Re: New version of Scramble for the beeb (going well)

I have been feeling a bit better yesterday and today, and managed to add bombs to scramble. I still have to tidy up collision detection or something for bombs and shots, but it's getting there. The video capture is a bit dodgy as I had to use b-em + VirtualDub on my stuttering PC! https://www.youtub...

Does your image work in beebem or any emulator for that matter? You can get it in the thread linked above.

In my video in that link, you can see that I barely get it and I think I only have one or two ram chip failures!
It is only on while the keyboard LEDs flash, then swaps to mode 0.

Re: Wanted: Acorn machine

Model B is probably the cheapest least expensive "beeb", but it is a little large for carry on (doesn't play PoP). A master compact is about the smallest beeb, but also the most expensive and a bit less compatible that the others. Adding an MMC is a few pounds if you do it yourself, although I would...

I played it in the arcades (if it was the same game).
I don't remember it being mentioned at CA in the 14 years that I was there, but it was 10 years before my time. I can't see which versions were done there, but it was probably Tim Ansel.

Re: 640x512 50 fps Bad Apple on a B... how?!

I know it doesn't matter here, but you could detect that you were going to run out of time and leave any bytes only Changing 1 bit until the next frame, prioritising ones that have several similar neighbors.

Ps prioritising ones means picking them first for deferring.

Looking very good. Are you heading for a straight race like sprint, or more like simple Mario cart? The tube certainly gives it a unique look. Is two player simultaneous an option? I guess that would make controlling the ship even harder. Or even linking two beebs? Would it be more playable if you b...

Re: Well Hello!!

When I was a teenager, I did a distance learning course in COBOL.
We had to write our code on coding sheets and post it off, where it was punched on to cards and fed into a mainframe.
We got quite a few syntax type errors and round trip on compilations was about a week and a half!

I wasn't being negative about how a game is selected with a GOTEK (I've just ordered one for myself).

Re: Well Hello!!

The gotek is good for a smaller number of disc images as swapping is about the same as changing a real disc, including finding it in the box (selecting it) and is probably the most compatible disc substitute. If you don't have a disk interface, for about £12 you can get a ready built MMC (I think fr...

As you can set the palette and then run any existing game, everything is supported.

Re: How far gone must a BBC be to be unfixable?

For me, if the PCB was gone, I would probably put in an FPGA with options to switch between different beeb models.
This would be more useful for me and as I have quite a few "real" ones, I would feel OK.

I hoped that it might work as the converter will clean up the signal colour, as long as the timing isn't affected too much.
