SkillGrid v1.3 is out!
This short video shows the new weapon: https://www.youtube.com/watch?v=Umw_pzdYJkk
Moreover, in addition to the other various improvements, I have given Amiga CD³² users the possibility to enable the hiscore loading/saving from/to NVRAM (I haven't received any feedback relatively to that, so the feature is completely experimental - see readme.txt on the CD).



v1.3 (21.05.2022)
1. Added the BEAM/ULTRA cell (shoots a big beam that is equivalent to 5 beams).
2. Moved the lateral beams of the triple beam one pixel down (to match the shape of the ultra beam).
3. Reduced by 16.7% the occurrences of the DAMAGE cell.
4. Worked on the music playback:
· optimized the decoding;
· optimized the handling of the state;
· removed the pairing of channels on the same side (which caused the title and game over screens music to play louder than the in-game music - an originally intended effect which I have changed my mind about - and did not really work for channel 3 as that channel cannot sustain 28836.5 Hz).
5. Slightly improved the standard music quality by re-downsampling the data after improving the amplification.
6. Changed the keyboard handling so that it executes from a level 3 interrupt handler instead of a level 2 interrupt handler, in order to work around issues/lockups caused by expansion hardware sending INT2 interrupt requests.
7. Replaced [SPACE] with [LEFT ALT] and [RIGHT ALT] as [FIRE] button.
8. Made the startup procedure more robust (especially against audio playback performed with direct hardware access by other programs concurrently).
9. Made various little optimizations.
10. Added the possibility of enabling the loading/saving of the hiscore from/to the NVRAM in the Amiga CD³² bootable version - EXPERIMENTAL FEATURE: CHECK OUT THE README ON THE CD FIRST!
11. Worked on cells graphics:
· fixed colors of beams on BEAM/DOUBLE and BEAM/TRIPLE cells;
· fixed a pixel on the border of the ASTEROIDS, BEAM/DOUBLE and BEAM/TRIPLE cells.
12. Worked on manual and stragegy guide:
· renamed DOUBLE BEAM and TRIPLE BEAM as BEAMS/DOUBLE and BEAMS/TRIPLE, respectively;
· added the information for the BEAMS/ULTRA cell;
· adapted the information for the other BEAMS/* cells;
· added the BEAMS paragraph;
· updated the ASTEROIDS, BEAM/DOUBLE and BEAM/TRIPLE cells images;
· updated the CONTROLS table;
· fixed the outer antialiasing of the BEAM/TRIPLE, BOOST and BRAKE cells images;
· fixed the kerning of the last character of the italic strings.
13. Set the default tool of the manual and strategy guide icons to "Apdf".
14. Updated the artwork to reflect the new beams graphics.

NIce, would this make easier to build new systems based to this?

I recommend everyone try this demo. The quality of the graphics and sound is brilliant and it's great to see a unique game come out on Amiga first, once again.
Any fans of the Amiga & PC classic Moonstone in the house? Enjoy this fan-made budget recreation of the famous intro! Saucepans, dodgy skirts, stop-motion animation and lots of love this way! All feedback appreciated!

Amiga Hardware News / Fifteen years of Sam440ep
« Last post by Elwood on May 21, 2022, 07:12:49 PM »
Dear customers,

It was the year 2007 when we introduced our first “baby”, the Sam440ep. Fifteen years ago. We designed and produced the Sam440ep, a lovely mini-itx motherboard that many enjoyed running AmigaOS 4, AROS and Linux.

At that time we, a bunch of mad amigans, resolved to do our best to bring this hardware to life for all the Amiga Community because it was in dire need of a new computer platform to run AmigaOS.

Without the Sam440ep, the future of AmigaOS would have been very difficult.

After all these years, just as the latest batch of Sam460LE is being produced, we choose to release the electrical schematics of the Sam440ep to the community.

We hope many of you will be happy to see one of the first image of our first project.

The ACube Systems team

My XE G4 has been out of action for years now, but back when it worked, I did use a Radeon 9250 in the AGP slot with no obvious problems. My machine had not been "fixed", it was in the original state.

And I never heard that it should be a problem to use the AGP slot in that situation - but that doesn't necessarily mean it isn't :-).

IIRC, I used an SiI0680 and an SiI3114, and also the internal ports for CD and a boot HD (the internal ports of course in PIO mode).

Best regards,

Can somebody explain to me the AGP port on the XE?  I have had A1XEG4 since 2009.  I have done a lot of work on it to make it stable.  Maybe I should showcase my XE and explain all I have done to make it stable.  It has a few quirks but for the most part it is very stable.  The biggest pitfalls I found with it were memory and the harddrive.   I also will totally disagree that you can only use 1 memory stick for a total of 512Mb of ram.  I have had for years now 2 sticks running 2GB of RAM.  I actually found the memory issue using the serial port to a terminal on boot.  The next huge instability was the HD that came with the box.  It was an old Maxtore and I replaced it with a Seagate 316002 160GB Eide.  I actually have a SATA SIIG 3112 that I was going to swap to see what happens.  The other early on thing I did was shorten the teflon post on the CPU to make the module sit parallel to the MB.  When I got this machine it wouldn't boot at all but as soon as I removed the cpu and reseated it, it started working.

So back to the AGP port.  I was told early on NOT to use the AGP port and use only a PCI Graphics card.  I am currently using a Radeon 9200M 256MB.  I would also take any advice on how to optimize the Graphics to get the most out of this card.

Since I do not use any of the onboard devices except the NIC am I correct on assuming that DMA is not an issue and AGP should be fair game?  I think this would open me up to more modern and faster Radeon cards.  I saw an old post on another board where they said AGP was fair game if the DMA issue was fixed.   I can't tell you if the "fix" was applied to my board without removing it.

You are correct about uBoot.  It was there for the 0680 and others and PIO was selected as the prefered xfer.  I switched it to DMA.

Earlier, I had found in SysMon that I could add the following to the startup-sequence to do the same thing.

IDETOOL -X sii0680ide.device 0 69 >NIL:
IDETOOL -X sii0680ide.device 2 66 >NIL:

It WB boots super fast now.  It seems very stable too.  I will test more.

So this is what it put in my nvgetvar:
Mine would have worked but I put sii0680ide-xfer=F0C0 instead of sii0680ide_xfer=F0C0 :o

12.System:> nvgetvar
bootcmd=menu; run menuboot_cmd

ethact=3Com 3c920c#0
bootargs=root=/dev/ram rw ramdisk=4096
