Re: New Game: Ringo (128k)
So I am guessing the screen contains set block graphics, E.g. 11110000 11110000 11110000 11110000 Etc And then you just update the attributes on each swap screen, I imagine one paged in at 8000 and you alternate the addresss between 5800 and 9800 when you write the attributes Then do some clever ras...

Modern Sprite Editor
When I developed Bipboi in 2006/7 I used SevenUp to do the sprites as I loved the masking functionality, export etc
In 2022, is this still the go to sprite editor for the Speccy or would you have recommendations for an alternative?
Thanks
Rob

+3 Drive Problems
Hi If I format a disk on my +3, I can read and write to it no problem, however it doesn’t read any other disks, including commercial. I am using a modern PSU, not the original PSU that came with the +3 Could it be that the motor is running but not at the correct speed due to power, or is that imposs...

Re: ZX Spectrum 128k 40th Anniversary?
Thanks Juan, This is amazing, really helpful thank you, So we know it’s September for the launch, and October. Out of interest, September 25 was a Wednesday in 1985 so I wonder if it was the previous week. For any non Spanish speakers (like me 😁) My Apple translator roughly translates this as: “ One...

ZX Spectrum 128k 40th Anniversary?
When is the official 40th year anniversary of the launch of the 128k Toastrack? I know it was launch in Spain first so the backlog of Spectrum+ could be shifted in UK, but the 40th anniversary sounds like a good target for a 128k anniversary Dev project, assuming it will be in 2025.

IM2 Timings
Hi I am experimenting with timing from when the IM2 Interrupt fires until the first display byte, 16384, is reached by the raster. From experimenting using the ES Emulator, it appears that the IM2 fires at 0x13 (TStates) on a 48k Speccy and 0x1D (TStates) on 128k. Is this documented, verified anywhe...

Re: Double buffering on the Spectrum
Cobra This one is more complicated - there is no background buffer; the scenery is redrawn from scratch each frame. There are a very limited number of scenic blocks, but it's actually quicker than a scroll+copy. Note also that the scenery now scrolls in 2-pixel steps. The pre-shifted scenery blocks...
