N64 versus PS1

Posted by EricBall, 19 January 2018 · 144 views

This past Christmas I bought an N64 for my son (and me) to enjoy my collection of games.  (Although the problem turned out to be dirty cartridges rather than a dead N64.)  He's been having a blast playing Super Mario 64 and the Mario Party games.
This nostalgia rekindled my interest in what is under the hood of both it and the original Pl...

iOS game nearing completion!

Posted by EricBall, 16 December 2017 · 124 views
(See previous entries for more info on the game.)
It's surprising what a little motivation and enthusiasm can accomplish.
One big help was I reached out to YouTuber Torogadude and asked if I could use his compositions as background music and he agreed.  Bonus!  I've also added sound effects and knocked a lot of other items off my...

Back working on my iOS game

Posted by EricBall, 01 December 2017 · 167 views
Back working on my iOS game I'm back to working on my iOS game "Slide Tilt Roll"   in preparation to using it for a presentation to some computer students at my son's high school. 
I updated the MacBook to High Sierra, updated to XCode 9, installed XCode 8 to upgrade the code base from Swift 2.2 to Swift 3.0, then used XCode 9 to bring it up to Swift 4.0. ...

DIY microconsole part 2

Posted by EricBall, 07 September 2017 · 239 views

I now have MAME (2003 - 0.78) up and running, woot!  I've loaded up "the best of" from pre-1986, now I need to figure out how to set the controls beyond the defaults.  This also means I can play the originals rather than the console ports.
I'm also working on getting Colecovision running.  I've created a script which creates a playli...

Sega Forever suffers from poor emulation

Posted by EricBall, 27 June 2017 · 366 views

For some reason I've never gotten into Sega's consoles.  Sure I've played Sonic, but that's about it.  However, when I heard about Sega Forever, I thought I might give it a try - watch a few ads, play a few games.  But now I probably won't bother....

wav2tia redux

Posted by EricBall, 01 June 2017 · 295 views

So, can the TIA generate speech just using normal AUDC waveforms (versus AUDF based PCM)?
The initial results say no.  Although you can hear some of the inflection.
In the attachment is are two WAV files (one with just a simulated TIA output and one with a the input and output in stereo) along the code & executable I used.

TIA Audio Noise Generator redux

Posted by EricBall, 19 May 2017 · 283 views

In the comments for http://atariage.com/...3844-blast-off/ there was some discussion on whether the TIA could be used to generate speech.
Previously I'd done some programming which tried to brute-force fit the TIA waveforms to music.  The results were less than impressive, but speech might be simple enough to achieve better...

Tempest 2017 - value of an unfinished project

Posted by EricBall, 27 March 2017 · 451 views
As my wife often reminds me, I have a habit of not finishing projects once I've started them.  (Usually while pointing at one of them.)  I have to say that I've gotten better at managing this habit (although not necessarily at finishing projects).  I try not to start projects, or at least start spending money instead of just time, unless I...

3D TV is dead

Posted by EricBall, 20 January 2017 · 604 views

I don't dispute that 3D TV never took off, what I find interesting is the TV manufacturers decided to drop a feature - no matter how unused.  
What's interesting is 3D is still popular enough to make 3D films.  (Although my preference is for 2D editions I saw...
