Back working on my iOS game

Posted by EricBall, 01 December 2017 · 97 views
iOS, STR
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 · 195 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

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 · 247 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.
 
Th...


TIA Audio Noise Generator redux

Posted by EricBall, 19 May 2017 · 237 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 · 386 views
Tempest
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 · 515 views

https://entertainmen...8/3d-tv-is-dead
 
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...


Nintendo Switch musings

Posted by EricBall, 18 January 2017 · 243 views

Poor Nintendo, their idea for a home video game console which can also be used as a portable video game console became a portable console with removable controllers which can be plugged into the TV.
 
From my perspective, Nintendo has two overwhelming challenges when creating a new console:
1. Not understanding their historical successes.
2. Competit...


this ain't my first rodeo

Posted by EricBall, 09 January 2017 · 326 views

The lack of interest in creating levels for Slide Tilt Roll has put a serious black cloud over my plans to release it.  Seeking some inspiration, I started watching the Extra Credits "Making Your First Game" YouTube series  But after watching the first two I started to think - what was my first game?
 
Yes, I created Skeleton / Skeleton+, b...
