    Hello, I just tried one of my old VIC-20s and it freezes when trying to boot up into basic. It will however play all cartridges that don't boot to the prompt.

    So all games appear fine except for adventure games that start with the cursor prompt.

     

    Any idea what has went wrong? Is this likely a memory thing, or something wrong with the ROM?

     

    Is this a common issue?

     

    Any help would be appreciated.

    I might actually look into this, would be an amazing learning process. Gonna need a lot of help though :)

    Let me know if I can do anything to help with a Vectrex version.

     

    Although using the 'normal' ROM object drawing routines I was pushing it to make Vec Wars and Circus Vectrex!

    But I did manage to do Spike and the argry Vortex Bird by mostly drawing lines directly to the screen, and not using the object draw routines.

    The grid lines constantly move forwards in this, and the walls and diamonds also move towards the front of the grid, making a pseudo 3D effect. All these are drawn to the screen using direct lines, with the Spike character using the draw object ROM routine.

    Just wanted to say I've stopped working on the initial version of 'Vec Wars,' and 'Spike and the angry vortex bird (thing)' now, but thay are still available from my blog page.

     

    If anybody is looking at making another Vectrex multi-cart please feel free to add these if you like them.

    They are now both full games that can be played through compleatly, with no glaring game-play bugs that I have found.

    Yes, I'm from the UK.

     

    As I said this isn't so much a collection as what I have left over from when I bought them as new.

    We had a lot of budget 8Bit Atari titles in the UK. With most full priced software coming from the states.

     

    I think Draconus was a full priced UK game though, although I could be wrong.

     

    I also found 4 8Bit cartridges (StarTrek, Missile Command, Star Raiders, and Super Breakout - all unboxed),

    and also a bunch of UK Atari User, Page 6, and the later Page 6 Atari User magazines. Around 40 in total - most in good condition.

     

    I will have a look in the market place, thanks.

    Thanks, hopefully I just have a bit of tidying up around the edges of the graphics and movement routines to do, and hopefully put a popper tune on the front screen.

     

    I will release the binary, and/or rty to get it added to a multi cart... so if anybody is interested let me know...

     

     

     

    I do want to try and make (literally) two or three cartridges of this one, complete with box and overlay just as a bit of an experiment, but the cost is high!

    I am writing a game for the Vectrex that is based on Circus Atari and was going to try to convert the 'Entrance of the Gladiators' music for the title screen (using VECSOUND). However I can only find this in tune in SNDH format and not YM.

    Is there any way I can convert an SNDH file to a YM file using a PC? VECSOUND only converts YM files to Vectrex code.

     

    I believe you can do this on an ST. Unfortunately an ST is one of the systems I don't have.

    I've just uploaded the latest version of the first VecWars to my blog (http://garrysgamingblog.blogspot.co.uk/p/programming-projects.html).

     

    This has a few bug fixes, and some changed game-play changes: mostly the addition of an energy bar, that limits how long you can hold the laser button down for. It also has rudimentary sound, which would need some work before the game is finished. But from this I hope you can see my idea for the finished

    game taking place:

    I always wanted an Atari console :( but only had a Teleng colourstar (now that was a rare console). I remember playing on a console at my mates circa 1982 that seemed advanced for the time. There was an invaders game that had about 128 variations including swerving bullets and a golf game. There was a soccer game that had offside (unusual for the time). I think the console had numbered keypads.

    The fist TVGames system I ever got was a Teleng Colourstars as well :)

     

    They didn't really call them consoles back then... It was out a few years before the VCS though!

    The same console was produced under a variety of names, if I remember correctly.

    I've been working on adding shooting and explosion sound FX and I'm looking at adding a random respawn - based on moving the player away from other objects.

     

    Above this I'm looking into allegations of the game crashing when played for a while, and info or feedback would be appreciated.

     

     

     

    For the second one, I think I've found a way to get that bit more on the screen without causing too much flickering, although I havent run these tests on my real Vectrex yet. I was also playing with the idea of using bullets instead of the laser... Although I do like the simplicity of the laser.

    I may have written some similar code for Spike and the Angry Vortex Bird, feel free to give me a shout if you get stuck and theres anything I may be able to help out with.

    I think something like the Atari 2600's Robot Tank should be doable, with relatively simple scalable pre-drawn shapes.

     

    The Vectrex can draw lines relatively quickly and it can rotate and scale pre-designed shapes relatively quickly, but it does suffer from a fair bit of flicker when doing the maths and the drawing in real-time.

     

    I got quite a lot of big-object movement into my Spike and the Angry Vortex Bird game by using direct line drawing (and some creative maths) to move the background, but what you see there is about the limit (drawing-movement wise) that I could fit on the screen.

    I don't know if anyone is interested or not, but I'm looking at starting a VEC-WARS 2 game, based on my (almost finished, but now old, and previously abandoned) VEC-WARS game: See -> http://garrysgamingblog.blogspot.co.uk/p/programming-projects.html

     

     

    Much to my surprise I recently found out that this had gathered a bit of a niche following, and I was asked to finish it - which I am currently working on. This was when I started thinking that it could be improved with a re-make. So I'd be interested in seeing what people think works and dons't work from the origonal, and what you would like to see added.

     

     

    Please remember that this is a real project that I ideally want to make into a game worthy of release on it's own cartridge, so nothing too starry-eyed. But all suggestions will be read and considered.

     

     

    Thank you for your support.

    I didn't know it existed untill after I wrote this. The other version is much more polished, and much closer to the original gameplay.

     

    Mine was just a quick five or six hour effort over three and a bit evenings, which was done as a bit of fun.

     

    I suppose I could tidy it up a bit, rotate the bird, make the graphics and animation a bit better, although I can't stand the original button controls, I could introduce a bit more movement controll. Although all gap combinations are reachable.

     

    Or maybe I should just turn it into Floppy Fish!?
