Whoops, no new game or update for our beloved GX4000 this last week-end  :picard: ? No matter, here is a little something to spend the week :

TOM & JERRY from Magic Bytes

TOM & JERRY 2 from Magic Bytes

I converted and uploaded the two games at the same time as they are very similar. Indeed, the second opus consists just in new maps on the very same average game. Personally, I played it a lot despite everything after having acquired it in a French compilation called Cartoons. And maybe someone else will like to rediscover this little game from our childhood  ;)

Quote from: Optimus on 17:47, 23 May 23p.s. Isn't it nice (even if lost that cycle) that this loss, ended up having to count NOP cycles instead of actual? Helped me a lot to easily sketch in my mind instructions from 1 to 6 NOP cycles,. be aware what's fast and what's to be avoided if possible, for optimizations.
That's true :D I don't begrudge the MSX guys for calculating their cycles in a more complicated way.
Best are the Enterprise 64/128 guys, which have "slow" (first 64K, shared with the video chip) and "fast" ram (>64K, Z80 runs at full speed) (like the Amiga).
As does the Speccy, though understanding it's contention behaviour (for the RAM that is contended) is absolute black magic. And different on different machines. And even different pages of memory on different 128s.

And it depends on how warm the machine is.  :laugh:

This sucks so much! >:(
I have no idea how this is possible with these 80ies pixel graphics...
Good, that you still have all the nice videos and seem to take it easy. I really like your mission to make videos of everything ever existed on the CPC, even the small things.
I agree with you 100% - any "problematic" videos should be highlighted individually & immediately to the YT channel administrator (IE me) with the option to delete them or to proceed at your own risk.
As I gradually (and slowly) upload the videos I've already made to Dailymotion I'll avoid most of those lovely French slideshows full of ladies.
Yes even the "small things" - the CPC was a 1st class (all round) home computer and there should be a record of the software that was/is available for it.
Bah Humbug!

The video is private, can you change paramaters to public view ? Thanks 😉
Changed :)

Quote from: eto on 17:40, 23 May 23Nice catch. Interesting that a malfunctioning 8255 can have that effect even if no keyboard is connected.
yes it's good to know
good after I did not put back the original AY-3-8912 because I had already mounted the SIL 2.2K with the AY-3-8912A / P
would like in case if someone has a link to find this part?
it would be nice to post it for others.
I took from an organ donor card :)

Oops,. other mentioned the same thing,. I think sometimes I ran on "AKCZUAHLY" energy :P

p.s. Isn't it nice (even if lost that cycle) that this loss, ended up having to count NOP cycles instead of actual? Helped me a lot to easily sketch in my mind instructions from 1 to 6 NOP cycles,. be aware what's fast and what's to be avoided if possible, for optimizations.
