AGA/OCS (planar) vs 8BIT CLUT (chunky)

Friday after work, and yester day I did some experimentation, people keep on saying how great AGA and OCS are for demos, is this really true? Does planar really have a advantage over 8bit CLUT chunky graphics. I think it does not, its just that planar modes, makes easier to do layering, and graphic card does the rest, so my experiment was simple implement some sort of layering in 8bit CLUT, should not be too hard.

So here is my main code, not so complicated.

Α600: Final overclock. ACA630@37.5MHz

Hey peepz.

As I said in previous articles, my ACA630 was unable to operate stable @ 40MHz alas I putted an oscillator of 72MHz to have a speed of 36MHz. I always wanted to try an 75MHz so I bought one from a fellow Amigan (altcomputing) which arrived yesterday :)

After replacing my former 72MHz oscillator and putting the new 75MHz one... Amiga booted just fine so I tried first some benchmarks via latest version of SysInfo...

The release of excalibur is eminent

The release of Excalibur is eminent

There are only a few features, that I can think of that want, but they going to break some thing maybe, it's time think about uploading a new version, there is 30 changes in this update, so this big update compared to few of the older updates, I lost a lot changes, and head to do most of this twice, nothing makes me more annoyed, well its done.



Welcome to gtmooya's blog! Here you will find information and news about the AmigaOS 4 program 'Assist'. From time to time I may also post news about other Amiga-related projects and musings here.


p-uae v0.1

I decided to do a quick alpha release of my p-uae port, grab it from the aros-archives / aminet, as soon as is accepted there.

This alpha release of P-UAE for AROS is based on the sources at from the 31st January 2013.

This is a *real* alpha version, don't expect anything: It *will* crash, it *will* miss features and so on.

As PUAE is based on the merged WinUAE version, it means, that P-UAE v0.1 is based on WinUAE 2.6.0.

White Rabbits

I started writing this blog while travelling back to New Zealand. It's been a busy and productive couple of weeks but it will be good to get back home to the summer down under. Actually the weather in Northern Europe was quite good until the Arctic blast which hit just as I was leaving the UK. I arrived back in New Zealand to sunshine, a water shortage and hosepipe ban. :-(

Visiting the Magic Kingdom

Happy Easter

Brussels, March 31, 2013

Easter seems like an appropriate time to provide a short update on the development status of a few key components of the upcoming AmigaOS 4.2.

.. and in 24 Bit

SDL can force a 32bit mode, so on a 24bit screen we do a:

SDL_SetVideoMode (current_width, current_height, 32, uiSDLVidModFlags);

And with this magic, PUAE also works in my 24-bit AROS/linux hosted environment :)!

A600: Fun AmigaSYS testing and some recent OS additions

Hey peepz,

After my latest video (thanks for the nice comments btw), I decided to try more stuff to my system.
First of all and just for FUN purposes I decided to convert AmigaSYS 4 AGA to ECS :P
I really think that AmigaSYS is a nice compilation which has it's follower although, I'm not of them.
Sorry folks, ClassicWB all teh way! So... WHO said that AmigaSYS can't run on ECS machines? :D
