Hi, folks. I'm writing in just to share a slightly interesting hack I did because I was bored.
Well, I wanted to overclock my Super Gameboy 2 (and other GB systems) but needed to find a crystal faster than the regular 4.19 Mhz in the Gameboy (and, as it turns out, a ~20 Mhz crystal is in the SGB2), so I found a 6.144 Mhz one in the NGPC. I thus swapped the crystals between the NGPC and SGB2. The result: Gameboy games run super slow (along with lower audio pitch) on the SGB2, and the NGPC runs very fast, over 3 times faster than usual, I guess. The games that I tested still run perfectly, though the game speed and audio pitch are all increased. A pretty useless mod, but also smashingly easy to perform.
Next up is hopefully finding some kind of RGB out for the NGPC. Of course, it uses digital RGB and runs at a sync rate that doesn't match up with NTSC frequencies, but do you imagine the TV De Advance (http://www.disgruntleddesigner.com/chrisc/tvde.html) could be somehow used in this regard, as it also digitally captures the GBA screen's signals and generates NTSC video out of it...
Maybe I'll do some more hacking at a later date.
