Ver 4 PAL GAP + Magic 3.1 works ok then dies after 5 min
I've installed the mod on top of the chip between the two sets of BIOS points as shown in the attached pic. I do believe my install is a lot neater though :) I have also soldered numerous wires to 5V and Ground.
I found games are booting fine as long as it's on specific Verbatim media. Unfortionately games on the NEW Verbatim(blue bottom) or NEW Sony(silvery green bottom) media are not booting at all :/
The major problem for me, is that after a few minutes the screen kinda goes all jerky(horizontal tearing), switches to Black and White, then dies.
This looks like a heat issue(because of the timing I guess), but I have kept the top of the Magic III chip open and it physically touches the metal plate that screws down on top of it. I have placed strips of insulation tape over the solder points to stop any short circuits occuring.
I need informed comments regarding the placement of mod, whether or not I should adjust the CD laser and if I should try alternate points.
Although this is my first M3.1 install, I have succesfully installed a few NEO4's and numerous PS1 chips. I simply lack experience in the finer details of the M3.1 ;)
