Re: Fast PLOT routine
I could write a lot on this subject, as many of my ZX81 games - especially ZXagon - need to do this. I’m pretty sure I could write a faster routine than the one mentioned here, but the real trick is to not do it from BASIC, so you can use a custom back buffer format which suits the kind of graphics ...

Re: Bobs stuff is down
Hi all! I'm really amazed/touched that anybody noticed! It wasn't planned - there's been a problem with renewing the domain which wasn't noticed until finally 'hit' and went offline. Hopefully everything will be back as it was soon, but I also have a contingency plan if that doesn't go to plan (Unti...

Re: CroZXy Road - New 16K ZX81 game
Thanks dasteph & kokkiklhs , it's always really great to hear back from people who play my games - otherwise I'd think nobody cared! You're exactly right dasteph - one of the reasons I converted this, and ZXagon (see Super Hexagon) before it, is to prove that there are some great modern game ideas w...

Re: ZXpand ROM character set corruption
That sounds like a simpler solution to my problem Mark, but would the joystick interface still be available to me? That's the only functionality of the interface which is used.

Re: ZXpand ROM character set corruption
Thanks Siggi, that makes sense. Hopefully I can find enough memory to duplicate the font into RAM for the affected games.

Re: CroZXy Road - New 16K ZX81 game
Looks like there could be some graphical corruption when the game prompts for initials for a highscore and the ZXpand interface is used. The game itself will continue to work correctly, but your position in the highscore table, and the initials you enter, will appear as random blocks. I'm hoping som...

ZXpand ROM character set corruption
I've just released 'CroZXy Road' for the 16K ZX81, and somebody has mentioned that there is graphical corruption when a ZXpand interface is present. This has been seen when using the EightyOne emulator, and I've narrowed it down to my game reading the font bytes from the ROM address 0x1E00 forward t...
