It may be so that the articles are written using a bit of AI help. Then edited by human hands.
(There are many copyrighting tools: copy.ai etc..) That may be why the copy is somewhat tasteless and missing some information here and there.

There's also a slight difference in LD A,R/LD A,I behaviour according to @arnoldemu

But SymbOS working 

Thanks, yery good to know!

SymbOS is using LD A,I/LD I,A a lot, so this part seems to be 100% the same for both Z80 versions.

According  to that thread it's a bug on the NMOS version only where the P/V flag gets cleared if an interrupt occurs while processing one of those instructions. I imagine caring about that is such an incredibly niche situation that nothing would be affected unless specifically testing for it.

I will be making a hardware patch in an inelegant version, i.e. shorting D0-7 from high to low. If anyone knows whether the CMOS output can withstand such frequent treatment, please write something.

Technical support - Hardware related / Re: cable DDI-1 for CPC 6128

Last post by Rabs - Today at 06:19

Isn't the DDI-1 wired to supply 5v on the floppy cable?

Could that damage the CPC?

I read this also somewhere, not sure if it is correct but as I am only using with a CPC 6128, I disconnected the internal 5V supply just in case I initially got the cable upside down. Guess I can reconnect now it is working.

I read through the SMS one as well; I quite fancy doing a SMS game sometime. Looks like it would be a piece of cake, although all access to graphics RAM having to go through the VDP is a bit of a shame. No wonder all those games that tried to do software sprites on the tile layer (like you would expect from any good British coder) had a hard time. 

Looks like a nice site. It's all laid out and written very clearly.

Next steps:

• add enemy bullets/collision detection
• game over splash
• music/sfx
• extra graphical touches and effects
