Wow! That looks much nicer than my version. You added more detail to the text - I wonder if I can do that without making the data requirements too high.

Thanks for taking the time to add that information, Kees. I may add captions to the pictures.

Did you get your Python installation working on Windows? Sorry I had to leave at around that time - I had to visit some shops before they closed.

Thanks for the write up. At this late stage, I should say that I was really impressed by the GUI stuff done by Kees, and especially with the integration with the buttons and LEDs and things. I'll have to get my photos uploaded at some point and break out the Atmel gizmo I picked up in Britain!

Re: Tetrapod!

The original Star Swarm game didn't have bullets that bounced off the walls of the arena, so it is slightly easier, I think. Both versions should be available in the STH archive.

Re: Games you'd have loved to have seen converted

I'm slightly confused. Why couldn't you do 2 way, non-forced scrolling with this method? Is it because the bank switch is linked to the scrolling effect?

Re: Games you'd have loved to have seen converted

I thought I saw a video of the Amstrad CPC version of Twin World on YouTube but my search skills are failing me at the moment. It looked OK, anyway.

This video of Edge Grinder shows off some better scrolling on the CPC. I imagine it uses all kinds of tricks to get it that smooth. :)

Re: Games you'd have loved to have seen converted

I'm thinking of games that might have been implementable, but were probably not done due to commercial constraints, like Rescue on Fractalus! and Zarch/Virus.

I liked Ranarama when I first saw it, too.

Re: Games you'd have loved to have seen converted

I always thought a cut-down Alex Kidd In Miracle World would've been a good candidate for the Beeb. I always had it in my mind for a conversion - we can do the smooth vertical scrolling like at the beginning of the game, but the horizontally scrolling bits would let it down I think. The Beeb can't ...

That was quick! :D I hope it still works.

BT Merlin amber monitor

Some time ago, I discovered the Acorn Electron World articles about the Merlin M2105 . The user guide was particularly interesting because it possibly explains the origins of the monitor we used to use for our Electron. The monitor was a Watford Electronics refurbished job, badged with a BT logo, an...

I hope I'm not jumping the gun (in case the author is preparing to post on here himself), but did anyone else notice this YouTube video of an unreleased BBC Micro game, called Zen?

It looks pretty good! Definitely a candidate for a Retro Software release, if you ask me. :D

Re: Electron Game Cartridges

Looking at the code, I don't see an obvious way to specify two ROMs for the same cartridge. The readme.txt file indicates that the two ROM files for Starship Command need to be loaded in separate cartridge slots. Is that because most cartridges used only one ROM slot, supplying 16K, but could be wir...

David - I guess you're looking at an NVRAM capability? I have previously used various Maxim devices but they're internally battery-backed and not true flash ram.

Re: Electron User Port & Rom/Ram board

It looks very promising! I've been hoping to make progress on a simple ROM cartridge board of my own, but it's the usual story of trying to do too many projects at once. Perhaps naively, I wanted to use flash memory in place of ROMs. What are the chances of having these devices working on the board?

Re: Wanted: A5000 Alpha FPA Chip

I have vague memories that my A7000+ performed as well as a StrongARM RiscPC on some benchmarks precisely because they were so floating point intensive. It's a real shame that the SA-1500 never made it into a product.
