Re: BASIC Space Invaders

That's not very good :( I did make a last minute change to add the loading screen, it looks like the cleared bit is where it changes to mode 5 before changing to 256x256 mode 1. My guess is that my CLS code isn't working, but I'm not sure why. I would guess a quick fix might be to add a mode 1 befor...

Re: Hello from 45 degrees South

Welcome, I've seen the guys at the ABUG meet-ups bring one back to life and fix minor faults on others, but it does seem to involve oscilloscopes.
Good luck with the Doomsday, i hope your discs haven't rotted too much.

And you can access the clamps to release them, but I doubt that they will fit a Master (I haven't checked ;))

No longer BASIC, just basic now, but apart from screen memory access, it should be OS friendly.

Re: BASIC Space Invaders

Thanks, space Invaders wasn't one of my favorites either, but it was my first, and always there. The only two things that are really different now are emulators, allowing more advanced debugging and a better understanding of virtical rupture. The only thing that i regret is that Gil and I never fini...

I have the original sound, but it is proving very hard to reproduce with the beeb's sound chip. My partner asked me why I didn't just download a WAV and play that :roll: I may actually have to do that, although it would go against trying to make an OS "legal" game (apart from screen memory...

Really enjoying this, I can clear the first level without missing a single "nasty", but haven't killed a single one on level 2.
I guess I need to go and study the shield/health stats a bit more.

Re: BASIC Space Invaders

Can anyone think of a beeb game with an appropriate sound effect for the firing noise in Space Invaders? Any game on any platform using the beeb's SN76489 will probably do. I tried for many hours to get the high pitched whistle right, but just couldn't do it (sound is definitely one of my weakest po...

With the space Invaders http://stardot.org.uk/forums/viewtopic.php?f=1&t=12474 digression nearly done, I've been thinking about a platformer framework as take-up of my sprites http://stardot.org.uk/forums/viewtopic.php?f=53&t=12565&hilit=sprites+framework#p161873 wasn't stellar​.

Thanks, i think that is helped, by being in mode 1 with palette switching giving more than 4 colours. For this game, it doesn't do any tricks and even the font is just the beeb font shifted one pixel and anded with itself.

When you say updating the display while debugging, do you mean showing what would be on screen if the change to memory had been scanned out?

I made them like this as I wanted them to be as small as possible, not to have wires floating around for shows and I don't need to change the cards very often.
