Yo, Last night i was using my 32m ems cart with LSDJ, and the LCD screen turned off out of nowhere - but the power LED stayed on.
I tried it with other regular game cartridges, and they still turned off, but relatively longer than it took for the 32M cart.
Here's a video: http://www.youtube.com/watch?v=Ug1Od-dOLeM
The first part is of the 32M flash cart, the LCD screen turning off moments after. The second part is with a pokemon red cart, unintentionally staying on the Nintendo screen, and the third part is of the screen shutting off with the pokemon cart (This, LoZ, and Tetris both took longer than the flash cart to turn off.
I read another post similar to this, and was thinking that the issue could be regarding the ribbon cable?
Thanks, fam.
