Re: introducing myself
Hi Martijn, Nice to see someone else who is starting from scratch and learning something entirely new to them. I do have some previous experience in web coding languages, so that sometimes helps me. Although, learning z80 ASM is quite the different language compared with PHP and MySQL. I look forwar...

Re: Changing Hex in memory to Decimal on screen
I found the issue!
wait for it.
there was a missing ret command..
so happy to have found it.
Was just doing a bunch of break points and watching the program counter.
whilst thinking about this issue I thought of a few tweaks I can make to my code to make it quicker too.
every cloud.

Re: 68k asm tilemap data to Z80
Not a genus programmer yet able to learn ASM for so many cpu's.
Keep up the good work. Your help is amazing. if it wasn't for your videos and forum, i'd never have gotten started in learning z80 asm.

Re: Changing Hex in memory to Decimal on screen
Thought i'd post a little on what I've been up to to try solve this without BCD. Every time I tried to watch the video you have on BCD it turned out to be very late and I couldn't concentrate. However, after sleeping on my issue I came up with another solution (I thought). This was to do some >= sta...

Re: Changing Hex in memory to Decimal on screen
Thank Keith,
I'm watching your bcd video now. Hopefully i'll understand that and be able to use that to fire numbers on screen.
although i'm not sure if that will cover the printing of each number.
I'll let you know how I get on!

Changing Hex in memory to Decimal on screen
Hi folks. I'm looking at my ASM code again and have came up against my next great challenge. Showing numbers on the screen in decimal even though the numbers stored in memory are in hex. So I'm making labels like so: ;days dayDate: db &0b monthDate: db &04 yearDate: dw &0c73 which are go...

Some more Newbie questions
Hi hi. It's been a while since I had time to even think about the program that i've been "writing" for months (aka. doing a few lines then putting it away for a few weeks and then coming back to it and doing a few more lines. Over and over.) I'm looking to draw some images and have managed...

Re: Just saying hi..
Hi Nick, Nice to see more and more people joining Keith's forums. Isn't he a gent for setting all this up! I seem to have a similar feeling on working on these older system. I love trying to make things work on them when they are so limited (compared with todays computers). Yet people can still make...
