Reverse engendering of 680x0 assembly code.
Trying to make sense of it all, IRA the disassembler has been really help full to gives some clues; by providing EQU constants for hardware registers, and some other stuff I don't know what is.
Paula sound, so where does that 14bit audio come from?
So where does that 14bit stereo sound come from? You might have wondered, well after reading the hardware reference manual, it explains that 4 audio channels can be combined in to two.
In this mode, one of channels controls the volume (a value from 0 to 63) 6bits, and wave from is (127 to -127) 8bit, so if you add that up 6+8 = 14bit.

New Year’s Resolutions
New Year's Resolutions?
:dancing banana: (sort of)
After more than four months of chasing my own tail on this problem, I had managed to fix up the JIT compiling to let the Kickstart boot using compiled code. (See disclaimer below...)
*Phew*, there were times when I thought I am not going to write this down ever in the blog. I was this >> << close to give it up on some days. Since the world hasn't ended in 2012, I realized I have to go on, there is no escape.

Season’s Greetings
I'm writing this blog to the sound of the annual Christmas pop song medley playing on the radio and with shops and cafes adorned with images of robins, Santa Claus, reindeer and snow.
2012 on the X1000 - A Look Back
Given that it is almost the end of the year, I thought it would be good to look back over the year 2012 and significant releases for AmigaOne X1000 and it operating system AmigaOS4 during that time.
I do know (and acknowledge) that there has been plenty of activity around MorphOS, AROS and Classic AmigaOS3.x platforms too in 2012 (I run all three of these platforms as well), but these are not the focus of this AmigaOne X1000 blog as it runs AmigaOS4. It would be interesting to compare MorphOS 3.1 and AmigaOS 4.1.6 performance on the same X1000 hardware, but that's another story!
SSDR on X1000
I decided to try out a recently released tool called Screen Switching Done Right (SSDR) on my X1000!
Mini Game Review - Santa Monster Shootout on X1000
Santa is working super hard to make it to christmas.
Bringing the Christmas felling to the Amiga desktop, Excalibur now running on my X1000, I might write some words about it.
Mini Game Review - 7 Boings on X1000
Today I am looking at a game called 7 Boings on my X1000, released this year by Mrdarek and available for download on os4depot.net.
Status report
With the bounty in place, my aim was to update the blog more often -- preferably when I had some sort of update. However, my time has been lacking the last few weeks, and I haven't made as much progress as I wanted. But the bounty has surely made me more motivated -- your donations are much appreciated. In order to get some well needed progress, I've earmarked two "mellandagar" (i.e. the days between christmas and new year) to fully focus on Jamiga. I'm hoping nothing will interfere with these plans.
