Once upon a time, a bloke made a video about " Running PUBG on a 16-BIT Console? ".

I tinkled with this idea and made this proof of concept : http://sonicboom.fr/pubg.mp4

As you can see, there's a character with lines of sight, obstacles, and when reaching the obstacle, well the line of site is ...

I can't remember who (Chilly ?), but someone once told to send a small amount of data (circa 200B. I guess, this way, without the NOPs), then compute a checksum, and if the checksum is wrong send the data again.
That's the way I did it. Ugly, slow, so not useful.
#ItShouldNotBeThatHard ...

The only difference I spot is when clearing TE.
It would look like that when writing to CHCR, the common bits ($44Ex) must stay the same.
So, when clearing TE (aborting current DMA) don't do that:
SH2_DMA_CHCR0; // read TE
SH2_DMA_CHCR0 = 0; // clear TE
, but do this instead:
SH2_DMA_CHCR0 ...

Once upon a time, I happened to have these kind of strange behaviour.
I can not tell you my MD nor 32X model, not even MegaEverdrive version,
but I definitely remember reading unexpected bytes.

Could be / hope it only comes with the Mega Everdrive.

“The world has changed.
I see it in the water.
I feel it in the Earth.
I smell it in the air.
Much that once was is lost,
For none now live who remember it.”

I think we all see it.
You come and there's not a lot activity on this forum.
Sometimes a troll, sometimes a small question, but all in ...

Hello, and welcome to the scene.
I've written several thousands of lines of Genesis ASM.
I've always used snasm
You could find some useful links (and a great emulator too) here : http://techdocs.exodusemulator.com/Cons ... ment-tools

Thank you.
It is an actually much better way of posting this - still very interesting - piece of information.

Cheers,
Olivier

So many great new stuff!
It's nothing short of Amazing Vic.

I'm not sure the 32X had such a good year since ... 1994 ?!

True.
32X TECHNICAL BULLETIN #14 states :

In the 32X VDP, the shift bit becomes invalid when the lower byte of the base address set in the line table is $FF.
Therefore, make sure the lower byte in the table is not $FF when using shift

Hello to all.
I've tried to play with the DREQ_FIFO Register.
On real hardware,
It IS write only on the Genny side,
if 68S is not set, then the 32X cannot see it. The read value is always 0.
Thought that could help.

Slow clap

Thank you Sir!!

Take a look at my research posts about drawing sprites. There are routines that draws 32x32 sprites in various ways. It may give you some ideas.

But realistically chances are you’ll have to settle for a low framerate or draw just the important objects. The 32x doesn’t give you enough pixel ...

Once upon a time, Phil Lewin made an amazing Job with the unreleased Pinocchio : https://hiddenpalace.org/Pinocchio_32x_ ... prototype)

The 32x really has a lot to offer, 2D-wise.
Keep on the hard work

... or macro 'em.
I think I remember some assemblers had some problems with MOVEP.
But we're talking 15+ years of memories
