When you change from ide to sata there’s a completely protocol change.
IMHO much better to use ide to cf adapter, in this case I suggest to use industrial Cf cards.
I’m waiting for this solution to came from china, I ordered it on AliExpress.
Prices are quite cheap.

@Mikey_C

Because you don’t know “Fiat Duna”

Thank you I can give it a look.
Really I was looking for something much simpler, without use of SDL. Is there any other spot?

Hi Guys, I'm looking for a fast and simple fading effect for OS4 and 24bit ARGB screens.
My primary goal is a "fade to black" effect but as second option a "fade from black" is welcome too. I'm looking for some C code already done to adapt in a fast way. Tnx!

@walkero

Do you think LTO optimization can be enabled for GCC native builds?

@rjd324

LOL!
Anyway it's a must to have native modern/full working compiler solution on Amiga.
Maybe your experience can be helpful for next SDK release.
Thanks for sharing your experience.

@salass00

Ok thanks!

@kas1e

IMHO GCC 8 should not have SPE support, it was lost after GCC 5
Is there someone to confirm (or not)?

@walkero

Glad to know you are involved in this project 🙂
Is there any chance to have a native support also for A1222/tabor? GCC needs a patch to support also spe code generation.

Actually I'm using unofficial GCC 8.4.0 installed over original OS4.1FE SDK
In next days I'll update with recent Hyperion SDK release.

What GCC version will be included in next AmigaOS SDK release?
Is It possibile to upload a full version of GCC on os4depot and/or aminet?

I'd like to be present (4 PM local tima - Italy).

@BSzili

You could unroll loops blit_height - blit_width if multiple of 2 (or 4) and gain some minor speed.
It could still entirely fit in the cache.

My2Cents

Very interesting, very nice presentation. thanks 😊

To test FPU emulation Flashmandelng could be a good candidate
Maybe we are in time for an A1222 specific version too, it only needs to be recompiled with right GCC version.

Probably I suppose it's only for AEON's motherboards.

@trixie
I don't know, anyway I could be interested in an evolution of os4, EnancherOS or PippoOS is the same, name really doesn't matter.

I really don't understand why force these overwrites of system components now, anyway I don't want repeat myself again.

About MorphOS I use it too and it's really a great OS! ..so it should be a valid future viable way for amigaos platform.

It's absolutely clear to me when exec-sg will be done we could have a new EnancherOS with all remaining parts owned by Hyperion replaced.

It can make sense in a next time, but now why do it? Are there some hidden messages to Hyperion?

Amiga community needs more clarity, we don't need obscure plans. Thanks.

@Capehill

Maybe with OS4 default datatypes you can’t save in all picture formats because there’s full support only for load.
Use iff ilbm format, it’s our standard for pictures.
We are amigans we have our peculiarities

@Capehill

You can use this to save an ILBM or change it for PNG.
Why not IFF ILBM?

@broadblues

I have modified code to try to implement custom chunks as suggested by Edgar, iff file is saved but opening it with an editor does not show presence of desired informations (custom chunks)

Here is my code, please look at followinf line

SetDTAttrs (o,NULL,NULL,DTA_Data,"***dino***",DTA_ObjAuthor,"***pippo***",DTA_ObjCopyright,"***pluto***",TAG_END);

it should do the trick and I added some different tags just to test, but nothing hoped happens.

Maybe it's a not fully finished impementation of iff datatype library.
