Re: Lode Runner on the ZX81?

To print 109 to the screen without getting "?", you need to poke it to the Dfile.

05 rem print to the first character space on the screen
10 poke peek 16396+peek 16396*256+1,109
20 print peek (peek 16396+peek 16396*256+1)

The idea would be to poke the entire active level to the Dfile.

Re: Lode Runner on the ZX81?

Wow Dr Beep, you're getting some serious compression going there. I think 32 levels might prove to be a comfortable target. It's a nice number and equals the total available on the Vic20. My thoughts on level design graphics wise are: If that's chr 8 then that's good for standard bricks. This means ...

Re: Lode Runner on the ZX81?

The level compression really is one of the major keys to Lode Runner, being an entirely level driven game. Not cramming in enough was one of my concerns. I'd figured I'd need to make a least 10 levels available to make the game enjoyable and playable. So, not going out on a limb here to say that the...

Re: Lode Runner on the ZX81?

Hi Dr Beep. Yes that's my page and musings on Lode Runner. Would be more than happy to have you on board the project. I've been a little distracted by other things (like ZXpand Mice) over the last month or so, so not had a lot of time on the project since that last post. So yes, very keen to hear yo...

Re: My new baby!

@ moggy All aluminium (I'm rather further and across a much wider pond), talk about spare no expense on the memotech cases, wow. @ sirmorris What ever works best for your design of course is the best solution :-). As the box header is through hole, it's no issue to add internal connections if one wa...

Re: My new baby!

I like the last (I just had an idea) idea the best. If you take that option would it better to then use a right angled pcb mount db9, if that fits on the PCB? The trouble with the box header at the end of the board is that the externals become messy. A ribbon cable with a bd9 connector attached to a...

Now that is a good command to know "CONFIG "J=UDLRF"". 😁

Re: My new baby!

Congratulations, nice work. If there is a list count me on it. 2017 seems to be the year of the expansion, with the ZXblast and now the ZXpand+.

Re: Composite to HDMI Converter

For PAL, be careful with any converter that only lists PAL M, PAL N. Ideally you want a device that specifically states PAL B and PAL I at the very least. That counts out most of the cheep Chinese ones on Ebay. I've not tried and composite to HDMI converters, but numerous composite to VGA converters...
