Re: what should i write next?

So, when is the C64 emulator due for release? ;) I did think about it very briefly but couldn't understand the video modes in enough detail. And I got rid of my own C64 ages ago without ever doing much with it. From my limited understanding, I thought the sprites would be a problem without some ser...

Re: Morecambe & Wise restored using BBC BASIC!

Great stuff - I'll be sure to tune in. I recently read a fascinating BBC R&D blog about (I think) some other M&W episodes that "survived" on a really badly damaged roll of film. The film was too badly damaged to play but they were able to recreate frames without unwinding the film by using x-ray ima...

Re: what should i write next?

Excellent - very smooth =D> =D>

I've only just sorted out the palette change interrupt stuff on my Beeb CPC emulator and so have been playing lots of Pacland today. The lack of scrolling on the Amstrad version is *really* annoying as you can die by hitting a car that you can't even see! :x

Re: what should i write next?

I've been looking at Pac-Land and although I can't get very far and haven't played it much, so have no idea about secrets etc, it does look like it might be OK. The sprites look scarily big though, so I think a prototype is in order! It seems to run perfectly well on my CPC emulator but that is usi...

Re: Mode 128x128

Essentially I'm after the smallest size with 16 colours (or 4 at a push). It seems therefore that Mode 8 (horribly wide pixels) from the AUG is the safe minimum. If you don't want to risk things, it's entirely possible to reduce the number of vertical pixels safely as you just reduce the value in t...

Good to hear you're still working on it.
Did you use Mode 5 or 2?
Do you have any videos or demos available?
It's mode 2 with background graphics by the very talented John Blythe. I've attached the latest stable version (no enemies but all the levels).

This is mitigated by using the PRES E00 ADFS, which runs from sideways RAM. That leaves all your memory there, *but* it won't work with a SCSI disk.
I've definitely used some version of ADFSE00 with a SCSI drive on a Beeb (actually B+) - it was possibly this one.

Thanks Simon. I take your point about the risk of damage - my plan had been to look at getting digital audio out of my 410 before risking the 415 but the 410 obviously doesn't have the decoder board so would require more work.

Worth a try -- especially as the signals are handily available on the connection between the LV-ROM decoder board and the CPU data grabber board… I've ordered a couple and will report back when I've tried it out. I guess the only thing that might stop it is whether there are any differences in the ...

I've seen something similar to this with a low voltage Master PSU and adjusting the pot made it go away. Can't remember if it was only in mode 4 though (think not) but it was definitely coloured speckles on the screen.

I've always understood that the LV-ROM data and PCM audio data are encoded in an identical fashion… This seems to be corroborated by the photo of the LV-ROM decoder board on Domesday86 , which is using Philips SAA7010 and Philips SAA7020 chips to demodulate and decode the data.
