It makes me happy that images like this can blow my mind and give me pause for thought.

Batman Forever

Donncha O Caoimh — Fri, 03 Feb 2012 12:45:41 +0000

Batman Forever is an amazing looking Amstrad CPC demo made last year and won first place in the CPC Demo compo at Forever 2011.

Stunning artwork, great effects but perhaps a little bit of the old school yard “my computer is better than your one” in there too. Not too fond of the Commodore 64 are they?

Also check out pushnpop.net, an Amstrad demoscene website! It even has an article on cross-platform development using Linux and Vim!

Thanks Keith for leaving a comment in my last post about this demo. Well worth watching!

In related news, the 1541-II I ordered last week arrived this morning. I’m waiting on the zoomfloppy USB interface to connect it to my laptop now. Fingers crossed it’ll work and it’s not too late for my 20 year old Commodore 64 5 1/4 discs. I tend to agree that if it wasn’t for piracy ancient games would be lost to history now ..

Amazing C64 and Speccy Pixel Art

Donncha O Caoimh — Thu, 02 Feb 2012 13:15:57 +0000

Computers have always been home to amazing artwork. The C64 has so many graphics modes that artists were spoiled for choice near the end of the machine’s life. Luckily, artists are still working on the machine and releasing stuff even now!

You can find some amazing Commodore 64 artwork on c64pixels.com and it’s even sorted by graphics format like hires, FLI and others.

There’s also a comprehensive and detailed collection at CSDB of course but it does have a gallery. You’ll have to click through to each image to view it.

Here’s a wonderful ZX Spectrum gallery. The Speccy was known for attribute clash but despite this you can create really amazing work if you know what you’re doing. Check out this Binary Zone tribute to Speccy artist David Thorpe. You will recognise the loading screens!

Chrome bug: it forgets browsing sessions!

Donncha O Caoimh — Wed, 01 Feb 2012 10:50:13 +0000

I just reported my first Chrome bug but it looks like it’s been known for quite some time, unfortunately.

When Chrome is configured to open the home page on startup it forgets any recently opened tabs if you don’t open those pages before you close the browser again. I’m fairly certain it used to do the right thing before and remember those pages but I’m not sure when that behaviour changed.

Unfortunately Firefox does the same thing. Go to History->Restore Previous Session and it will restore the home page in the same circumstances. I’m almost certain that browser did the right thing in a previous release.

If one were pedantic, the previous session was the single homepage tab and not the dozen tabs I had open before my browser was closed but it’s not what I expect. I’ll close my browser down when I’m doing something intensive but then click on a link in Tweetdeck, laugh at a rage comic and close the browser again before I realise my mistake.

The other thing Chrome has changed is when you have multiple windows open. It only shows the recently closed tabs for one of those windows. Open the home page again and you’ll see the “recently closed” link again where you can open tabs from other windows. You can also press ctrl-shift-t to restore closed windows.

If you hadn’t closed many pages before you shut your browser down you can also use the History page to open previously closed pages selectively. Unfortunately that won’t help if you had pages open for days that you just meant to read when you had time but never found the time. I find myself shoving pages into Read It Later just so I can get back to them at my leisure.

I’ve tried a few Chrome extensions that promised to save my browsing sessions but none worked in the way I’ve described. Does such an extension exist?

Mastering Machine Code on your Commodore 64

Donncha O Caoimh — Mon, 30 Jan 2012 15:30:31 +0000

Before the internet became popular and the web was still in diapers I had a Commodore 64 at home. “Mastering Machine Code on your Commodore 64″ by Mark Greenshields was the first programming book I owned that wasn’t full of BASIC listings and opened my eyes to the wonders of low level assembly development. It was a daunting task learning machine code on my own but I devoured the book and learned so much by looking at the code in demos and games of the time.

The book was originally published in 1984, and I discovered it in a small bookshop next to Paul Street Shopping Centre in Cork sometime in 1990 or 1991. I still remember the excitement I felt at finding any book on the subject. The city library had books on computers, even one or two on building robots and things you could connect to a computer but nothing that explored the C64 in depth.

Based on what I learned in that book and from hacking demos with the aid of an Action Replay I was able to do quite a bit. Nothing amazing but I’m proud of what I did along with others in my demo group way back 20 years ago. I was 16 at the time. I wonder what I’d be hacking on now if I was that age?

You can find a zip file with all our demos in this post. Commodore 64 emulator required!

While flicking through the book I stumbled upon a favourite section, the one on interrupts which I’ve scanned and posted the first two pages of in this post. Here’s another doc on this subject, with the same example code flashing the border 60 times a second. Happy memories.

What was your first programming book?

Ghosts ‘n Goblins is much easier..

Donncha O Caoimh — Sat, 28 Jan 2012 14:26:47 +0000

Games are a hell of a lot easier when they’re trained! Ghosts ‘n Goblins was one of the first games I dived into to see how it worked back in the day. Earlier I played a remix of it’s soundtrack and fired up the game afterwards. I remembered it was hard but compared to games today it’s a demon!

Luckily it was trained and my son and I had an enjoyable half hour shooting the baddies and jumping from platform to platform. I wish the compatible joysticks from back then had more than one button, left/right and up to diagonal jump is a PITA!

In case you’re wondering, a trained game is where the game has been hacked and various cheats added. Usually a fancy intro with swirling graphics and music is added at the start and the group that has hacked the game give you the option of adding infinite lives, time, invulnerability or whatever suits the games. Practically every C64 game you’ll find online has these features now.

Can’t login to Games for Windows Live?

Donncha O Caoimh — Fri, 27 Jan 2012 23:33:33 +0000

I changed my Xbox Live password recently and found I couldn’t login to GFWL this evening. “No problem”, I thought. Just change the password to my new one.

No, I can’t change the password. I can select the password field. It’s active, I can move the cursor back and forward but I can’t type or delete the * characters.

Luckily it was a simple, if non obvious, fix to get around this. Uncheck the “Save my e-mail address and password” and “Sign me in automatically” checkboxes. Now you can select the password field and change it. Don’t forget to “remember” the password again..

Yes, Games for Windows Live is a POS.

1:51 of utter cuteness

Donncha O Caoimh — Thu, 26 Jan 2012 10:29:55 +0000

If you’ve had enough of SOPA, PIPA, ACTA, bailouts, the Euro defaulting, rising oil prices and the rest of the bad news you’ll enjoy this video.

By chance we have a Shitzu at home and a black and white cat (daughter of this cute little fella). They’re friendly but not like these two!

I expect this video will be pulled from Youtube just as soon as the copyright holder matches the song.. Oh well.
