Anyone done this yet ?

I've playing with my 6502 system for a while but it's time to get back to the Hydra...

My first game "Mercury Mission" was pretty much just an exercise to get up and running with Spin.

I want to learn how to write my own driver and renderer for NTSC so this time I guess I have to tackle Assembler...

Guess one good start is the "SimpleNTSC_256x192_256_colors_002.spin", it's pretty basic...

Living on the planet Earth might be expensive but it includes a free trip around the sun every year...

Experience level:
[ ] Let's connect the motor to pin 1, it's a 6V motor so it should be fine.
[ ] OK, I got my resistors hooked up with the LEDs.
[X] I got the Motor hooked up with the H-bridge and the 555 is supplying the PWM.
[ ] Now, if I can only program the BOE-BOT to interface with he Flux Capacitor.
[ ] I dream in SX28 assembler...

Hi Bamse, i did a rubbish version of spacies, while getting started with the prop, so be my guest and do a decent version, as it'll save me a job of re-doing it now I know the processor more :)

oh and SimpleNTSC_256x192_256_colors_002.spin is a great starting point, but will remove any option of a PAL version. guess I really must have a look at converting that to PAL some time, when my to-do list is small enough lol.

Well, Space Invaders is going to be my next project then...

The NTSC_256x192.... was a great help for me to understand how to generate a page.
I still haven't figured out the itty bitty details but I managed to understand the principle...
The calculation on what to put in the VSCL and Waitvid is still a little bit of a mystery to me...
Just need to stop playing Frogger and Unterwelt and get back to the code...

I do agree that it would probably not be a good starting point since it's NTSC only, but it really helped me getting started...

I might just scrap the Space Invader idea for now...
Hope I don't disappoint to many people...

Another game just came into my mind, Jeff Minters GridRunner...

This is one of my favorites and I think it would be much more fun for me to remake this game rather than Space Invaders...
Guess I have to start up the C64 emulator and get some inspiration...

Nah, I won't be disappointed GridRunner will be a nice replacement :) go for it!

I wrote a clone of that for the Atari 800 when I was going thru my "TRON" light cycle game programming phase, definitely more to do than space invaders.

There is hope, I found the font by doing a memory dump from VICE...

The mapping is a little bit weird, but hey, it's a game, not a word processor...
All 64 chars have been added to the Video Driver...

Not much progress, been busy this weekend with "real" work...
At least the main loop is there, but not much else is done...

I think it's time for some "inspiration" and start playing the game in Vice...

Howdy, been a while...

But the old shed is torn down, the dogs got a new dog run and the gutters are cleaned...

I also found a couple of LCD displays that I had been looking for and finished up a couple of projects for my Replica One, a 6502 system...

So it's time to get back to Gridrunner...
Got the missile to shot and some Centipedes running all over the screen...
I also need to start looking into sound effects, it's pretty boring without sound...

The whole weekend is booked up for a family event so I wont be getting back to Gridrunner until Monday...

Finally, I got rid of that annoying little bug...
Did anyone notice that the centipedes where turning a little bit weird when climbing up ?

I guess this was due to a conversion problem between bytes and longs.
I eliminated the use of -1 in my array of bytes and now it all works...

I know it's been a while...

But this project is not dead yet...

Got the side swipers to fire and also the bombs to work.
Still a lot of work to do, but slow progress is better than no progress...

I just tried this for the first time and it is pretty sweet. I like the intro with loader screen from the C64.

Keep up the good work!

Added a bunch of comments, hopefully the code can be understood by others...

You can now crash and the lives are counted down, the scores can be set, they are no longer hard coded...
Time to start working on the actual game logic a little bit...

And maybe even add some sound...

OK, one more thing before I can start working on the logic...
I need to figure out how to split the Centipede...

But that seem to be a task for the weekend...

Looks pretty cool now that the Centipedes actually turns...

By the way, does anyone want to help out with the sound ?

Getting better...

The look and feel is pretty much there...
Finally got the Centipede to split properly...

Hey Bamse, how's the project going? Started working on the logic yet? I'll add your project to the master index when it becomes generally playable.

Well, it's going pretty slow as you might have noticed...

Anyone up for helping me out with sound effects ???
Currently that is the biggest hurdle...

I think epmoyer was the one that would volunteer for those tasks, but he seems to be missing as of late.

Believe it or not, I'm back...

I got a basic sound effect engine running using the Hydra sound drivers.
I'm not really happy with the sound effects but at least they seem to work so I'll get back to them later.
Time to work on the game logic a little bit more and clean up the code.

Bamse, can you post some screen shots as well, it gets people to download more since they can see what it is.

Yes it's pretty hard right now...

I would imagine this would be Level 20 or something...

That will be the weekend project, to start at level 1 and get harder and harder up to this level...

Here are some "screenshots", I will have to convert the driver to allow for that screen capture tool that is available somewhere...
I'll try do this once the game is done...
