I can't seem to zoom out to see more than one fractal. Zooming in worked as it made the black "hole" area bigger.

Also I notice that the "bang" landing sound happens prematurely when a block graphically touches the top of another block. The affected block can still be moved and then dropped completely and it bangs again.

Yes, the Powerpak has 32k of ram set aside for save ram. Whenever it sees any sort of write to the save ram, and when you press and hold reset for three seconds, it will prompt to save the ram to the Compact Flash. With this rom, it prompts so it would seem the Powerpak is seeing the sram contents b...

Now that I played it a little longer, the controls seem touchy. I screwed up quite a lot by accidently droping blocks in the wrong places, so I can't get more than aboutt 20 lines. Also blocks have dropped immediatly sometimes by dissapearing and reapearing at the bottom and not sliding. I am not su...

Works on a Powerpak. Strangely silent. Pressing reset gets NTSC warning sometimes.

Tetramino has the usual Tetris clone behavior when a any block goes off the top even off to the side, game ends. The Licensed Tetris version will not end the game quite so fast .... only when the top area is completly filled with blocks.

nes with Powerpak: white screen with text on bottom. So no worky.

Works on a nes with PowerPak. When a block lands on the very top if the stack so that part of that last block goes off the top of the play area, (I mean off to the side, not in the middle) the very next block begins right on top of the last block, ending the game.

Works perfectly on a real nes with a Powerpak.

On a nes with PowerPak, it starts frozen on s single frame. Pushing reset gets it going, but with a strange rolling effect.

Tested on a real nes with a powerpak. Only real glitch is pushing reset....... just blank screen. Not sure how to get the other screens you posted though... pushing buttons tends to make a more messed up version of the previous screen.

The nes doesn't use more than about 300ma. The regulator should handle 13-14v dc from a car.

There seems to be alot of roms with bad headers. I was getting alot of scrambled screens like that and I used "NESToy" to fix bad headers and I don't get those scrambled screens anymore.
