a really clever TI guru making a version of Extended Basic that has CALL commands to support the F-18A?

    For instance, we could have a special CALL COLOR command that can have extra parenthesis to support more colours in the 8x8 character block?

    Probably not what anyone was expecting or thinking, but it would be really good. Either that, or I could bugger off and learn Assembly. :)

    There's an F18-A version of Doncaster Racecourse on it's way.

     

    Updates:

     

    * more clouds in the sky, not just 2 (each is two sprites)

    * each horse has a shadow on the ground (look at the Mame Rom 'Arlington Horseracing' you'll see where i got that from)

    * the horse you betted on has an arrow following it through the race

    * title screen has an attract mode which displays a giant St Leger Festival sign, and the words F18A - CodeHackCreate

     

    Game to be posted here later. :)

    I downloaded Wilhelm's XB Compiler from tigameshelf but it itself is a bin file. I'm unable to figure out how to open the bin in an emulator and I am in the middle of searching now when I decided to check back here.

    Assuming I get the compiler to work and I follow the only video tutorial on the topic, I should end up with a binary that still needs to be converted for the FR99.

    How do I do that? I'm looking to do that in emulation if possible since you mention I'd need 32k expansion.

    Assuming I can get all that done, do I still need a 32k expansion on the original hardware to execute my XB program using the FR99?

     

     

     

    The Compiler is zipped - that's why it's a bin file. In Classic99, look for the Arc303G ... you will have it in DSK1 folder. Now, select Editor/Assembler from the cartridge tab and use, I think, option either 3 or 5 forgive me my memory is hazy ... you can tell it DSK1.ARC303G in the input parser ... it will then run. Then you should tell it to unpack files that have a @ symbol on them. It will then spit out the files you need to get it all running.

     

    Or .... if you give me time, later on I will send some files that you need to put in DSK1 that are already unpacked. I'm not in the house at the moment and I'm on a chromebook. But i can help later.

    I was watching an older episode of Poirot where Doncaster was a potential murder location. I wouldn't have known the link to or 'significance' otherwise ;)

     

    Nicely done

    haha , yeah it's based on a real racecourse in Doncaster, England. I've done Arlington Horse-Racing, years ago, and thought it was time for a more advanced effort that takes advantage of some of XB256's extensions. :)

    The filename to load is MAIN3O .... that is with a letter O not a zero.

     

    I went into EA option 3 and it seemed to load something ... but not run it?

     

    When I say it loaded something, I mean I did not get any error messages. It just didn't execute anything and it went back to the filename input parser.

    Here is the 2nd revision of Doncaster Racecourse.

     

    It addresses issues I've found with the 1st revision, namely, the biggest issue - we can't win over $32,767 otherwise it will hit a minus figure. This one I should have remembered before releasing the game. :) ...... (I fixed it by giving less generous odds and having a $100 bet limit)

    The second issue to be resolved, was the random garbage it would display on the screen when a certain horse won in a certain condition. Being unable to find the condition OR the horse I simply re-wrote the whole win decider routine. That took 3 cups of coffee, an asprin, and 2 episodes of Doctor Who "Terror of the Autons" whilst waiting for it to assemble and compile across various stages of relentless testing.

     

    There are also some different little tunes in there. Tunes for race introduction and winning are chosen at random.

     

    Also, the scrolling has been fixed - the hedges in the far background scroll every 3 pixels and the far fence posts scroll 6 pixels. This is to give better illusion of realistic movement.

     

    My next revision, I don't know when, will fix it so that the game comes on TWO EA5 files instead of three! ... I know there's code I can tidy up, 3K of it is the culprit.

    There is another way, you could have 4 sprites + 1 set of 4 character patterns defined the same way as the sprites. Let's say that's the 5th "sprite" .... when it comes to moving, the first 4 would move as expected. The fifth one should 'become' a sprite (and the one next to become a set of 4 patterns) ... of course, you'd have to line up the sprites to the correct pixel line for the patterns otherwise it will stand out.

    Nothing modest about it. Found myself cheering my horse on, which is exactly what a horse race game should accomplish. Horse performance seems to be a blend of odds and random chance which is also spot on.

     

    The animation is great, and the graphics are quite pleasing.

     

    There are a few horse racing games out there for the TI (including a Compute! Xbasic type-in), but none of them ever had any replay value for me. This one does.

     

    Kudos. Well done!

    Thankyou Pebo! :)

    Thank you, I tried but the TI just re-boots. It looks like 3 of the files make up the E/A-5 part and I see a 4th file. What does that file do? Can it be added so that it will convert?

    The fourth file is a file that Classic99 and JS99er can use, it thinks it's a disk and just boots that one program.

     

    There's 3 EA5 files .... so try swapping them around and using just two ... normally there should only be two?

    I think some random part of another EA5 file might have gotten mixed in with them, unless it needs all 3 due to the memory (its 18K)

    Hello everyone.

     

    Created using XB256 and it's compiler, here is "Doncaster Racecourse", a modest attempt at a horse-racing game. Play solo or better still, with friends.

     

    This game is intended for use with the F18A board from CodeHackCreate, ensure the sprite limitation is switched off.

    Or you can use it in emulation with F18A mode on or Flicker Off. :)

     

    Changes:

     

    * Game now displays a random 'sponsorship banner' ... all name's you'll recognise
    * Parallax scrolling is now the fastest I can get it to go!
    * The music has been completely overhauled with a funky tune
    * Attract mode in title screen (after song finishes)

    * Background noise of crowd added (negative white noise so as not to slow game down)

    * Game comes on 3 EA5 files so people can convert to cartridge if they so desire

    Also created recently, a new plane bombing game called Agenda-99. 4 screens of action, compiled for accuracy and speed. Two modes of play, normal and insane. Press B to release bombs!

     

    This game requires the Editor/Assembler cartridge, loading uses option 5 and the filename.

     

    :)

    Haha .... yeah I should be calling it that!

     

    ......... I've been tinkering again ..... and this time, I have come up with a game that will drive whoever plays it utterly bonkers .... TEDDY has you attempting to steal teddy bears from a factory, you have to press SPACE to catapult the teddybear from the moving conveyor belt through a gap in the roof! ... This game is monotonous and hard but it does use a couple of XB256 features:

     

    Scrolling by pixels for the conveyor belt, scrolls 2 pixels per time two different ways with animated sprites for the conveyor belt wheels

     

    Use of the Soundlist Player thingy ... and it works very well! It's a bit complicated to follow but I got it in the end and the game has a continuous (short) soundtrack that plays uninterrupted in the background.

     

    Runs in XB ! Give it a whirl and tell me how annoyed you got.
