Re: Reading Keyboard ports on Next?

Reading the keyboard via the ports is just like the original speccys. The ports and bits returned are in the manual. Page 264 has a list of the ports and for the joysticks page 273 explains what each bit is. Thanks. It was my mistake. I imported my old code, but failed to make a 'call checkkeys' in...

Reading Keyboard ports on Next?

Hi all. I am just starting to learn Next development in assembly. I have drawn and moved some sprites, but my existing 48k keyboard code seems to not work.

hi em00k I finally got my Next dev environment set up, and found your excellent sprite editor tool. However I cannot tell if I am able to draw (and generate in ASM) a sprite larger than 16x16. The hardware deals only in 16x16 sizes but it also allows these to be joined together (called composite fo...

Saying hi

Hello fellow Zediots! :D I recently got back into retrocomputing after many years of not exploring my interests (although I have of course always enjoyed retro computing in general and got my first ZX Speccy at aged 4 in 1986 and never looked back haha) Just saying hi really! But also letting you gu...
