January 07, 2011: Progress
I based this off of a good
On a related note, it turns out that the CPU of the TG16 is a modified version of the MOS Technology 6502. Variations were found in many different early pc's and video game consoles, including the Apple][e, Commodore 64, Atari 2600, and Nintendo Entertainment System. I have been hesitant to put too much work into learning to program for such an uncommon, obsolete platform, but if it would translate to other related platforms, I'd be more interested. I know it wouldn't translate directly, as each CPU "strain" has its own unique optimizations, and I don't know how much different they would be, either. Something to look into, anyway.
I also got a chance to crack open the Game Gear today. First a quick video to show what's wrong with it:
some shots of it before, and the special security bit and screw:
And some words about what to do next:
I also got the other two TG16 consoles apart (the broken ones), and I didn't see anything immediately wrong with them. The fuses look good in both, so I guess I'll need to start checking voltages at various points to see if I can nail down where they're dying.
That's about it for today.
