Managed to assemble and run the RAXOFT tests in my emulator last night and discovered that the main reason why the series generator wasn’t working was the SRA instruction. I wasn’t preserving the carry bit. (ANDing it back into bit 7 rather than ORing it). Job’s a good-un.
Loving this C64 easter Egg that someone at TT Games put into the new LEGO Batman game. I'm not sure who it was that did it, but I need to find out from some of my former colleagues! If you know please do tell!
One more to celebrate my old mate Colin Porch’s sequel to Head over Heels - Return to Blacktooth. Released last week by @thalamusdigital.bsky.social
Two-player #BBCMicro Elite now has a two-player dashboard
Each player has their own set of indicators: speed, attitude control, fore and aft shields, laser temperature, energy, missiles and compass
They share the scanner, which works well
It’s starting to feel like a proper game!

Did you know that Super Mario Bros 2. on the #NES had a bug where a single bit in its code was accidentally set to 0 instead of 1?
Well, this little oversight resulted in the 8th frame of many animations in the game getting skipped over

Some tweaks to the emulator this afternoon. The port decoding has been moved out of the cpu class to make the Z80 generic. Added BRIGHT attribute. There’s a bug in the emulator that’s causing issues with some calculations. I think it’s manifesting itself in the series generator.
If you are free tomorrow do you fancy a visit to the Northwest Computer Museum to help them celebrate their 3rd birthday? Entry is free and there's so much to see and do. I hope to see you there, please say hello if you do! It's located in Leigh, near Manchester. Here's a flyer from their socials.
